In this paper, we propose a novel security system model for authorization, which refers to the immune system of human being, consisting of three defense-lines. The first line employs authentication techniques, which is the legal premise for subsequent authorization. In second line, blacklist techniques are adopted. Then, the final line is the adaptive immunity, which features the capability of learning...
Flows recombining and information construction are the most important tasks of enterprise. ITIL is a framework that describes the best practices of IT management in enterprise. By introducing the concept of IT service management, we analyze the limitation and deficiency of customer service flows in a telecommunication operator in this paper. Meanwhile, an IT service management implement strategy which...
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...
It is very important to protect the data security in distributed Web applications. In this paper, a file content tamper-proofing system is proposed, which can effectively resist file content tampering, and prevents illegal information spreading. To meet the requirement of authentication speed, a fast authentication algorithm combines file length verification and HMAC is used in the file content tamper-proofing...
SMS4 algorithm is one of the block ciphers used in WLAN, and it is the first commercial block cipher opened by China. In this paper, the principle of SMS4 is introduced. And a one-time cipher algorithm based on SMS4 is proposed and realized, thus the security of the algorithm is improved. The symmetric keys are also one-time by Combining from symmetric key seeds in this paper. A Two-way Authentication...
