Abstract :
Attribute based encryption has become an active topic within the last few years, which can be regarded as a special identity based encryption integrated with flexible access structure. In this paper, we extend the concept of key encapsulation mechanisms to the attribute-based setting and proposed a key-policy attribute based key encapsulation scheme. The proposed scheme is proved to be IND-CCA2 secure in the standard model under Decisional Bilinear Diffie-Hellman assumption.
