摘要
引入了α-型密钥共享矩阵的概念，并由α-型密钥共享矩阵构造了密钥共享系统；给出了广义密钥共享系统的概念，构造了广义密钥共享系统。
A new concept of α-type secret sharing matrix is proposed,based on this cocept,we constract a secret sharing system;based on the theory above,we futher proposed a concept of generalized secret sharing system,and construct a generalized secret sharing system.
