Threshold Sharing Scheme for Multiple Secret Keys
Cui Jie-fei · 2004
The paper proposes a threshold sharing scheme for several users to share multiple secret keys,in which each user needs to preserve only a segment from multiple secret keys.If the number of cooperated users is greater than or equal to the threshold value of this scheme,they can cooperate to obtain any secret key.This scheme is strongly secure,as it attributes the security to hardly solving discrete logurithm and square root undes special condition.
