Research of Cipher Chip Core for Sensor Data Encryption

In order to enhance safety and improve the multimedia wireless sensor information's confidentiality and information processing speed, the research of wireless sensor data encryption chip core is proposed. Under the action of key, the chip can encrypt plaintext and decrypt cipher text from the input port properly. The key must be randomly distributed. First, this paper analyzes the encrypted multimedia sensor chip architecture. Second, it introduces the design principle of the chip, and analyzes the key randomness. Finally, work function of the designed chip nuclear is verified by the experiments. The cipher chip core can encrypt and decrypt correctly. The conclusion is that the way to design hardware chip can implement encrypt and decrypt data, improving the processing speed, at the same time, strengthening the information security. Chip nuclear can be easily integrated with sensor nodes, and thus reduce the size of our nodes, reducing power consumption.
