<p>Disclosed is a contactless seed writing method, which belongs to the field of information security. The method comprises the steps of: a writing device obtaining a token identifier of a dynamic token; according to the token identifier, obtaining corresponding first seed data; in a contactless manner, connecting to and communicating with the dynamic token to obtain first data from the dynamic token; decrypting the first seed data into second seed data; according to the first data, encrypting the second seed data into third seed data; sending the third seed data to the dynamic token; and the dynamic token decrypting a seed, and updating a seed stored therein. The present invention is in communication with a dynamic token in a contactless manner to enable a writing process to be simple and easy to operate, thereby improving the writing efficiency. When a writing device is in communication with a token, all seeds are transmitted after being encrypted, thereby ensuring security.</p> |
