The design of communication encryption module based on NB-IoT

According to the narrow-band internet of thing (NB-IoT) communication transmission system and encryption requirements of communication in the field of Internet of Things, a design of communication encryption module based on NB-IoT is introduced. The module is based on Huawei Hisilicon Hi2115, it supports UDP and CoAP communication modes, uses NB-IoT wireless communication method to realize encrypted transmission between terminal aware node and network server and can resist common attacks such as copy and replay attack, man-in-the-middle attack and ciphertext-only attack. Module can be widely used in various field, such as access control systems, guy cabinets, etc.
