Problems solved by technology

Most of the traditional ciphers are implemented by software, that is, codes are written in high-level language and compiled to run on a general-purpose processor. However, the encryption algorithm implemented by this software is limited by the operating frequency of the processor, and it is difficult to achieve high-speed encryption.

In addition, since lightweight cryptography has not yet formed a standard algorithm, the algorithm needs to be iterated continuously, and the design of a dedicated chip requires re-investment in research and development costs

[0004] At present, standard ciphers (such as AES, SM series) have been widely used, but due to the large length of these cipher keys and complex calculations, it is difficult to deploy standard encryption algorithms in miniaturized terminals (such as RFID tags)
