 Okay, hello everyone. As mentioned, my name is Zhengyu Zheng and I'm from the open oiler community and Open Oiler is also one of the top sponsors for these events and I guess you guys might heard the word open oiler in the past in the last in the next few days a lot and we have a booth one of the biggest booths in the exhibition area and actually, as mentioned, I have been working on different open source projects, but I'm quite new to the CCC confidential commenting technologies. I only served as the outreach commenting member for CCC for only like two months. So I guess I can see that everyone in this room knows confidential commenting better than me. So I'm not going to show off my slight skills in front of you guys. So I'm more like introducing the open oiler community and what we have done in the confidential commenting area and as mentioned in the first starting up topic CCC is currently looking to do more activities in the Asia-Pacific area. So we are from the Asia-Pacific area as a community and we have a lot of activities and events. So that's what we're thinking that we can do it together and booths increase the increase the visibility of the confidential computing things. And so what is open oiler? Actually, we are an open source operating system and other projects incubated and operated by the Open Atom Foundation, which is a very fast-growing community and foundation in the Asia area and our vision is to provide an open source OS for the global digital infrastructure and our as I mentioned, we are not only an operating system. We actually have a lot of innovation projects, which includes CCC confidential computing related stuff. So one of my topic today is to show what we have done here and probably we can get some cooperation on both technology and community stuff. And so actually, we have already have a lot of users and the installations in various areas like we have over about almost two million, I think, community users and we have over four million installations. Considering we have only started the community for about three years, just over three years. So I think these numbers can be very good. And as you can see, we have users from all kinds of scenarios and use cases. And that's why we think that open oiler can be very attractive to communities and technologies who wants to expand their use cases in the Asia area. Sorry. So actually, what are our technology advantages comparing to all the other open source OSes? What we are thinking about is that we are trying to combine all the use cases scenarios for one OS because, you know, we have this information technology OS, which is basically the OS we can talk about is maybe CentOS or Ubuntu or other stuff like that. And we also have OS that is built for the communication technologies, which are more real-time thing or others. And we have also the operational technologies, which mostly likely for the embedded or IoT stuff is more real-time thing. And actually, we are thinking about because one thing for the current status is you both have, like for example, you both have a database for the IT technology, which could be MariaDB or MySQL or something else. And you have another DB technology for the communication technology. They could be similar, but there always be some big difference. So we have very a lot of the soft chimneys for the similar applications. So our idea is to, if we can build one OS for what's related to scenarios applications, we can make use of those applications and do not build replicas for each other. So another for the source part is that we are trying to do one OS for various devices, like for server, cloud, edge and embedded. I know that there are also some OSs that can do that. But actually in our community, we are trying to provide a tool that you can easily call the Euler maker and you can easily pick which components you want and build up your own operating system for your own devices and scenarios. Like you want a very small OS, you don't have to wait for the OS vendor to provide it for you. You can build up it easily for your, with our tool for your own use cases. And that's what we are trying to do here. And we have another more like device, remote device operating system is called Open Harmony. It's also incubated with the Open Atom Foundation. So we have a soft bus which can connect very fast, like it's more like a job, air job thing. You can connect to the device very fast with Open Water. So it's more like your Linux device can connect to an Android device very fast, more like that. But both of them are started from scratch. So as I mentioned, we have a lot of innovation projects. We actually have over 400 innovation projects. It's more like, to be honest, it's not like a project. It's over 400 repos. But sometimes one project can have different components. But I can say that it's still over 100 innovation projects. And as an OS, we consider security as one of the very fundamental things. So we have several projects in the security part. One is the thing I want to mention today is the Sec Gear is a computational computing framework. And we have other things like SecPaver and the AMA. Actually, we are trying to provide a full stack or out-of-box use for our customers or users. So we are doing, our community is doing things from the hardware layer to the application layer. So we have a full stack of those things. And you can see that we have already supported diverse computing power empowerment. We can support ARM66 and we can support X86. And we also have very good support for RISC-5 things. And if you want to push your technology scene, I say China. There are a lot of, you know, China-based architectures you may want to adopt. So we have already supported those in our OS. So what you only have to consider about your application layer or libraries. So that's the whole picture, part of the whole picture of the Open Oiler innovation projects. And actually I'm only, actually you can see from my past work experience, I previously worked on the cloud computing and virtualization thing. And actually I'm not an expert on most of those projects. But we, as I mentioned, we have a booth downstairs and we have come about 20 experts this time. So if you guys have want to know anything about Open Oiler and other innovation projects and you can, you are welcome to our booth and discuss with our experts there. And I think after, because when I pray, oh sorry, there are still some Chinese there. When I prepare this material, these slides, I was thinking that I can do some deeper, deeper talk about this. But when I see they're taking, listening to all the previous presentations, I think, oh, those are hardcore people. So I am not going to talk about too many about this because I think everyone in this room knows what those are. We have just implemented most of the things should be implemented for the confidential computing in our second year framework. And we have actually I can, what I can share is that we have to bring two use cases today that we already use second year as their confidential computing technology in their deployment. So I think that's what I can share today. So this one I'm not going to go to depth about this. So you can see we have a security channel, we have remote attention and we have some dev kits for users to be easily adapt all developers to easily develop confidential computing applications. And that's what we have done. And so this is an example about how our development tool can easily make the developers life more easily. And you can see that as I mentioned our OS is aimed to for different or mixed architectures. So I think that's also one of the mainstream in China or Asia I think mainstream in China is to support multiple architectures because for some reasons we cannot only use x86 architecture. So if you want to promote technologies in China you have to consider multi-architecture things. So one of the challenges is to sometimes you have to code twice or three times for different architecture especially for technologies that are more related to the hardware as confidential computing is really closely related to the hardware. So it could be very common to you know program or compile twice for different architecture. And for our set gear we have provided a simplified API for different architecture and it's already done inside in the set gear. And if you follow the API or SDK or rules you can you know have a similar experience for both Intel and ARM x86 programming experience. So I think this one is switch less is one of the I don't know whether this is a very innovative thing or not but we can provide a 10 times performance increase on the ARM x64 platform. We can optimize the RE and TE interact performance by using shared memory to reduce the context switching in the application. And also we can reduce the data copying for that. We have a use case show about this later. Also we have implemented the secure channel to provide the end-to-end protection for our data. And I think this graph shows very clearly what we have done and I think this is quite also quite common in the confidential computing technologies. So I'm not going to talk too much detail about it and it's quite common. So I will share two use cases in China and with actually they are quite large deployments. And I can see that this one is the first one is actually is a certificate agency from Beijing. Actually it's one of one of the very important department. So they use this technology to provide an agile and distributed distributed service based on set gear. So we can see that the cryptographic model is built based on you know we have this ARM 64 server or chip called Kunpo and it can provide some optimized or speed up with this hardware and they can provide this TE environment. And we have this open boiler confidential computing software stack and all the servers provided the service at the same time. So we have very big performance comparing which can be comparing with the you know when you use the hardware encryption machine we can be compatible with that. So this is a very good solution for you know cost saving thing and the performance thing and especially for the cloud applications. Yeah as mentioned here first you need the professional equipment and remote services and the abilities are fixed but after using this we can provide the similar performance with general equipment and in the local service and we can iteration the applications very agile. So and another use case is that we use our studio it's based on Kunpo and we provide condensed database with all these technologies. We can see that we implemented full function circle query and calculation of data ciphertext through technical means and completely solve the problem of data privacy leakage on the cloud and trust of third party services. Our idea of solution is to use the physical isolation or logical isolation of plain text computing space and use access control to make computing and data invisible to outside world to prevent the data leakage. As you can see we still use this the whole secure stack with the operators and equipped data management and the switch list with zero switch to provide a very good performance of this solution and I'm not able to share detailed data because okay be detailed about these solutions but because you know confidential computing technology is always used for you know authorized departments so I cannot share detailed data but I can see that those two use cases have a lot of very big deployments and it's very important in China and I think they are using our secure which means that they believe our secure is both performance and shows very good in both performance and security. So I think that's all for my slides and as I mentioned I'm not a confidential computing expert and but I'm still learning and I think we can cooperate more you know in share area and after that I think I'll be more a confidential computing professional and we can discuss more about the technologies. Thank you very much indeed I made the worst mistake you can make I pronounced your name right but I pronounced the name open Euler wrong so I'm sorry it is open Euler I have a problem with Euler the mathematician's name so thank you thank you any any questions up we've got one immediately from from Paul. I also apologize I pronounced open Euler wrong this morning also as well so I learned something new I didn't know about this project it looks really interesting I said at the start that we need to open more confidential computing in Asia I exclude PRC from that or China from that because it's a hotbed for confidential computing as it is you've shown deployments in China and what about the rest of Asia do you have a plan to sort of penetrate the rest of Asia with this is there some sort of strategic plan for that and if there is is what can the confidential computing consortium help to drive that penetration for you because it does look like a fairly compact solution right yeah actually we have as as you can see that's I think most of you guys didn't did not heard about open Euler before and we are trying to be more global so that's why we are here and so also in the as I thought so you guys mentioned Singapore right we also started a lot of activities in Singapore and we have we have also connected several banks I think in Singapore and they are promoting we are promoting open Euler as a whole so they can select all the projects they want to use in the in their projects and I think the things like secure is one of the plans or deployments that we they could use in their deployments and actually we are doing this with all the we have actually I did not show it yet we have a lot of partners on and members in the open other community and actually because we are or myself we are from the community we are only doing open source stuff and they are like doing our business offering depend on our open source projects and they are doing those selling and deployments I think this is a great example of one of the I know that for certain countries it's difficult to be doing work with with Huawei or other folks in the PRC doing stuff in the open open source the LF makes that possible and and it really get brilliant collaboration yes so I'm really pleased and I'm going to be going to QCon and Shanghai next week and I'm just going to be there I shall I shall see you but any other questions I've got oh it loads okay let's go with that yeah this is more of a question well rather common an encouragement to so fragmentation of hardware is a fact and it's increasingly we see different you know types of hardware in the landscape both due to technical and other reasons and that's why it's even more important to encourage you to get involved into like the standardization activities around confidential computing because I'm thinking right now like ITFT parades so the the two work groups where a lot is happening I think quite a lot there is kind of centered on x86 just because in some cases it matters in some cases doesn't but it's really really good to bring this perspective that there are other architectures and and there are other ways of doing things so I really encourage you to get involved and improve standards in this way yeah yeah I would try yeah so don't don't just stay in the average committee come to all the committees that's what I say that's great uh Osama you have I was just wondering that you mentioned um secured channel and remote attestation in one of the slides so I was wondering if you have um any technical details on whether you are using here the RATLS protocol or do you know some details about the technical all these two protocols are composed together I can actually I cannot answer those questions right now but I can send you the details you wanted to to you because I want to share some details but actually as I mentioned we are just going global and some of our data and materials are in Chinese so I did I did not put any QR codes here because as I checked our first page is in English with this here and other all the other pages are still in Chinese so I cannot I'm sure Osama can translate any Chinese that we are the answer question right yeah yeah any other questions so yep how you mentioned that you are open to discussion and your security experts and CC related experts are there for discussion so how can one contribute to your projects or are you open to other community of course community specifically academics are you open yes yes contributing without membership yeah yeah we we uh we have uh I sorry I don't have the let me check maybe I have uh actually yeah forget we we actually have members but we are because as I mentioned I've been working on other communities for eight years and we know how open source community should be like and we are running this community as you know real open source community so everyone is okay to contribute and we have already I have to say over 3000 developers have contributed code and over 10 000 contributors have you know these issues or anything so everyone is in able to contribute and we are working on the infrastructure to be able to you know work because our code is our code currently our code is hosted on a Chinese vendor um because we have already put it here and the code is very very large where it's not easy to move it directly to github so we are still doing that and I think uh people are uh can contribute to that yeah I have um one last question from May uh which is you showed some um framework the set gear framework um what languages does that support and what does open oil support for compilers uh the set gear is in c and we have uh we support almost every compiler we can do with gcc and we can do with uh rvm and we also do have projects in Rust excellent so anyone has any Fortran or cobalt or algal 68 no no no we wouldn't well thank you very much indeed um and any final thing but that's great really really appreciate it that's really interesting thank you and uh if anyone wants to have a deeper discussion I will be at the open oiler booth with all the other experts and you are welcome to discuss there are some one a lot of people are better than me there so you can have a deeper discussion on technologies thank you
