A Novel Approach for Attribute Based Encryption in Cloud Computing
S. Meera, Chebrolu Mandal, C. Scalability · 2013
In Attribute-Based Encryption (ABE) scheme, attributes play a very important role. Attributes have been exploited to generate a public key for encrypting data and have been used as an access policy to control users’ access. The access policy can be categorized as either key-policy or cipher text-policy. In this paper, we describe a CP-ABE based encryption scheme that provides fine-grained access control. In a CP-ABE scheme, each user is associated with a set of attributes based on which the user’s private key is generated. Contents are encrypted under an access policy such that only those users whose attributes match the access policy are able to decrypt.
