MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202647123122 A) filed by Qualcomm Incorporated on October 14, 2026, for Data Encryption For Data Transfers Between Semiconductor Dies Using A Keystream Generator.
Inventors include Boucard, Philippe; Lasserre, Serge Bernard; Nejim, Alia; and Gao, Changjian.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: A semiconductor die includes an input interface configured to receive data to be transferred to at least one other semiconductor die. The semiconductor die further includes a keystream generator configured to generate a keystream based on a key and an initial value. The semiconductor die further includes encryption circuitry coupled to the keystream generator. The encryption circuitry is configured to generate a command to initiate decryption and is further configured to generate encrypted data based on the data and the keystream. The semiconductor die further includes an output interface coupled to the encryption circuitry. The output interface is configured to output the command and the encrypted data to a physical interface with the at least one other semiconductor die.
