Improved Authentication Protocol for Privacy Protection in RFID Systems

Abstract

identification and to generates variable data in every session. He argued that the DAP3-RS is safe from spoofing attack, replay attack, traffic analysis and etc. Also, the DAP3-RS resolved problem by fixed metaID of Hash-Lock protocol using AES algorithm. However, unlike his argue, attacker can pass authentication and traffic analysis using by same data and fixed hash value on the wireless. We proposed authentication protocol based on AES algorithm. Also, our protocol is secure and efficient in comparison with the DAP3-RS.※ 이 논문은 2012학년도 경북대학교 학술연구비에 의하여 연구되었음 주저자：경북대학교 전자전기컴퓨터학부 임베디드 시스템 연구실,

Entity Authentication and Secure Registration for Lightweight Devices in Internet of Things

“…Readers and tags only perform the symmetric key encryption and the XOR operation to generate a random value for mutual authentication, and thus the protocol is energy efficient. However, the protocol may easily be exposed to an attacker because all the readers and tags have the encryption and decryption key that are not updated [10]. To solve this problem, another system has been proposed, wherein a dynamic ID changed in each communication session is used and only the symmetric key encryption and the XOR operation are used by considering the limited resources of tags.…”
