De-Synchronization attack on the Hash-based mutual authentication protocol

RFID (Radio Frequency Identification) is a tracking technology that normally uses tags to transfer data to a wireless receiver that can connect to computers. However main concern about RFID system is they’re security and privacy. Up to now many protocols are presented for authentication of tags and readers, but most are vulnerable. Hash-based mutual authentication protocol was presented in 2102 by Cho et al. In 2102 Safkhani et al presented that this protocol is vulnerable to De-Synchronization, impression tag and impression reader attacks, and presented a protocol which was resistant to these kinds of attacks. This paper presents that presented protocol by Safkhani et al is also vulnerable to De-Synchronization and DDoS attacks. In this paper we presented an improvement on Safkhani et al’s (2102) protocol which is resistant to de-synchronization and DDoS attacks
