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.
