Cryptography on Programmable Smart Cards
Wikarská, Dagmar ; Ricci, Sara (oponent) ; Hajný, Jan (vedoucí práce)
This thesis explores the topic of cryptography schemes using anonymous credentials and revocation. It uses smart cards as anonymous authentication devices with blacklist revocation. Final output of this work is an implementation of a revocation scheme CDH16 on MultOS platform. Secure authentication devices used in banking, transportation, or building access, en- hances anonymity of the user. Implemented protocols could be used as such tools, pre- venting verifier from knowing irrelevant private information. Added revocation scheme protects from misuse of revoked cards by using blacklisting. Blacklisted cards are blocked and verification fails. This requires update of all verifiers blacklist each epoch.
