Abstract: Authentication is the first defense line of user attributes protection and an important process to ensure basic security objectives such as confidentiality and integrity. Any user has specific attributes and all users attributes (data) must be encrypted before stored in the database at the server, so that, no one can access to those attributes even service provider that are considered sensitive information, the difficulty lies in processing data without knowing its content to solve this problem, homomorphic encryption is proposed for authentication process because of it can deal with the encrypted text without the need for decryption and HE creates a common factor that is generated from the original text and its cipher text for matching common factor to access to the system. In this study, proposed elliptic curve algorithm based on HE to encrypt users attributes.
