This piece of work, carried out at LTIA - Laboratório de Tecnologia da Informação Aplicada da UNESP/Bauru ("UNESP/Bauru Applied Information Technology Laboratory") -- explores some of the new demands in terms of electronic documents, such as authenticity, integrity and legal validity, in the development of the "Digital Signature" utility. This utility aims at providing support for Digital Signatures in compliance with both the specifications of open standards for electronic documents and the techniques, practices and procedures approved by ICP-Brasil (the Brazilian PKI), among others. It analyses the open standard format of electronic documents and its support to digital signatures, the interoperability of digital signatures in these formats and the syntax of the W3C XML-Dsig recommendation. In its conclusion, it highlights an utility with support to the Office Open XML and XPS standards as well as the lack of regulation on digital signatures in the OpenDocument Format specification.
