签密作为实现保密认证通信的一种新技术,具有高效的特点;然而,由于签密中被签密的消息在签名时同时也被加密.由此带来的公开验证问题是亟待解决的.基于密钥交换协议与HK签名方案,提出了一个带指定接收者的可公开验证签密方案.在该方案中,发送方可经由签密者为指定用户生成给定消息的签密密文,在遗嘱协议等的应用中有着积极意义.

Signcryption is a cryptographic primitive that aims at providing confidentiality and authentication simultaneously.While most previous signcryptions only provide the confidentiality and don't provide the publicly delegated authenticity,it is promptly to be resolved problem.Using key exchange protocol and HK signatures publicly verifiable and directed signcryption scheme is proposed.In the scheme,the sender,via the signer,generates valid signcryption text of a gain message.The proposed scheme is publicly verifiable,namely,third partity can verify signature of message.
