Secret sharing encryption mode without trusted center
Fang Zheng · Microcomputer & its Applications · 2010
Based on the difficulty of solving the discrete logarithm problem of elliptic curve, this paper discusses the (t,n)threshold encryption scheme and presents a shared secret encrypted mode without a trusted center. In the model, the system public key generated by the members of the cooperative. t or more members can indirectly solve ciphertext. Since the model has little secret information, it has good security and low computational complexity.
