A New Convertible Authenticated Encryption Scheme Based on Bilinear Square Diffie-Hellman Problem
Abstract— Convertible authenticated encryption (CAE) scheme is a cryptographic scheme which has been
found numerous practical applications like on-line credit card transactions, confidential contract signing and
the protection of digital evidence, etc. In this paper, we propose a new CAE scheme based on the bilinear
square Diffie-Hellman problem. The proposed scheme is proved secure against adaptive chosen-plaintext
attacks (CPA2) and adaptive chosen-message attacks (CMA) in the random oracle mode. Compared with
previous schemes, ours not only provides better functionalities, but also has provable security.
