Abstract

The Convertible Authentication Encryption (CAE) scheme, allows the signer to generate an authentic ciphertext signature, which can be recuperated and validated by a specific recipient only. In case of any kind of dispute the recipient is capable enough to convert the ciphertext signature as a normal signature and that can be validated publicly. The CAE schemes are used for transformation of confidential information over insecure networks, because they provide confidentiality, authenticity and integrity for the transmitted message or information. We propose a new CAE scheme by integrating the concepts of ECC- based self-certified public keys and encryption scheme. The security analysis shows that the proposed CAE scheme fulfill the basic security conditions such as indistinguishability of ciphertext signature, unforgeability and non-repudiation. The performance analysis shows that our proposed CAE scheme has little advantage over Wu and Lin scheme regarding computational complexity and timings.
