Multi Authority Ciphertext Policy Attribute Based Encryption Schemes with Constant Ciphertext Length:A Survey

In Attribute Based Encryption (ABE) scheme, properties assume an imperative part. Attribute Based Encryption is scheme based on attributes and using that secret key is produce and it allows access structure who control the user. Properties have been abused to produce a public key for encrypting information and have been utilized as an access policy to control users. The access policy arrangement can be arranged as either key-policy on the other hand ciphertext policy. In this paper, we survey all Ciphertext Policy Attribute Based Encryption (CP-ABE) scheme with constant cipherttext length and Multi Authority Attribute Based Encryption (MA-ABE) scheme based on ciphertext policy. Also it shows comparison table of all schemes.
