In this paper, the security technology of ad hoc networks is studied.To improve the previous multi-receiver signcryption schemes, an ID-based multi-message and multi-receiver signcryption scheme for rekeying in ad hoc networks is proposed.In this scheme, a sender can simultaneously signcrypt n messeges for n receivers, and a receiver can unsigncrypt the ciphertext to get his message with his own private key.An analysis of this scheme indicates that it achieves authenticity and confidentiality in the random oracle model while being of lower computation and communication overhead.Finally, for the application of our scheme in ad hoc, a threshold key updating protocol for ad hoc networks is given. 展开更多

In this paper, we conduct research on the pragmatics of politeness principle of bulletin board system based on the differences of gender and habits. The openness of the Internet makes all kinds of information received into the vision of an equal chance and web sites in order to improve the hit rate which causes the traffic of commercial purposes such as tabloidization tend to be more negative news spread. To strengthen the research of network language management strategy, it has very important theoretical significance and practical meaning analyzed. Our proposed methodology will help researchers to understand the approaches to use the pragrnatics of politeness. 展开更多
