  1. The paper discusses the development of web, browser / server mode conception and the content and mechanism of network security based on web, and also describes the basic conception and system of cipher theory, symmetric - based data encryption standard and advanced encryption standard and asymmetric - based rsa. it presents a detailed design of secrecy net of digital government, and advances a des - and - rsa - based security model of information exchange, which makes use of symmetric cryptographic algorithm to encrypt plaintext, and introduces public - key algorithm rsa to encrypt session key to compose digital envelope and to realize digital signature
