Abstract本发明涉及用于WIA-PA安全的分组密码算法工作模式实现方法,包括以下步骤:设置加密或解密操作类型;设置工作模式及分组输入的长度;加载密钥和初始化向量并设定反馈缓存变量;加载数据输入变量并生成AES-128加/解密的输入x;将待加/解密的输入x进行AES-128加/解密操作,生成输出y;更新反馈缓存变量值;根据操作类型和工作模式生成数据输出变量。本发明既能单独实现分组密法算法的多种工作模式,还能够支持IEEE?802.15.4协议中CCM*模式的加/解密功能和认证功能,能够满足WIA-PA网络的信息安全功能和需求。解决了传统上控制过程复杂、处理器工作负载繁重的弊端。
Other AbstractThe invention relates to a method for realizing the working mode of a block cipher algorithm for WIA-PA security. The method comprises the following steps of: setting an encryption or decryption operation type; setting the working mode and the block input length; loading a secret key, initializing a vector, and setting a feedback cache variable; loading a data input variable, and generating an AES-128 encrypted/decrypted input x; performing AES-128 encryption/decryption operation of the input x to be encrypted/decrypted, and generating an output y; updating a feedback cache variable value; and generating a data output variable according to the operation type and the working mode. According to the invention, multiple working modes of the block cipher algorithm can be independently realized; the encryption/decryption function and the authentication function of a CCM* mode in an IEEE 802.15.4 protocol can also be supported; information security functions and requirements of a WIA-PA network can be satisfied; and thus, the disadvantages that the traditional upper control process is complex and the working load of a processor is heavy can be solved.
