This is our first IET Information Security special issue from the Internation Conference on and Cryptology, which was held December 1 to 3, Seoul, South Korea, 2021. The aim of ICISC 2021 provide an international forum for latest results research, development, applications within field information security cryptography. In 2021, we received 63 submissions were able accept 23 papers presentation...

This paper investigates verifier-based password authenticated key exchange (PAKE) protocols in the three party setting. We first show that the protocol recently proposed by Li et al. is vulnerable to off-line dictionary attack and unknown key-share attack. Moreover, we also show that the direct elliptic curve (EC) analog of the DL based protocol proposed by Kwon et al. can’t resist the off-line...

Password-Authenticated Key Exchange (PAKE) protocols allow parties to share secret keys in an authentic manner based on an easily memorizable password. Recently, Nam et al. showed that a provably secure three-party passwordbased authenticated key exchange protocol using Weil pairing by Wen et al. is vulnerable to a man-in-the-middle attack. In doing so, Nam et al. showed the flaws in the proof ...

We introduce a novel concept of dual-system simulation-sound non-interactive zero-knowledge (NIZK) proofs. Dual-system NIZK proof system can be seen as a two-tier proof system. As opposed to the usual notion of zero-knowledge proofs, dual-system defines an intermediate partialsimulation world, where the proof simulator may have access to additional auxiliary information about the potential lang...

In cloud storage, public auditing is a more popular data integrity verification technique since it allows users to delegate tasks fully trusted third-party auditor (TPA). However, difficult find such TPA in practical application. Besides, the centralised model makes have bear burdensome work pressure, which limits practicability of existing schemes. this paper, we firstly proposed blockchain-ba...
