Access Control Technique-ABE for Scalable Content Coding in Sharing Networks
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 11
Abstract
Cloud computing emerged as aspired technology in the last few years. With rapid development in Cloud Computing more and more sensitive data is available for sharing in cloud. On other hand providing security features like access control, encryption and decryption became compulsory to avoid vulnerabilities faced during content sharing. This paper presents a novel access control technique-ABE(Attribute- Based Encryption),which is basically a Cipher text Policy. In Multi- message Cipher text Policy(MCP-ABE), access policy is sent along with cipher text. Now, we propose a technique in which the access policy need not be sent along with ciphertext, we are providing privacy for the encryptor party. Here the encrypting party determines the policy of decryption, while the secret key is associated with a set of attributes in ABE scheme where encryptor specified access policies are hidden. In CP-ABE the cipher text is associated with the access policy. Even the legitimate decrypt or cannot obtain the information about the access policy associated with the encrypted data more than the fact that it can decrypt the data. The scheme is efficient and flexible because MCP-ABE allows a content provider to specify an access policy and encrypt multiple messages with in one cipher text such that only the users whose attributes satisfy the access policy can decrypt the cipher text.
