Patent number: 10348497Abstract: Disclosed herein are systems, methods, and non-transitory computer-readable storage media for encryption and key management. The method includes encrypting each file on a computing device with a unique file encryption key, encrypting each unique file encryption key with a corresponding class encryption key, and encrypting each class encryption key with an additional encryption key. Further disclosed are systems, methods, and non-transitory computer-readable storage media for encrypting a credential key chain. The method includes encrypting each credential on a computing device with a unique credential encryption key, encrypting each unique credential encryption key with a corresponding credential class encryption key, and encrypting each class encryption key with an additional encryption key. Additionally, a method of generating a cryptographic key based on a user-entered password and a device-specific identifier secret utilizing an encryption algorithm is disclosed.Type: GrantFiled: January 30, 2018Date of Patent: July 9, 2019Assignee: Apple Inc.Inventors: Michael Lambertus Hubertus Brouwer, Mitchell David Adler

Patent number: 9813389Abstract: Disclosed herein are systems, methods, and non-transitory computer-readable storage media for wireless data protection utilizing cryptographic key management on a primary device and a backup device. A system encrypts a file with a file key and encrypts the file key twice, resulting in two encrypted file keys. The system encrypts each file key differently and stores a first file key on the primary device and transmits one of the encrypted file keys in addition to the encrypted file to a backup device for storage. On the backup device, the system associates the encrypted file key with a set of backup keys protected by a user password. In one embodiment, the system generates an initialization vector for use in cryptographic operations based on a file key. In another embodiment, the system manages cryptographic keys on a backup device during a user password change.Type: GrantFiled: July 22, 2016Date of Patent: November 7, 2017Assignee: Apple Inc.Inventors: Conrad Sauerwald, Vrajesh Rajesh Bhavsar, Kenneth Buffalo McNeil, Thomas Brogan Duffy, Jr., Michael Lambertus Hubertus Brouwer, Matthew John Byom, Mitchell David Adler, Eric Brandon Tamura
