摘要
En 中文
In the contemporary digital environment, secure search over encrypted data is necessary to prevent the unauthorized data usage practices. To provide data privacy and security fine grained access control is important. For having data privacy data have to be stored onto the cloud in an encrypted form and have to be decrypted before retrieving the message. Encrypting the information is a tedious process for mobiles and also its recovery is a significantly challenging task since the mobile devices have limited bandwidth and battery life. Searching the encrypted data over mobile cloud is a tedious process. To tackle this issue, Cipher text Policy Attribute Based Encryption (CP-ABE) mechanism is proposed. The proposed system will perform computation in cloud rather than the mobile device. This mechanism could effectively prevent malicious searching and decrypting of files. Also, the proposed system support many number of attributes and flexible multiple keyword search patterns in which query file order will not affect the search result. This indicates CP-ABE scheme to improve the efficiency and security.
