We propose a two-point information security protection mechanism with issue revocability for cloud storage system. Propose system allows sending an encrypted message to a destination via cloud storage server. The sender only needs to know the identity of the receiver however no different data (such as its public key or its corticated). The receiver has to possess two things to decrypt the cipher text. The primary factor is his/her secret key hold on within the pc. The second factor could be a distinctive personal security device that connects to the pc. It is impossible to decrypt the cipher text without either piece. Additional signicantly, once the safety device is stolen or lost, this device is revoked. It cannot be used to decrypt any cipher text. This could be done by the cloud server that is able to right away execute some algorithms to vary the prevailing cipher text to be un-decryptable by this device. This technique is completely clear to the sender. Moreover, the cloud server cannot decrypt any cipher text at any time. The security and potency analysis show that our system is not solely secure but additionally sensible.
