Based on research about network mobility, this paper analyzes the security requirements of internet of things and wireless network based on 6LoWPAN, and designs the security architecture based on 6LoWPAN network, especially for the frequent mobile handoff access and data multi-hop forwarding. The access authentication scheme and data encryption method are designed and implemented based on 6LoWPAN mobile switching. Through comparing with non-symmetric encryption and symmetric encryption, AES pre-shared key encryption scheme is determined to use for 6LoWPAN, and is compared with typical cryptographic algorithms on internet of things platform and Contiki operate system. In experiment, the lightweight security of IoT mobile communication is realized on CC2530 nodes, including the advanced encryption standard, the payload encryption of network data packet and wireless nodes access authentication. Security architecture for mobile switching scenarios are verified, the feasibility of proposed scheme is confirmed.
