Convertible multi-authenticated encryption scheme with one-way hash function
To send the message to the recipient securely, authenticated encryption schemes were proposed. In 2008, Wu et al. [T.S. Wu, C.L. Hsu, K.Y. Tsai, H.Y. Lin, T.C. Wu, Convertible multi-authenticated encryption scheme, Information Sciences 178 (1) 256–263.] first proposed a convertible multi-authenticated encryption scheme based on discrete logarithms. However, the author finds that the computation...
متن کاملA Robust Convertible Multi - Authenticated Encryption Scheme with One - Way Hash Function
A convertible multi-authenticated encryption (CMAE) scheme allows a group of signers to cooperatively produce a valid authenticated encryption signature and still preserves the characteristic of convertible authenticated encryption (CAE) schemes. In 2008, Tsai proposed a CMAE scheme based on the intractability of one-way hash functions and discrete logarithms. However, we find that Tsai’s schem...
متن کاملConvertible Authenticated Encryption Scheme Without Using Conventional One-Way Function
An authenticated encryption allows the designated recipient to verify the authenticity while recovering the message. To protect the recipient’s benefit in case of a later dispute, a convertible authenticated encryption scheme allows the recipient to convert the authenticated encryption into an ordinary signature so that it becomes a publicly verifiable. This paper shows a universal forgery atta...
متن کاملConvertible authenticated encryption scheme
The digital signature provides the functions of integration, authentication, and non-repudiation for the signing message. In some applications, however, the signature only needs to be verified by some specified recipients while keeping the message secret from the public. The authenticated encryption schemes can be used to achieve this purpose. To protect the recipient’s benefit in the case of a...
متن کاملNew identity-based key-insulated convertible multi-authenticated encryption scheme
Elaborating on the merits of convertible multi-authenticated encryption (CMAE) schemes and keyinsulated systems, we propose a novel identity-based key-insulated convertible multi-authenticated encryption scheme (IB-KI-CMAE), which can effectively reduce the impact caused by the key exposure. Our scheme allows each user to periodically update his private key while the corresponding public one re...
