Abstract
In this paper, we present a two-party attribute-based key agreement protocol, which is secure in random oracle model under the Bilinear Diffe-Hellman assumption. It is inspired by a fuzzy identity-based encryption scheme first proposed by Sahai and Waters. The attribute-based key agreement scheme is a new type of identity-based key agreement scheme, in which we can view identity as a set of descriptive attributes. Our scheme not only preserves the advantages of traditional identity-based key agreement protocol, but also provides some new properties, such as hiding the identity information of the individual, increasing the flexibility of key management.
