摘要
基于向量空间访问结构提出了一个无分发者的多重访问结构秘密共享方案,避免了因分发者权利过大而产生的不诚实行为.在本方案中,每个参与者只需维护一个子秘密,且子秘密可以重复使用,就能实现对多个秘密的共享.由于离散对数的难解性和单向函数的不可逆性,该方案是安全的.
A multi - access structure multi - secret sharing scheme without dealer based on vector space access structure is proposed, which avoids the dishonest behavior due to the large power of dealer. In this scheme, each participant hold only one subsecret, and his subsecret can be reused for many times, it can implementation to share multiple secret. The scheme is security because of the intractability of discrete logarithm and the irreversibility one -way function.
