System and method for authentication and encryption of electric vehicle payment information based on biometric fusion

Abstract

The invention discloses an electric car payment information authentication and encryption system and method based on biological characteristic fusion. An iris characteristic template and mobile phone IMEI card information are bound and encrypted through utilization of a fuzzy password box; a fingerprint template is converted and a BioCode is extracted; a plurality of pieces of characteristic information is integrated through binary serial connection; a secure channel from a mobile phone to a background database is established through utilization of a public key signature authentication algorithm; and a signature result is verified through utilization of a hash function, thereby realizing a lightweight encryption system of a charging station. The system and the method are relatively good in encryption performance. According to an identification technology fused with a plurality of biological characteristics, the relatively high accuracy and security are achieved; through combination of various algorithms of RSA, the hash function and fuzzy commitment, the multi-biological characteristic mixed encryption is realized; the system security is improved; the attack resistance is improved; the security of user information is ensured; the irreversible conversion is carried out on the biological characteristic template in the encryption process; and even if an attacker intercept data, the biological characteristics of the user cannot be restored.
