Interdep. Mag. – 2018. – №195. – P. 27-31.http://openarchive.nure.ua/handle/document/7875The paper is devoted to the security analysis of the Kupyna (DSTU 7564:2014) hash function applied in Merkle tree signature schemes. The paper lists possible attacks on the hash, and their application for signature schemes. The results show expediency of using the Kypuna hash in Merkel schemes based on the performance, security levels and strength against known cryptanalytic attacks.entree traversal problemmerkle tree schemeskupynacryptanalisysdsamssArticle
