一种基于ECC算法的安全认证方法

Security Authentication Method based on ECC Algorithm

为了解决传统基于RSA算法的身份认证方法不能满足无人机网络轻量级认证需求的问题,该文设计并实现了基于椭圆曲线ECC(Elliptic Curve Cryptography)算法的身份认证方法。使用ECC数字证书作为合法节点的身份证明,基于椭圆曲线的ECDSA(Elliptic Curve Digital Signature Algorithm)签名算法对节点身份进行签名验证,同时使用ECDH密钥交换算法生成通信所需要的会话密钥,实现以较短长度密钥和较小运算量完成节点间身份认证。

In order to solve the problem that the traditional authentication method based on RSA algorithm cannot meet the light⁃weight authentication requirements of the UAV network.This paper designed and implemented an identity authentication scheme based on Elliptic Curve Cryptography algorithm.The ECC digital certificate is used as the identity proof of the legal node,the ECD⁃SA(Elliptic Curve Digital Signature Algorithm)signature algorithm based on the elliptic curve is used to verify the identity of the node,and the ECDH key exchange algorithm is used to generate the session key required for communication,so as to realize the end-to-end authentication between nodes with short length key and small amount of computation.
