Abstract: Authenticated encryption schemes allow the signer to produce an encrypted message such that only the designated recipient can recover the message and validate its signature. To avoid a later dispute on the repudiation of the signature, we should equip the recipient with the ability for converting the signature into an ordinary one which can be verified by anyone. The scheme with the above capability is called a convertible authenticated encryption (CAE) scheme. Achieving not only the requirements of integrity, authenticity and non-repudiation but also confidentiality, a CAE scheme is suitable for some practical environments such as the transmission of credit card information or the delivery of confidential documents. In the paper, we first propose a generalized CAE scheme based on discrete logarithms and its variants. Then, for facilitating the device with limited computing power and insufficient storage space like smart cards, we further propose a generalized CAE scheme based on elliptic curve discrete logarithms and its variants.
