Contactless seed programming method and system thereof

摘要

The invention discloses a contactless seed programming method, belonging to information security field. In the method, a seed programming device obtains a token ID of a dynamic token, obtains corresponding first seed data according to the token ID, communicates with the dynamic token contactlessly, obtains first seed data from the dynamic token, decrypts the first seed data so as to obtain second seed data, encrypts the second seed data with the first data so as to obtain third seed data and sends the third seed data to the dynamic token; and the dynamic token decrypts the seed and updates seed stored in itself. By the invention, programming operation is simplified and programming efficiency is improved by communicating with the dynamic token contactlessly and security is ensured by transferring the encrypted seed during communication between the programming device and the token.

1. A seed programming method, comprising:
obtaining, by a programming device, a token ID of a dynamic token; obtaining, by the programming device, first seed data according to the token ID, connecting and communicating with the dynamic token contactlessly, and obtaining first data from the dynamic token; decrypting, by the programming device, the first seed data so as to obtain second seed data and encrypting the second seed data according to the first seed data so as to obtain third seed data; sending, by the programming device, the third seed data to the dynamic token contactlessly; and decrypting, by the dynamic token, the third seed data according to the first seed data stored in the dynamic token so as to obtain the second seed data and updating the seed data stored in the dynamic token according to the second seed data.
