CRYPTOGRAPHICALLY SECURE TRANSACTIONS WITH OPTICAL CARDS

摘要

A method is provided for writing a record to an optical card. A session key is generated randomly. The session key is encrypted using a private key of a public/private key pair associated with a particular cryptographic-key management device. The record is encrypted using the session key. A serial number for the particular cryptographic-key management device, the encrypted private key, and the encrypted record are optically written to the optical card.
