Ciphertext-Policy Attribute Authentication Scheme Based on Linear Codes

Abstract

Attribute-based authentication (ABA) schemes are mainly constructed on the basis of Lagrange interpolation polynomial, in which the same attributes number of participants of authentication must be greater than or equal to it, and moreover, this threshold is unalterable during once system generation. In this paper, we construct a flexible and efficient attribute-based authentication scheme, which is based on a secret sharing method called Linear Codes Secret Sharing Scheme. This scheme breaks the threshold limit and enjoys diverse authentication participants’ attribute sets by constructing the access structures on linear codes.
