Abstract
Narrow-Band Internet of Things (NB-IoT), as a new LPWAN technology, has been applied in many fields, such as smart meter, smart parking, and so on. However, the security issues have become an important factor restricting rapid development of NB-IoT. A lightweight encryption algorithm based on AES and chaotic sequences (LCHAOSAES) is proposed to solve the data security in NB-IoT applications. Firstly, by reducing the number of AES (Advanced Encryption Standard) rounds and combining the three steps of ‘SubBytes’, ‘ShiftRows’ and ‘MixColumns’, time efficiency of LCHAOSAES is improved. Secondly, in order to make LCHAOSAES more secure, Logistic and Tent chaotic systems are adopted to generate dynamic keys for encryption. Finally, the remaining plaintext is encrypted by the keys, which are generated by Logistic and Tent chaotic systems, so that the length of the plaintext is equal to ciphertext. Theoretical analysis and field experiments performed in NB-IoT scenarios highlight significant performance when compared with, for instance, AES_128, LAES.
