The revolution in information management, brought about in recent years by advances in computer science, has presented many challenges in the field of security and privacy technology. This book presents the proceedings of RFIDsecAE12 Asia, the 2012 workshop on radio frequency identification (RFID) and the internet of things (IoT) Security held in Taipei, Taiwan, in November 2012. RFIDsecAE12 Asia provides researchers, enterprises and governments with a platform to investigate, discuss and propose new solutions to security and privacy issues relating to RFID/IoT technologies and applications. Some of the topics covered in the nine papers included here are: entity relationship extraction and the design of secure API on IoT; practical relay attack implementation; path-checking protocol; secure EPC global Network Services; and the analysis of mutual authentication on RFID. This book will be of interest to all those involved in the field of information management and security.
