Abstract


In the study of digital signature , digital watermarking , PKI public key infrastructure based on ActiveX technology , combined with the electronic seal Northwest Oilfield Branch production and operation management system application to the asymmetric RSA public key cryptography algorithm as data encryption and data authentication based on key length to a length of 1024 , so far no one can crack reality , through public and private key generation principle , public and private keys , use and management , to elaborate electronic seal application the only program to achieve seal and seal anti- forgery . Digital signature based encryption algorithm based electronic data signing and signature verification function , the digital watermark is a comprehensive digital signature and image processing technology , in addition to the function of the digital signature , electronic data and paper-based data consistency function , the basic principles of PKI public Key Infrastructure using the theory and techniques of public key infrastructure established to provide security services , such as management key to ensure the authenticity of the digital signature , COM, activeX technology to connect an external application interface technologies is the electronic seal the basis , in order to achieve the electronic seal in the corporate office .
