Havrylova // Modern Problems Of Computer Science And IT-Education : coll. monograph / [ed.: K. Melnyk, O. Shmatko]. – Vienna : Premier Publishing s.r.o., 2020. – Chap. 2. – P. 79-92.https://repository.kpi.kharkov.ua/handle/KhPI-Press/69845The article discusses the mathematical model of the mini-version of the UMAC hashing algorithm, using various cryptoalgorithms as a pseudo-random substrate when generating key data, presents the results of studies of the considered mini-versions. A new approach is proposed to ensure the cryptographic stability of this hashing algorithm based on Mac-Elis crypto-code constructions on modified elliptic codes. This approach will provide the required level of cryptographic security in post-quantum cryptography.enMac-Elis crypto-codeUMAC hashing algorithmEl-Gamal cryptosystemsBook chapterhttp://orcid.org/0000-0003-1647-6444https://orcid.org/0000-0002-2015-8927
