基于T-NTRU公钥密码体制的物联网终端安全接入认证

Secure Access Authentication of Internet of Things Terminal Based on T-NTRU Public Key Cryptosystem

现有的物联网终端接入安全认证策略大多是基于椭圆曲线密码算法实现的,计算过程复杂且难以抵抗量子级的攻击.为此提出了一种基于T-NTRU公钥密码体制的物联网终端安全接入认证方案,利用哈希函数通过动态的时间序列生成动态密钥,排除了由固定哈希函数生成的固定密钥易被破解的隐患.实验结果表明,T-NTRU算法能够有效抵抗量子攻击,计算量仅为传统算法的3%左右,对于当前的电力物联网具有很高的实用价值.

Most of the existing Internet of things terminal access security authentication strategies are based on elliptic curve cryptography algorithm,the calculation process is complex and difficult to resist quantum attacks.Therefore,a secure access authentication scheme for internet of things terminals based on T-NTRU public key cryptosystem is proposed.The dynamic key is generated through dynamic time series by using hash function,which eliminates the hidden danger that the fixed key generated by fixed hash function is easy to be cracked.The experimental results show that T-NTRU algorithm can effectively resist quantum attacks,and the amount of computation is only about 3%of that of traditional algorithms.It has high practical value for the current electric internet of things.
