Summary:An APB (Advanced Peripheral Bus) bus-based I2C (Inter-Integrated Circuit) communication device is provided. The device comprises: an APB interface module (1), an I2C bus interface module (2), an encryption module (3), a decryption module (4), and a control module (5), wherein the encryption module (3) receives plaintext data and a key from a master via the APB interface module (1), generates, when enabled, ciphertext data according to the plaintext data and the key, and sends the ciphertext data to a slave via the I2C bus interface module (2); the decryption module (4)receives the ciphertext data from the slave via the I2C bus interface module (2) and receives a key from the master via the APB interface module (1), generates, when enabled, plaintext data according to the ciphertext data and the key, and sends the plaintext data to the master via the APB interface module (1). The device can improve the security of data transmission.
