With the higher demands for qualities of random sequences, true random sequences are paid more attention because of their higher security features. Although true random sequences have the character of unprediction, they still have problems on big deviation and correlation. The problem on how to get rid of these factors affecting security and obtain good randomicity is becoming the research focus....
Evaluation for computer network information security is helpful for taking corresponding preventive measures. In order to obtain a comprehensive assessment of network security, analytic hierarchy process (AHP) model is proposed to assess the computer network information security. As the criteria and the relevant factors are decomposed hierarchically corresponding to evaluation and judgment of the...
Authentication technology based on one-time-password (OTP) is being used in more important networks applications because of its higher security. But many current schemes based on OTP still use mathematic methods or from simple random origins to get passwords. These passwords often lack of good randomicity and are not able to ensure the security of the systems. In the paper, a new authentication scheme...
In order to make full use of resources in distributed parallel computing system, and reduce general time cost for performing the algorithm, task scheduling and resource management model and low-layer resource supervision-control model are designed and implemented. The unpredictable system behavior is resolved, which is caused by dynamic change resources. The dynamic join-in of resources is allowed...
