【摘要】 AES-CCM算法是WiMAX采用的数据加密算法。通过深入分析AES-CCM算法原理,对802.16协议中CCM模式应用规则存在的安全隐患提出了改进措施。根据802.16协议中CCM模式的应用规则,在富士通3400 WiMAX开发板ARM+VxWorks平台下实现了802.16 MAC PDU的构建、AES-CCM算法、32位CRC校验、8位CRC校验。并且提出和实现了算法在WiMAX设备中的应用方法,最后采用应用模块对算法进行了测试,结果算法模块的正确性和可应用性。更多还原

【Abstract】 WiMAX takes AES-CCM as its packet data encryption algorithm.Through thoroughly analyzing of the AES-CCM algorithm,and according to the characters of specification of 802.16 protocol,improvement measures of CCM pattern apply regulation in 802.16 is put forward.The construction of MAC PDU of 802.16,the AES-CCM algorithm,32 b CRC checking out,8 bit CRC checking out in FUJITSU 3 400 WiMAX development board and ARM+VxWorks platform are realized.The usage of AES-CCM algorithm in WiMAX equipment is brought forward and implemented.At last the program of algorithm is tested and the result can prove correctness,usability of the algorithm module.更多还原
