Nuvoton Technology Assigned Patent

Nuvoton Technology Corporation, Hsinchu Science Park, Taiwan, has been assigned a patent (11,431,478) developed by Lan, Yung-Chi, Taichung, Taiwan, and Wang, Cheng-Chih, Jhubei, Taiwan, for “encryption and decryption system, encryption device, decryption device and encryption and decryption method.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “An encryption and decryption system includes a first electronic device and a second electronic device. The first electronic device includes a memory device and an encryption device. The memory device can store plaintext data. The encryption device can generate first pseudo data and first pseudo key. The encryption device encrypts first pseudo data by the first pseudo key and encrypt the plaintext data by a key, and outputs the ciphertext data generated by encrypting plaintext data by the key. The second electronic device includes a decryption device for generating second pseudo data and the second pseudo key. The decryption device decrypts the second pseudo data by the second pseudo key, and decrypts the ciphertext data by the key, and outputs the plaintext data, which is generated by decrypting the ciphertext data by the key.”

The patent application was filed on December 4, 2019 (16/703,010).
