Problems solved by technology

[0003] The current OTP tokens usually encode the unique serial number into instructions through the communication interface and write them into the memory during production. Not only does it cause potential safety hazards, but also causes a waste of resources, which is not conducive to environmental protection

Embodiment 1

[0019] In the prior art, when the serial number is input by keys, if it is displayed in plain text on the display screen during input, it is easy to be seen by others, causing the serial number to be leaked out, resulting in unsafe use of the OTP token.

[0020] This embodiment provides a method for writing the serial number of the OTP token, such as figure 1 As shown, the method includes:

[0021] In step S101, the serial number is processed according to an encoding algorithm to obtain encoded data.

[0022] Specifically, an encoding algorithm is used to process the original serial number, and the encoding method may be an algorithm such as "exclusive OR operation". For example, the original serial number is "0101", and the operator "1011" is used to perform XOR operation on the original serial number, and the encoded data is "1110". After the original serial number is encoded, even if other people see the input information displayed on the display screen, they cannot obtai...

Abstract

The invention provides a serial number write-in method of a dynamic password board. The serial number write-in method of the dynamic password board comprises the steps of processing serial numbers according to a coded algorithm so as to obtain coded data; conducting a redundant operation on the coded data, and adding redundancy bits to obtain a numeric string; receiving the numeric string input by the exterior by the dynamic password board according to keys; conducting redundancy eliminating computation on the received numeric string by the dynamic password board so as to obtain the coded data; processing the coded data by the dynamic password board according to a decoding algorithm corresponding to the coded algorithm, and obtaining the serial numbers; storing the serial numbers by the dynamic password board. By the adoption of the serial number write-in method, when the serial numbers of the dynamic password board are written in, a communication interface is not required to be reserved for the dynamic password board, and therefore potential safety hazards are not left for the dynamic password board. In addition, the serial numbers are input in a coding mode, the serial numbers can not be easily given away, the safety of the dynamic password board is ensured, and therefore the safety of a user account is ensured.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method for writing a serial number of an OTP token and the OTO token. Background technique [0002] OTP tokens are terminal devices used to generate OTPs, and are widely used in banking, securities, third-party payment, and large enterprise internal scenarios. In the prior art, each dynamic port token has a unique serial number, which uniquely identifies the dynamic port token. Before the dynamic port token leaves the factory, each dynamic port token is pre-written with its unique sequence number. No. [0003] The current OTP tokens usually encode the unique serial number into instructions through the communication interface and write them into the memory during production. It not only creates potential safety hazards, but also causes waste of resources, which is not conducive to environmental protection. Contents of the invention [0004] The present invention aims to...
