Abstract: The sevice migration is a mechanism that take the policy of ‘being off’ when the system is intruded or failure,and it can promote the viability of the service through the migration of sevice in backups.It is analyzed in the paper that the problem in the modern mechanism of the sevice migration,and the secure mechanism of group communication is introduced aiming at the problem,a model of sevice migration based on the disperse logarithm problem and the suppose of DDH is proposed,lastly the security of the new mechanism is analyzed,and which is able to resolve the problem in the customery mechanisms.

Key words: service migration, connection migration, group communication, key agreement

摘要: 主动漂移机制是在系统受到入侵攻击或故障时采取“走为上”的策略,并让服务在服务器池间作漂移运动,从而提高了服务的生存能力。分析了现有的主动漂移机制存在的安全性问题,并有针对性地引入了安全的组通信机制,从而提出了一种在离散对数难题和DDH假设下安全的主动漂移模型,最后对其进行了安全性分析。
