BelT는 128비트 블록 크기와 256비트 키를 가진 블록 암호화기이며, 백화국에서 개발되어 암호화 및 무결성 제어를위한 백화국가 표준 STB 34.101.31의 일환으로 채택되었습니다. 그것의 사양은 2007 년에 예비 표준으로 발행되었으며 2011 년에 최종 표준이되었습니다. BelT는 Feistel 네트워크와 Lai-Massey 체계의 요소를 결합하는 여덟 라운드 구조를 사용합니다.이 논문은 암호화기의 완전한 설명을 제공하고 설계 원칙을 설명합니다.

BelT is a block cipher with a 128-bit block size and a 256-bit key, developed in Belarus and adopted as part of the Belarusian national standard STB 34.101.31 for encryption and integrity control. Its specification was issued as a preliminary standard in 2007, becoming a final standard in 2011. BelT employs an eight-round structure combining elements of a Feistel network and the Lai-Massey scheme. This paper presents a complete description of the cipher and explains the principles underlying its design. Software performance and possible optimizations of BelT are discussed in comparison with those of candidates in the Advanced Encryption Standard (AES) competition.
