ABSTRACT
An extension of the cryptographic technique of identity-based encryption (IBE), our proposed ABE scheme can serve as the basis of an access-control architecture in which entities require no interaction with a trusted authority in order to gain access to sensitive data. Changing scenario of cryptography has led to a change in paradigm of from certificate based public keys and key rings to user-dependent keys which are based on identities of users or their attributes. This is termed as identity based cryptography or attribute based cryptography. Such encryption schemes are much relevant in current scenario of cloud computing and mobile computing where participation of user in transactions is partial, or user-based access control over an encrypted database is required. This paper presents a survey of identity based and attribute based cryptographic primitives
