Abstract:

To solve the problem of the access keys stored in a smart card increasing linearly with the number of registered clouds without third party participated in authentication,an authentication scheme was proposed for multi-cloud environment based on smart card.In the proposed scheme,the authentication was realized between user and multiple clouds without third party participation when the smart card only stored two access key.Thus the storage cost of smart card was reduced effectively.Because there was no public key cryptography,the authentication messages was generated by using XOR homomorphic function and Hash function,thus the computational cost of the smart card and the cloud servers was reduced effectively.Moreover,the proposed scheme also didn’t need to store any user’s information on the cloud servers,thereby reducing the storage and management costs of the cloud servers.The security analysis and the performance analysis show that the proposed scheme is able to resist multiple attacks,which is secure and efficient.

Key words: multi-cloud environment, identity authentication, smart card, XOR homomorphic function
