摘要
本文提出了一个具有指定接收者验证的签名加密方案 .该方案是数字签名与公钥密码体制的有机集成 .与普通数字签名方案相比 ,除了具有认证性、数据完整性外还具有保密性和接收方的隐私性 .然后又利用门限方案构造了一个 (t,n)门限共享验证签名加密方案 .与现有的门限共享验证签名加密方案相比具有数据传输安全、通信代价更小、执行效率更高。
A signature encryption scheme with specified receiver verification is proposed. The scheme perfectly integrates digital signature scheme with public key cryptography system. Compared with common digital signature scheme, it has authentication, secrecy, data integrity and privacy of the receiver. Then, we use threshold scheme to construct a (t, n) threshold shared verification signature encryption scheme. Compared with proposed threshold shared verification signature encryption scheme, it has more secrecy of data transmission, requires smaller communication cost, performs efficiently and decides exactly which verifier tampers secret shadow etc.
