摘要
针对数据集中器通信的安全需求,分析了数据集中器通信受到的主动攻击和被动攻击行为,建立数据集中器通信安全需求模型,提出了一种基于椭圆曲线密码(ECC)的数据集中器通信报文混合密码算法。提出的混合密码算法能够解决单独的ECC加密算法不能实现数字签名问题和椭圆曲线数字签名算法不能实现通信报文保密的问题。研究结果表明,提出的混合密码算法符合数据集中器通信安全需求。
According to the security requirements of data concentrator communication,the active attacks and passive aggressive behaviors suffered by data concentrator communication is analyzed,then a hybrid cryptography algorithm for data concentrator communication message based on elliptic curve cryptography(ECC) is presented by developing a security requirements model in data concentrator communication.The proposed hybrid algorithm is capable of solving the problem of the incapability of individual ECC encryption algorithm of achieving digital signature,and the incapability of the elliptic curve digital signature algorithm of realizing encrypted communication message.The research results show that the proposed hybrid algorithm meets data concentrator communication security demands.
