|Abstract: ||Abstract: A convertible authenticated encryption (CAE) scheme is a better way to simultaneously provide cryptographic schemes with the properties of confidentiality, authenticity and non-repudiation. The authors propose a RSA based secure CAE scheme which is different from previously proposed ones based on the discrete logarithms or elliptic curve discrete logarithms. The proposed scheme has the nice arbitration mechanism allowing the designated recipient to convert the authenticated ciphertext into an ordinary signature without any extra computation efforts or communication overheads for the public arbitration. Additionally, the security requirement of confidentiality against adaptive chosen ciphertext attacks (IND-CCA2) and that of unforgeability against existential forgery on adaptive chosen-message attacks (EU-CMA2) are proved in the random oracle model.
