Cryptanalysis of publicly verifiable authenticated encryption

Zuhua Shao

Abstract

Ma and Chen proposed a new authenticated encryption scheme with public verifiability. This scheme requires less computational costs and communication overheads than the conventional signature-then-encryption approaches. In this letter, we show that the Ma-Chen scheme does not satisfy three security properties: unforgeability, confidentiality and non-repudiation.
