In order to improve the data security over network and provide more effective data protection product, this paper introduces a network data protection system based on combined symmetric key. The system takes into account four main aspects in data protection, including identity authentication, encryption transmission, access controls and encryption storage. The solution combines four aspects into a...
With the development of computer network, the intelligent degree of communication individuals was significantly increased, the requirement of automatic processing on communication message was also significantly increased, but the content of communication message itself hasnpsilat meaning, communication individuals canpsilat understand the content of communication, so resource canpsilat be used adequately,...
A problem in the use of cryptographic mobile agents in the multilevel data warehouse environment is discussed. First, a systematic approach to cryptographic systems is presented. A cryptographic system is a collection of cryptographic primitives and protocols which help to ensure the confidentiality, integrity, and authenticity of data as well as secure key exchange for these primitives. Cryptography...
