By Francis Pelletier | September 12, 2022 at 2:01 pmUniversity of Central Florida Research Foundation, Inc., Orlando, FL, has been assigned a patent (11,398,894) developed by Awad, Amro, Orlando, FL, for “system, method and computer readable medium for file encryption and memory encryption of secure byte-addressable persistent memory and auditing.“
The abstract of the patent published by the U.S. Patent and Trademark Office states: “A method comprising initializing, by a processor, a field identification (FID) field and a file type field in a memory encryption counter block associated with pages for each file of a plurality of files stored in a persistent memory device (PMD) in response to a command by an operating system (OS). The file type field identifies whether each file associated with FID field is one of an encrypted file and a memory location. The method includes decrypting data of a page stored in the PMD, based on a read command by a requesting core. When decrypting, determining whether the requested page is an encrypted file or memory location. If the requested page is an encrypted file, performing decryption based on a first encryption pad generated based on the file encryption key of the encrypted file and a second encryption pad generated based on a processor key of the secure processor.”
The patent application was filed on June 20, 2019 (16/447,242).
