Zettaset Assigned Patent

Zettaset, Inc., Mountain View, CA, has been assigned a patent (10,043,029) developed by Murray, Eric A., Los Gatos, CA, for a “cloud storage encryption.“

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 further 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.”

The patent application was filed on November 15, 2017 (15/813,943).
