物联网中基于混合加密的密码安全认证方法OACSTPCD

In view of the high encryption requirements of relevant IoT platforms in China,but the development of encryption technology is slow,a password security authentication system based on hybrid encryption in IoT is designed in the paper.In order to ensure the security authentication of users entering the network,this study adopts the elliptic curve cryptography for the first time.The hybrid encryption technology of ECC and AES realizes the design and implementation of the password security authentication system.By using the charac-teristics of ECC algorithm elliptic curve,it can use the key more convenient than the general encryption technology and obtain the same security.Further,the extended process of AES algorithm is improved to improve the security of the algorithm,and the column obfusca-tion operation is optimized to improve the running speed of the algorithm.Finally,combining the advantages of the two algorithms,a hy-brid encryption system is constructed which is convenient for key management and can take into account both efficiency and security.Fi-nally,a hybrid encryption system that is convenient for key management and can take into account both efficiency and security is a-chieved.Through the experiment,the system technical accounting data,error rate in the acceptable range,the study lays a foundation for other technical research.
