To satisfy the senders’needs of sending multi-message in the broadcast communication environment,a cer-tificateless signcryption scheme with multi-receiver and multi-message was proposed.The ciphertext no longer contains receiv-ers’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 high-er computational efficiency,satisfy the needs of sending multi-message in broadcast communication environment.%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。
