In resource-constrained Internet-of-Things networks, the use of conventional message authentication codes (MACs) to provide and integrity is not possible due large size MAC output. A straightforward yet naive solution this problem employ a truncated which undesirably sacrifices cryptographic strength in exchange for reduced communication overhead. article, we address by proposing novel approach...

We have developed a quantum message authentication protocol that provides and integrity of an original using single qubit unitary operations. Our mainly consists two parts: encryption correspondence check. The part is implemented linear combinations wave plates, the check performed Hong–Ou–Mandel interference. By analyzing coincidence counts interference, we successfully proven proposed experim...

All-or-nothing property is a new encryption mode proposed by Rivest and has the property that one must decrypt the entire ciphertext to determine any plaintext block. In this paper, we propose hash functions with all-or-nothing property. The proposed schemes use the existing hash functions without changing their structures, and they are secure against known attacks. Moreover, the proposed metho...

New trends in consumer electronics have created a strong demand for fast, reliable and user-friendly key agreement protocols. However, many key agreement protocols are secure only against passive attacks. Therefore, message authentication is often unavoidable in order to achieve security against active adversaries. Pasini and Vaudenay were the first to propose a new compelling methodology for m...

This paper points out that, contrary to popular belief, allowing a message authentication adversary multiple verification attempts towards forgery is not equivalent to allowing it a single one, so that the notion of security that most message authentication schemes are proven to meet does not guarantee their security in practice. We then show, however, that the equivalence does hold for strong ...
