CONTACTLESS SEED PROGRAMMING METHOD AND SYSTEM THEREOF

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.
