Aiming at the defect of the traditional signcryption mechanism and taking the improvement of the wireless com-munication system security as its target,a new signcryption mechanism of the wireless communication system is proposed. The research statue of signcryption mechanism of wireless communication system is analyzed to find the defect existing in current signcryption mechanism. The signcryption mechanism of wireless communication system was improved. The signcryption mecha-nism of wireless communication system was realized with VC++ programming,and compared with other mechanisms. The results show that the mechanism can improve the security of wireless communication system effectively and the efficiency of wireless communication system under the condition of ensuring the communication security,and obtain better performance than that of other signcryption mechanisms.%针对传统签密机制存在的缺陷,以提高无线通信系统的安全为目标,提出一种新型的无线通信系统签密机制.对当前无线通信系统的签密机制研究现状进行分析,找到当前签密机制存在的局限性,对无线通信系统签密机制进行相应改进,采用VC++编程实现无线通信系统的签密机制,并与其他签密机制进行对比.结果表明,该机制可以提高无线通信系统的安全性,在保证通信安全的条件下,提高了无线通信系统的效率,获得了比其他签密机制更优的性能.
