No matter where is in shopping, tax payment, registering in hospital, and reservation for seat and so on. They all can’t be departed from internet. It also provides extreme convenience and efficiency relatively. Especially in the vogue by B2B or B2C, it not only pushes forward the developments of whole world economics, but also gets closer between international, even person to person. But internet is basically an unsecured and unidentified environment. Anyone can counterfeit, steal or forge the information over internet, and so that it would be easy to make many disputes. As the result, information security and identity certification will be an important issue for giving an impetus to network transactions. There is no doubt but fundamental to provide a confidential and safe transmission channel for network. It is also, on the other hand, an important factor how to identify or authenticate each other in a transaction. Digital signature is such a mechanism coming with the tide of fashion for authentication. The signature is hard to be forged based on irreversible one-way hash function or discrete logarithm. It just only uses the private key to prove the document being signed by signer in order to achieve the purpose of authentication. There are, at present, many kinds of e-documents such like DOC files for WORD, PDF files for Acrobat, HTML and so on. But it must have characteristics of open, flexible, public acknowledged format to be a worldwide approved digital signature format. XML (eXtensible Markup Language) would have those of characteristics, and it is very suitable for combining digital signatures with documents. So, if proxy signature can be implemented by XML, the trusted network transactions or electronic official documents would be easily carried out. Unified format can, moreover, enhance the circulation of document exchange; it is especially suitable for applying to general companies. The president, for example, is away on official business; the general manager must act for the president. Proxy signature must be used in this case. Owing to the signature format acknowledged by XML does not support proxy signature, this thesis will extend the standard format for proxy signature and implementation.

碩士 === 國立交通大學 === 電機資訊學院碩士在職專班 === 94 === The world, nowadays, has been flooded with internet. No matter where is in shopping, tax payment, registering in hospital, and reservation for seat and so on. They all can’t be departed from internet. It also provides extreme convenience and efficiency relatively. Especially in the vogue by B2B or B2C, it not only pushes forward the developments of whole world economics, but also gets closer between international, even person to person. But internet is basically an unsecured and unidentified environment. Anyone can counterfeit, steal or forge the information over internet, and so that it would be easy to make many disputes. As the result, information security and identity certification will be an important issue for giving an impetus to network transactions.
There is no doubt but fundamental to provide a confidential and safe transmission channel for network. It is also, on the other hand, an important factor how to identify or authenticate each other in a transaction. Digital signature is such a mechanism coming with the tide of fashion for authentication. The signature is hard to be forged based on irreversible one-way hash function or discrete logarithm. It just only uses the private key to prove the document being signed by signer in order to achieve the purpose of authentication.
There are, at present, many kinds of e-documents such like DOC files for WORD, PDF files for Acrobat, HTML and so on. But it must have characteristics of open, flexible, public acknowledged format to be a worldwide approved digital signature format. XML (eXtensible Markup Language) would have those of characteristics, and it is very suitable for combining digital signatures with documents.
So, if proxy signature can be implemented by XML, the trusted network transactions or electronic official documents would be easily carried out. Unified format can, moreover, enhance the circulation of document exchange; it is especially suitable for applying to general companies. The president, for example, is away on official business; the general manager must act for the president. Proxy signature must be used in this case. Owing to the signature format acknowledged by XML does not support proxy signature, this thesis will extend the standard format for proxy signature and implementation.
