IMPROVED MATHEMATICAL MODEL OF THE POST-QUANTUM ELETRONIC SIGNATURE MECHANISM
Journal Title: КОМП’ЮТЕРНІ НАУКИ ТА КІБЕРБЕЗПЕКА - Year 2018, Vol 4, Issue 12
Abstract
In the paper new electronic signature mechanisms which will be urgent in the post-quantum period devel-opment necessity is grounded. The main one time key mechanisms are briefly described. Problems related with Lamport OTS mechanism and Winternits OTS mechanism related to private and public keys sizes are revealed. Main evaluation criteria are defined. In the paper improved mechanism called POST which can be used in post-quantum period is proposed. POST mechanism is tends to avoid the disadvantages as previous ones. Also processes of signa-ture generation and validation for POST mechanism are presented.
