자원이 제약된 유비쿼터스 장치의 보안을 위한 초경량 LEA 128비트 블록 암호화 아키텍처
An Ultra-Lightweight LEA 128-Bit Block Cipher Architecture for Securing Resource-Constrained Ubiquitous Device
In this paper, we present an efficient hardware design of the 128-bit Lightweight Encryption Algorithm. LEA is a security algorithm developed by the National Security Technology Institute and established as an international standard for cryptography in the International Organization for Standardization and International Electrotechnical Commission for use in a hardware environment. The proposed architecture is based on internal register reuse and resource sharing to lower the LEA encryption/decryption crypto core’s area. The maximum frequency is 190.88MHz and has throughput of 128Mbps. In addition, 301 Flip-Flops, 1151 Look-Up-Tables, and 485 Slices are utilized to present a low-area 128-bit LEA hardware design.

초경량 LEA 128비트 블록 암호화 아키텍처는 자원이 제약된 유비쿼터스 장치에 보안성을 높일 방법으 로, 국가보안기술연구소에서 개발되고 국제표준화기구와 국제전기기술위원회에서 암호 분야 국제 표준으로 제정된 보안 알고리즘인 128비트 Lightweight Encryption Algorithm 알고리즘을 하드웨어 환경에서 설계하여 내부 레지 스터 재사용, 리소스 공유를 통해 LEA 암호화/복호화 모듈을 저 면적으로 구현하였다. Xilinx ISE 14.7 Virtex-5 를 이용하여 합성한 결과, 최대 주파수는 190.88MHz를 달성했으며 최대 128Mbps의 처리 속도를 가진다. 또한, 301개의 Flip-Flop, 1151개의 Look-Up-Table, 485개의 슬라이스로 구현되어 128비트 LEA 알고리즘을 저면적으 로 구현된 하드웨어 디자인을 제시한다.

Ever since next generation convergence technology became one of the most important industries in the nation, computing professionals have encountered a growing number of challenges. Along with scholars and colleagues in related fields, they have gathered in avariety of forums and meetings over the last few decades to share their knowledge, experiences and the outcome of their research. These exchanges have led to the founding of the International Next-generation Convergence technology (INCA) on December 1, 2015. INCA was registered as an incorporated association under the Ministry of Information and Communications. The main purpose of the organization is to improve our society by achieving the highest capability possible in next generation convergence technology.
