Electronic paper based dynamic password device and realizing method thereof

Abstract

The invention relates to the field of wireless communication technologies, and particularly to an electronic paper based dynamic password device and a realizing method thereof. The electronic paper based dynamic password device is mainly composed of an electronic paper screen module, a password safety module, a crystal oscillation circuit module, a micro-processing unit module and a battery module; the output end of the micro-processing unit is connected with the electronic paper screen module while the input end of the micro-processing unit is connected with the crystal oscillation circuit module, the battery module and the password safety module; and the input end of the password safety module is also connected with an output end where the crystal oscillation circuit module and the battery module are arranged. As the electronic paper with ultra-low power consumption is regarded as a carrier, the power consumption of the dynamic password device is reduced, and the service life of the password device is improved; as the power consumption is reduced, a battery with a smaller capacity can be utilized, the volume of the dynamic password device can be reduced, and a user can carry the password device conveniently.

Description

technical field [0001] The invention relates to the field of wireless communication technology, in particular to an electronic paper-based dynamic cipher and its realization method. technical background [0002] A dynamic password is a combination of random numbers that changes according to a special algorithm. The mainstream forms of generation include mobile phone text messages, hardware tokens, and mobile phone tokens. The advantage of dynamic passwords is that they are easy to use and have nothing to do with the platform. They can be used smoothly through computers, mobile phones, and IPADs. It is widely used in online banking, online games, and telecommunications. Dynamic passwords are currently a hot topic in enterprise applications. More and more companies use dynamic passwords to protect their VPNs, virtualization, servers, and network equipment. Dynamic password solutions for the enterprise market, such as Anhui Shizhi Network Technology Co., Ltd. The password auth...

Problems solved by technology

However, because the cipher requires circuits to continuously support functions such as display, timing and calculation, it consumes a lot of power, and usually ciphers are required to be used for more than several years.

How to meet the need for a cipher that can continue to work without changing the battery has become a difficult point in the design of the cipher; and in order to meet the needs of the cipher for portability, the volume of the cipher must be as small as possible, which limits the battery capacity. size, so the existing dynamic cipher cannot meet our needs in terms of structure and design
