Token ring-based secret share update scheme
一种基于令牌环的密钥元更新方案

This paper analyzed the advantages and disadvantages of existing secret share update schemes in Ad Hoc network, presented a token-ring based secret share update scheme. ,This scheme was established according to Ad Hoc network architecture. It included threshold update phase and update group spread phase. Threshold update phase, initiated by cluster head, can effectively avoid the conflict of more than one node initiating secret share update at the same update period. The second phase finished the secret share update of other Certification Authorities (CA) nodes by the update group, which reduced the probability of network storm. In addition, the scheme also put forward a method to tackle the conflict arising from different period secret shares; finally, simulations confirmed the effectiveness of our design.
