In this paper, we propose Threshold Verifiably Encrypted Signature (TVES), which applies threshold cryptography to both signer and adjudicator parties to decentralize

Universally Composable Key-Insulated and?Privacy-Preserving Signature Scheme with?Publicly Derived Pin the blockchain community. One widely adopted technique for privacy preservation is the use of Stealth Address, which serves as a crucial component of Monero’s Ring Confidential Transaction (RingCT) protocol. Liu et al. (EuroS &P’19) introduced and formalized a new signature variant called the Key

Compact Ring Signatures with Post-Quantum Security in Standard Modelntum ring signatures with post-quantum anonymity and post-quantum blind-unforgeability. Assuming the hardness of the learning with errors problem, they proposed a generic construction that transforms any blind-unforgeable (BU) secure signature into a post-quantum ring signature in the standard model

Secure Multi-party SM2 Signature Based on?SPDZ Protocolo two-party or even multi-party and multi-device scenarios. To meet the needs of multi-party signature scenarios, we propose a multi-party SM2 signature scheme based on SPDZ protocol. The basic signature scheme used in this paper is the SM2 digital signature algorithm in the standard “SM2 Elliptic C

The current solution primarily focuses on hiding the balance. However, it is not resistant to LockDown attac

Geometry-Based Garbled Circuits Relying Solely on?One Evaluation Algorithm Under Standard Assumptionircuits (GC) utilize 4 ciphertexts per gate which have attracted great attention for optimizing the performance of communication. Under standard assumption, the best existing optimizations on GC have reduced the number of ciphertexts per gate to 2, while other more efficient optimizations rely on th
