Efficient implementation of hash sequence authentication based on RFID

Security for accessing an area need to be noticed. Access restriction can be applied using authentication such as password. Thereby, the strong password is required, but it is hard to remember. Strong password can be generated by using hash function and stored on smart card can be solution. Smart card can be used as access card. Nevertheless, vulnerabilities of the card need to be noticed. Lamport's scheme as hash sequence authentication can be implemented to create dynamic access card which replicate resistant. Hash sequence authentication used to authenticate the prover. The prover should give hash value as input that has result equal with the verifier has. This scheme will be implemented using Arduino Mega ADK. The result of this research is a login hardware prototype.
