A Survey on Lightweight Block Ciphers

Ubiquitous and pervasive computing are new era of computing and it needs lightweight cryptographic algorithms for security. Lightweight cryptography is used for resource constrained devices (which have limited memory, limited power and less processing capability) such as radio frequency identification (RFID) tags, con-tactless smart cards, wireless sensor network, health care devices and internet of things (IoT). The design of lightweight block ci-pher has been active research topic over the years. The com-parative evaluations of these block ciphers (which actually reach low cost goal) on any platform is hard. In this paper compara-tive evaluation of selected symmetric key lightweight block ci
