A proof of sequential work allows a prover to convince a verifier that a certain amount of sequential steps have been computed. In this work we introduce the notion of incremental proofs of sequential...
SAT-attack is known to successfully decrypt a functionally correct key of a locked combinational circuit. It is possible to extend the SAT-attack to sequential circuits through the scan-chain by selec...
Proofs of sequential work (PoSW) are proof systems where a prover, upon receiving a statement χχ and a time parameter TT computes a proof ϕ(χ,T)ϕ(χ,T) which is efficiently and publicly verif...
At ITCS 2013, Mahmoody, Moran and Vadhan [MMV'13] introduce and construct publicly verifiable proofs of sequential work, which is a protocol for proving that one spent sequential computational work re...
A Unified Framework for Trapdoor-Permutation-Based Sequential Aggregate Signatures
Aggregate signatures trapdoor permutations ideal cipher model
2018/1/19
We give a framework for trapdoor-permutation-based sequential aggregate signatures (SAS) that unifies and simplifies prior work and leads to new results. The framework is based on ideal ciphers over l...

Identity-based Signatures Sequential Aggregate Signatures the CDH Assumption
2017/4/12
Identity-based sequential aggregate signature (IBSAS) schemes are usually applied to secure network routing and sensor networks, since they allow multiple signers to sequentially produce a short signa...

Linear Distinguishing Attack Linear Sequential Circuit Approximation Achterbahn Stream Cipher
2016/1/23
Achterbahn stream cipher is proposed as a candidate for ECRYPT eSTREAM project which deals with key of length 80-bit. The linear distinguishing attack,which aims at distinguishing the keystream from p...

Computer log files constitute a precious resource for system administrators for discovering
and comprehending security breaches. A prerequisite of any meaningful log analysis is that
attempts of int...

Sequential message authentication code without random oracles
Message authentication code Sequential aggregate
2014/3/11
Katz et al. provided a generic transform to construct aggregate message authentication codes and imposed a lower bound on the length of one aggregate MAC tag. The lower bound shows that the required t...

In computer forensics, log files are indispensable resources that support auditors in identifying and understanding system threats and security breaches. If such logs are recorded locally, i.e., store...
Sequential aggregate signature (SAS) is a special type of public-key signature that allows a signer to add his signature into a previous aggregate signature in sequential order. In this case, since ma...

2012/3/28
Sequential aggregate signature schemes allow n signers, in order, to sign a message each, at a lower total cost than the cost of n individual signatures. We present a sequential aggregate signature sc...
