摘要：
A method for secured exchange of data between an loT device and an loT background system over a mobile communication network, comprises the steps: a) ([4]) By the device provide data-read (DATA-READ) to the SIM; b) ([5]) By the SIM, provide a BOOT-IMSI to the device; c) ([6]) By the device, send an attach request using the BOOT-IMSI to the loT background system over the mobile communication network; d) ([7]) By the loT background system, provide, particularly receive or generate, a random SEED, and send to the SIM over the mobile communication network a challenge message for a challenge-response authentication procedure, the challenge message comprising the random SEED, RAND, AUTN; e) ([8]) By the SIM:
- create a packet including the data-read (DATA-READ); - create an authentication error message and send the packet to the loT background system over the mobile network in the authentication error message; f) At the loT background system:
- receive the packet and extract the data-read (DATA-READ).
- create a packet including the data-read (DATA-READ); - create an authentication error message and send the packet to the loT background system over the mobile network in the authentication error message; f) At the loT background system:
- receive the packet and extract the data-read (DATA-READ).
