A convertible authenticated encryption scheme allows a designated receiver to recover and verify a message simultaneously, during which the recipient can prove the dishonesty of t...
Abstract. The CBC-MAC or cipher block chaining message authentication code, is a well-known method to generate message authentication codes. Unfortunately, it is not forgery-secure...
Based on the factorization problem, a modified (t, n) threshold group-oriented scheme with message recovery is proposed. In the proposed scheme, any combination of more than t mem...
We define a new mode of operation for block encryption which in addition to assuring confidentiality also assures message integrity. In contrast, previously for message integrity...
