Construction of Network Security Architecture Based on Formal Specification in Digital Campus

With comprehensive analysis on security requirements of information transmission in digital campus, new primitives in asymmetric and symmetric cryptographic system are designed to describe essential security attributes. Secure information transmission is constructed with composition of the generated primitives and realized with common security technologies. And then, formal analysis shows that, secrecy, integrity, availability, controllability, non-repudiation and identifiability during information transmission can be insured by this architecture. At last, the network security architecture is verified by experiment based on Hadoop, with comparison data on the attacked rate in cloud environment.
