SHA-256 SAT Collision & Preimage Analysis Using CryptoMiniSat with differential cryptanalysis zkbitcoin.com/cryptanalysis/… #PIVX #BTC #ETH #SHA-256 #cryptography #cryptanalysis

collapsing #SHA256 structure (for now at reduced 18 rounds) but sped it up from 20 minutes to 20 seconds zkbitcoin.com/cryptanalysis/… #BTC #ETH #PIVX #POW #cryptanalysis #Bitcoin #ProofOfWork #Mining #SHA256 #BlockchainSecurity

SHA-256 Differential Path Derivation (derives exact paths (verified thus far reduced round 18) as discovered by Prokop in 2016 guided by formulas of Nikolić & Biryukov im 2008) zkbitcoin.com/static/cryptan… #PIVX #Bitcoin $BTC #Ethereum $ETH #SHA256 #SAT #CaDiCaL

broke reduced round 24 SHA-256 collision unfortunately this time solved time shoot up to 8 hours still good zkbitcoin.com/cryptanalysis/… #PIVX #Bitcoin $BTC #Ethereum $ETH #SHA256 #SAT #CaDiCaL

setup similar attack framework for ETH keccak full rounds (24) and non SAT alg used at reduced collision length (24 bits) similar was done for pre-image (but with SAT), will be pushing vars as high as I can, SHA-256 reached 25 rounds #PIVX #Bitcoin $BTC #Ethereum $ETH #SHA256

just to cool excitement keccak indeed is full round 24 but total of 256 bits .. attack extracted just 24 but it does not matter thats a structural weakness detection #PIVX #Bitcoin $BTC #Ethereum $ETH #SHA256
