The proposed API follows the W3C standard, Signature Syntax and Processing (Second Edition). The main structure of the API is built upon a C parser, LibXML2, and a C cryptography library, OpenSSL. The API is written in C programming language and is designed to be flexible to add functions and easy to use. In addition, the API can be ported to Android. The API also enables OpenCL support of iOS devices. Moreover, this work implements a smart card version using a smart card reader, iSmart, to communicate with a smart card performing XML Signature. Finally, the performance of the API and the comparison of compression of signed XML documents are provided in the thesis.844297 bytesapplication/pdfen-USXML數位簽章XML Signaturethesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/253877/1/ntu-101-R99921049-1.pdf
