Widespread attention is recently paid upon RFID system structure considering its ease of deployment overan extensive range of applications. Due to its several advantages, many technical articles are published toimprove its capabilities over specific system implementations. Recently, a lightweight anti-desynchronizationRFID authentication protocol and a lightweight binding proof protocol to guard patientsafety are proposed. This contribution provides enough evidence to prove the first introduced protocolvulnerability to de-synchronization attack. It also provides the other protocol's suffering from desynchronizationattack as well as tracking the movements of the tags. This paper also addressesappropriate solutions to fix the security flaws concerning the two described protocols for secure RFIDapplications.
