Description
Summary:	The article discusses the security problems with wireless sensor networks (WSNs) and radio frequency identification (RFID) devices whose applications range from supply-chain management to home automation and health care. Since these devices are extremely small and have limited power, the task of applying security requires cryptographic services that can perform on a minuscule sized area. The authors give an overview of current cryptographic algorithms and then apply those ideas on a extremely small level. The article continues by giving design recommendations for new algorithms.
