Vehicular Ad Hoc Network (VANET) is considered as a special application of Mobile Ad Hoc Networks (MANETs) in road traffic, which can autonomously organize networks without infrastructure. VANETs enable vehicles on the road to communicate with each other and with road infrastructure using wireless capabilities. In the last few years, extensive research has(More)
The importance of radio frequency identification (RFID) increases for its powerful capabilities for identifying, locating and automatic access control objects. Electronic Product Code Class 1 Generation 2 (EPC-C1G2) is served as the most popular standard for passive RFID tags. In the last year several schemes were proposed to improve security of EPC-C1G2,(More)
The security and privacy of RFID (Radio Frequency Identification) systems becomes an important subject especially for low cost RFID tags. A lot of authentication protocols were proposed to insure the security and in the same time meet the resource limitations. In this paper, we proposed an ultralight weight authentication approach based on permutation, XOR(More)
A Radio Frequency Identification (RFID) system is a contactless automatic identification system that uses small and low-cost tags. The restricted computation ability and limited memory space of low-cost tags make existing RFID systems vulnerable. EPC Class 1 Generation 2 (EPC-C1G2) is the most popular standard for low cost passive RFID tags. For improving(More)
