Cryptanalysis of Curl-P and Other Attacks on the IOTA Cryptocurrency

Cryptanalysis of Curl-P and Other Attacks on the IOTA Cryptocurrency

We present attacks on the cryptography formerly used in the IOTA blockchain, including under certain conditions the ability to forge signatures. We developed practical attacks on IOTA’s cryptographic hash function Curl-P-27, allowing us to quickly generate short colliding messages. These collisions...
