Abstract

Authentication is the first line of defense against compromising confidentiality and integrity. Though traditional login/password based schemes are easy to implement, they have been subjected to several attacks. As alternative, token and biometric based authentication systems were introduced. However, they have not improved substantially to justify the investment. Thus, a variation to the login/password scheme, viz. graphical scheme was introduced. But it also suffered due to shoulder-surfing and screen dump attacks. In this paper, we introduce a framework of our proposed (IPAS) Implicit Password Authentication System, which is immune to the common attacks suffered by other authentication schemes. IPAS is similar to the Pass Point scheme with some finer differences. In every "what youknow type" authentication scheme we are aware of, the server requests the user to reproduce the fact given to the server at the time of registration. This is also true in graphical passwords such as Pass Point.

Abstract

The key generation center could decrypt any messages addressed to specific users by generating their private keys. This is not suitable for data sharing scenarios where the data owner would like to make their private data only accessible to designated users key. so overcome this problem we propose escrow problem which means a written agreement delivered to a third party and Attribute-based encryption (ABE) is a promising Cryptographic approach fine-grained data access control which is provides a way of defining access policies based on different attributes of the requester, environment, or the data object. The KGC can decrypt every cipher text addressed to specific users by generating their attribute keys. This could be a potential threat to the data confidentiality or privacy in the data sharing systems.
