Design Patterns which Facilitate Message Digest Collision Attacks on Blockchains [PDF]
arXiv, 2018 Message digest algorithms are one of the underlying building blocks of blockchain platforms such as Ethereum. This paper analyses situations in which the message digest collision resistance property can be exploited by attackers. Two mitigations for possible attacks are described: longer message digest sizes make attacks more difficult; and, including ...
