CRYPTOGRAPHIC AUTHENTICATION AND IDENTIFICATION METHOD USING REAL-TIME ENCRYPTION

摘要

A method for securing data and safeguarding its origin, in which the data are transmitted from a customer device to a center in an encrypted manner using digital keys and certificates. The encryption includes the steps of generating several key pairs at a center and transmitting keys, key-encrypted keys, and encrypted data to a customer device. The customer device is afterwards able to transmit data encrypted by a safe key to the center. The data may be a PIN code.
