• In order to improve the comprehensive defense capability of data security in digital twins (DTs), an information security interaction architecture is proposed in this paper to solve the inadequacy of data protection and transmission mechanism at present. Firstly, based on the advanced encryption standard (AES) encryption, we use the keystore to expand the traditional key, and use the digital pointer to avoid the key transmission in a wireless channel. Secondly, the identity authentication technology is adopted to ensure the data integrity, and an automatic retransmission mechanism is added for the endogenous properties of the wireless channel. Finally, the software defined radio (SDR) platform composed of universal software radio peripheral (USRP) and GNU radio is used to simulate the data interaction between the physical entity and the virtual entity. The numerical results show that the DTs architecture can guarantee the encrypted data transmitted completely and decrypted accurately with high efficiency and reliability, thus providing a basis for intelligent and secure information interaction for DTs in the future.
