摘要: 为了满足广播通信环境下发送者的多消息发送需求,本文提出可证安全的无证书多接收者多消息签密机制,密文中不再包含接收者身份列表,实现对接收者身份等隐私信息的保护;同时发送者可在一次签密操作中完成多消息发送任务.相较与现有方案而言,除具有保密性和不可伪造性之外,本文机制具有较强的匿名性和较高的计算效率,满足广播通信环境中多消息的匿名发送需求.

关键词: 无证书签密, 多接收者, 多消息, 匿名性, 保密性, 不可伪造性

Abstract: To satisfy the senders' needs of sending multi-message in the broadcast communication environment,a certificateless signcryption scheme with multi-receiver and multi-message was proposed.The ciphertext no longer contains receivers' identity list to protect receivers' privacy.And,as well,the senders can fulfill sending multi-message in a single operation.Compared with the present scheme,apart from confidentiality and unforgery,this scheme is better in anonymity and has a higher computational efficiency,satisfy the needs of sending multi-message in broadcast communication environment.

Key words: certificateless signcryption, multi-receiver, multi-message, anonymity, confidentiality, unforgeability
