A dynamic secret key sharing scheme
Runhua Shi · Journal of Anhui University · 2010
This paper proposed a dynamic secret key sharing scheme based on Shamir's secret sharing,which allowed a dealer owning a secret key to split this secret key among a group of n agents in such a way that any t agents could reconstruct the secret key,but less than t agents couldn't do the same thing.In addition,under the conditions that the dealer didn't hold the secret key any longer,it could dynamically renew the shares,joined or deleted the participant,and increased the threshold value.It kept the extensibility and robustness of the sharing system,and then enhanced its security.Thus,there were many potential applications.
