IET Blockchain, Volume 6, Issue 1, January/December 2026.ABSTRACT Bidding transactions are widely used in scenarios such as government procurement and corporate tendering. However, while traditional blockchain achieves transparency in transactions, it also poses a risk of sensitive information such as bidder identity, quotation, and time being leaked, thereby undermining the fairness and compliance of ...

Generic Transformation to Strongly Unforgeable Signatures [PDF]
, 2007 Recently, there are several generic transformation techniques proposed for converting unforgeable signature schemes (the message in the forgery has not been signed yet) into strongly unforgeable ones (the message in the forgery could have been signed previously). Most of the techniques are based on trapdoor hash functions and all of them require adding

A Review of Offline Blockchain Transaction Systems
IET Blockchain, Volume 6, Issue 1, January/December 2026.Blockchain systems currently rely on constant network connectivity, which limits their utility in remote areas, during network outages or cyber attacks. This paper presents the first systematic study on offline blockchain implementations, analyzing their security and privacy challenges.

IET Communications, Volume 20, Issue 1, January/December 2026.This paper presents a lightweight mutual authentication protocol for VANETs that integrates SDN, edge computing, and ECC to achieve low‐latency, scalable, and privacy‐preserving vehicle communication. The proposed system reduces authentication delay and computational overhead while supporting batch verification and conditional identity traceability ...

Partially blind proxy re-signature scheme with proven security
Tongxin xuebao, 2018 In order to solve the problem of anonymity and controllability of blind proxy re-signature,the concept of partially blind proxy re-signature was introduced by using the idea of partially blind signature.Furthermore,the security definition of partially ...

doaj
International Journal of Distributed Sensor Networks, 2016 The existing proxy signature schemes with the proxy revocation function are proven to be malleable and do not possess strong unforgeability. Motivated by these concerns, a new proxy signature scheme with fast revocation is proposed, and it can be proved ...

On the Quantum Security of OCB
IACR Transactions on Symmetric Cryptology, 2022 The OCB mode of operation for block ciphers has three variants, OCB1, OCB2 and OCB3. OCB1 and OCB3 can be used as secure authenticated encryption schemes whereas OCB2 has been shown to be classically insecure (Inoue et al., Crypto 2019).

Corruption‐Correctable MACs via Combinatorial Group Testing and Erasure Correcting Codes
IET Information Security, Volume 2026, Issue 1, 2026.We have developed a corruption‐correctable message authentication code (CCMAC) that enables data integrity to be verified and corruptions of data to be corrected up to a certain threshold. As in a previous technique for identifying corrupted points, called corruption detectable MAC (CDMAC), the proposed scheme utilizes a system model composed of two ...

Cryptanalysis of an Authentication Scheme Using an Identity Based Generalized Signcryption
Mathematics, 2019 Secure data transmission is a challenging issue in modern data communication. ID based generalized signcryption is a cost effective security primitive which provides authentication or confidentiality, or jointly confidentiality and authentication.

MPC‐Facilitated Adaptive Security Framework for BFT Protocols
IET Information Security, Volume 2026, Issue 1, 2026.The growing use of blockchain and distributed systems requires Byzantine fault tolerant (BFT) protocols that remain secure under dynamic adversaries. However, existing BFT protocols often rely on static assumptions and lack clear mechanisms to detect and remove malicious or denial‐of‐service (DoS) nodes during execution.
