摘　　要：MANET中大多数应用基于群组协同工作,并且群组间的信息共享也能发挥重要作用,由于MANET的不可靠性,安全问题十分突出,所以提出了一种新的安全群组间通信方案。该方案采用基于代理的方式实现了无线自组网中群组间的安全信息共享,群组内采用LKH密钥管理方案,其它群组成员通过与代理的双向认证、密钥协商保证通信安全。分析结果表明,该方案具有较小开销和复杂性,同时能够保障群组内与群组间的通信安全。Most of the applications in MANET are based on group communication, and information sharing between groups also plays an important part. Security must be paid more attention because of the unreliability of MANET, so a secure scheme is proposed. This scheme which is proxy-based could ensure the security of information sharing between groups in MANET. LKH is adopted to implement key management in each group, and members from the other groups achieve secure communication with the group through mutual authe- ntication and key agreement. The analysis proves that the scheme is not only consumes less storage, computation and communication resource but also secure.
