Abstract

A challenge response type dynamic password IC card with information and energy transmitted through radio frequency comprises a dynamic password IC card body. A safety chip is packaged onto the dynamic password IC card body and connected with a radio frequency signal conversion module, the radio frequency signal conversion module is connected with a radio frequency antenna, the radio frequency antenna is connected with a wireless charging control module, the wireless charging control module is connected with a battery, and the battery is connected with the safety chip. The safety chip is further connected with a touch button and a flexible liquid crystal display. The challenge response type dynamic password IC card with information and energy transmitted through radio frequency has the advantages of being convenient to carry, wide in using range and long in service life, and identity authentication can be performed conveniently and fast.

Description

technical field [0001] The invention relates to a challenge-response dynamic password IC card for radio frequency transmission of information and energy. Background technique [0002] With the development of science and technology, more and more attention has been paid to the security of identity authentication, and the dynamic password technology of corresponding strong identity authentication has been more and more applied in various fields. The characteristic of the dynamic password is that it can only be used once and is time-sensitive, so it has a strong ability to resist attacks. In the past, time-based dynamic passwords were used the most. The advantage of time-based dynamic passwords is that they are simple in structure and easy to use, but they are easy to be phished and attacked by man-in-the-middle. Now it is basically upgraded to a challenge-response dynamic password. Although this dynamic password technology is safe, it also has some defects. For example, the u...
