| 摘 要： | Proactive security provides a method for maintaining the overall security of a system,even when individual components are repeatedly broken into and controlled by an attacker.Proactive security is a non-trivial extension of (t 1,n)-threshold cryptosystems,where shares are periodically renewed (without changing the secret) in such a way that information gained by the adversary in one time period is useless for attacking the secret after the shares are renewed.In this paper,we describe the proactive approach and review some basic technologies.We also report the problems need to be study.

| Abstract: | Proactive security provides a method for maintaining the overall security of a system,even when individual components are repeatedly broken into and controlled by an attacker. Proactive security is a non-trivial extension of (t + 1 ,n)-threshold cryptosystems,where shares are periodically renewed (without changing the secret) in such a way that information gained by the adversary in one time period is useless for attacking the secret after the shares are renewed. In this paper, we describe the proactive approach and review some basic technologies. We also report the problems need to be study. |
