摘要
现代鉴别技术,涉及对秘密(也就是密钥)的知识检测,可用合适的算法防止密码被破解,AES算法是现在公认的最有安全度和最有效率的算法。本文首先分析了对称密码和公钥密码及其相应的鉴别模型;然后给出了高级加密标准(AES)算法在PIC单片机上的优化,并进行了仿真;最后对AES加密方案的性能做了进一步的分析;在对加密时间要求不高,并且加密数据量很小的场合,使用8位单片机的软件进行优化和实现,可以简化电路,降低成本和功耗。
Modern identification technology which involves testing some secrets （that is, keys） could use suitable algorithms to prevent the leakage of the password. AES algorithm is now recognized as the safest and most efficient algorithm. This paper firstly analyzed symmetric password and public key cryptography and their corresponding identification model; then gives the method of the Advanced Encryption Standard （AES） algorithm in the PIC＇s single--chip optimization, and its simulation; Finally, further analysis goes to the performance of AES encryption scheme. Using 8 bit single--chip software can simplify the circuit and reduce the cost and power consumption if the occasion does not ask for much in the time and a small amount of data is needed in encryption.
