英文摘要: In this paper, we propose a new lightweight block cipher called LBlock. Similar to many other lightweight block ciphers, the block size of LBlock is 64-bit and the key size is 80-bit. Our security evaluation shows that LBlock can achieve enough security margin against known attacks, such as differential cryptanalysis, linear cryptanalysis, impossible differential cryptanalysis and related-key attacks etc. Furthermore, LBlock can be implemented efficiently not only in hardware environments but also in software platforms such as 8-bit microcontroller. Our hardware implementation of LBlock requires about 1320 GE on 0.18 μm technology with a throughput of 200 Kbps at 100 KHz. The software implementation of LBlock on 8-bit microcontroller requires about 3955 clock cycles to encrypt a plaintext block. © 2011 Springer-Verlag Berlin Heidelberg.
