Convertible 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 کاملConvertible 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 Novel (t,n) Threshold Convertible Authenticated Encryption Scheme
Authenticated encryption schemes allow the signer to generate an authenticated ciphertext such that only the designated recipient has the ability to recover the message and verify its corresponding signature. It can be seen that authenticated encryption schemes are applicable to lots of E-Commerce applications like credit card transactions, since these schemes simultaneously fulfill the securit...
متن کاملA new convertible authenticated encryption scheme with message linkages
In this article, we present an authenticated encryption scheme with message linkages used to deliver a large message. To protect the receiver’s benefit, the receiver can easily convert the signature into an ordinary one that can be verified by anyone. Several feasible attacks will be discussed, and the security analysis will prove that none of them can successfully break the proposed scheme. 20...
