This is a Press Release edited by StorageNewsletter.com on January 19, 2021 at 2:25 pmZettaset, Inc., Los Altos, CA, has been assigned a patent (10,873,454) developed by Murray, Eric A., Los Gatos, CA, and Yankovsky, Maksim, Mountain View, CA, for a “cloud storage encryption with variable block sizes.“
The abstract of the patent published by the U.S. Patent and Trademark Office states: ”Techniques are disclosed for securing data in a cloud storage. Plaintext files are stored as secured, encrypted files in the cloud. The ciphering scheme employs per-block authenticated encryption and decryption. A unique file-key is used to encrypt each file. The file-key is wrapped by authenticated encryption in a wrapping-key that may be shared between files. A centralized security policy contains policy definitions which determine which files will share the wrapping-key. Wrapping-keys are stored in a KMIP compliant key manager which may be backed by a hardware security module (HSM). File metadata is protected by a keyed-hash message authentication code (HMAC). A policy engine along with administrative tools enforce the security policy which also remains encrypted in the system. Various embodiments support blocks of fixed as well as variable sizes read/written from/to the cloud storage.”
The patent application was filed on July 3, 2018 (16/026,279).
