    Abstract: Techniques are disclosed relating to the secure communication of devices. In one embodiment, a first device is configured to perform a pairing operation with a second device to establish a secure communication link between the first device and the second device. The pairing operation includes receiving firmware from the second device to be executed by the first device during communication over the secure communication link, and in response to a successful verification of the firmware, establishing a shared encryption key to be used by the first and second devices during the communication. In some embodiments, the pairing operation includes receiving a digital signature created from a hash value of the firmware and a public key of the second device, and verifying the firmware by extracting the hash value from the digital signature and comparing the extracted hash value with a hash value of the received firmware.

    Abstract: Techniques are disclosed relating to securely storing data in a computing device. In one embodiment, a computing device includes a secure circuit configured to maintain key bags for a plurality of users, each associated with a respective one of the plurality of users and including a first set of keys usable to decrypt a second set of encrypted keys for decrypting data associated with the respective user. The secure circuit is configured to receive an indication that an encrypted file of a first of the plurality of users is to be accessed and use a key in a key bag associated with the first user to decrypt an encrypted key of the second set of encrypted keys. The secure circuit is further configured to convey the decrypted key to a memory controller configured to decrypt the encrypted file upon retrieval from a memory.

    Abstract: 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.

    Abstract: In some implementations, encrypted data (e.g., application data, keychain data, stored passwords, etc.) stored on a mobile device can be accessed (e.g., decrypted, made available) based on the context of the mobile device. The context can include the current device state (e.g., locked, unlocked, after first unlock, etc.). The context can include the current device settings (e.g., passcode enabled/disabled). The context can include data that has been received by the mobile device (e.g., fingerprint scan, passcode entered, location information, encryption key received, time information).
