| 摘 要： | 给出一种改进的多重秘密共享的门限方案，在该方案中管理者可以安全有效地共享多个密钥，成员可以根据不同的共享密钥计算不同的子密钥。该方案采用知识签名的方法能够有效地抵御管理者欺骗和成员欺骗，具有良好的可扩展性，是安全且高效的。

| Abstract: | Based on key value GALT for the new standard IEEE1516 of HLA, the important significance of GALT in time management for HLA is discussed. The realization of GALT in the general time advancing algorithm and the reason for deadlock are analyzed, four sufficiency conditions for deadlock in the HLA time advancing, such as mutex condition, request holding condition, non-deprive condition and loop waiting condition, are researched and proved. The conception of dynamic slide model is put forward, and a non-deadlock time management algorithm based on dynamic slide model is designed. Finally, the new arithmetic for setting the reasonable value of Lookahead reasonably is analyzed. |
