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.

On the security of joint signature and encryption revisited
Journal of Mathematical Cryptology, 2016 In 2002, An et al. [1] proposed three generic conversions of signcryption, ℰt𝒮${\mathcal{E}t\mathcal{S}}$, 𝒮tℰ${\mathcal{S}t\mathcal{E}}$ and 𝒞tℰ&𝒮${\mathcal{C}t\mathcal{E}\&\mathcal{S}}$ from the primitive encryption scheme and signature scheme ...

Token‐Guided Flow Tracing for Auditable Zero‐Knowledge Smart Contract Transfers
IET Information Security, Volume 2026, Issue 1, 2026.Private transfers on public smart contract blockchains hide transaction values and private transfer links, but accountable privacy requires controlled auditability. Existing auditable zero‐knowledge transfer systems make per‐transaction audit information available to an authorized auditor, but their audit model may allow the auditor to inspect ...

Two‐Party Adaptor Signature: New Definition and Efficient Constructions From ECDSA
IET Information Security, Volume 2026, Issue 1, 2026.Adaptor signature (AS) has gained increasing popularity lately due to its widespread adoption in different Blockchain applications such as atomic swaps and payment channels. Two‐party AS enhances the security of the signing key by splitting it into two parts. Erwig et al.

Cryptanalysis and design of signature schemes with identity ambiguity in the standard model
Tongxin xuebao, 2011 The security and flaw of the two anonymous signature schemes called ZLW（2008） and LHMM（2009） were analyzed,where the ZLW scheme couldn’t provide signed message verifiability and the LHMM scheme couldn’t resist on the multiple-known-signature existential ...
