Convertible Authenticated Encryption Scheme with Hierarchical Access Control
Convertible authenticated encryption (CAE) scheme with hierarchical access control has crucial benefits to the transmission of digital evidence. Such a scheme allows a judicial policeman to generate an authenticated ciphertext and only a designated investigator of Investigation of Bureau, Ministry of Justice (MJIB) has the ability to decrypt the ciphertext and verify the corresponding signature...
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 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...

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...
