In this paper, we propose a blind signature scheme and three practical educed schemes based on elliptic curve discrete logarithm problem. The proposed schemes impart the GOST signature structure and utilize the inherent advantage of elliptic curve cryptosystems in terms of smaller key size and lower computational overhead to its counterpart public key cryptosystems such as RSA and ElGamal. The ...

Most of the lightweight block ciphers are build as S-P networks or Feistel networks, their generalization or variations. We represent the lightweight Feistel ciphers GOST and MIBS, and Generalized Feistel cipher Skipjack by quasigroup string transformations. For obtaining suitable representation we use the fact that Feistel round functions that are bijections can be considered as orthomorphisms...

This study investigates using the GOST encryption algorithm to enhance security within QRCode Indonesia Standard (QRIS). Given ubiquity of QR Codes in digital transactions, particularly for Micro, Small, and Medium Enterprises (MSMEs), robust measures are paramount. We evaluated algorithm’s ability secure data Code, converting code into an encrypted carrier decipherable only via a specially-equ...

Square pyramid and conical test-pieces have been machined. Disadvantages of square pyramid in respect to conical test-piece have been shown. Following the proposal of Bossoni [1], ISO presents a test-piece for simultaneous, 5-axis movement in ISO/DIS 10791-7 [4] without specifying the exact position and orientation of the test-piece. Therefore in this paper, test-pieces milled at four different...
