Abstract: An SOC implements a security enclave processor (SEP). The SEP may include a processor and one or more security peripherals. The SEP may be isolated from the rest of the SOC (e.g. one or more central processing units (CPUs) in the SOC, or application processors (APs) in the SOC). Access to the SEP may be strictly controlled by hardware. For example, a mechanism in which the CPUs/APs can only access a mailbox location in the SEP is described. The CPU/AP may write a message to the mailbox, which the SEP may read and respond to. The SEP may include one or more of the following in some embodiments: secure key management using wrapping keys, SEP control of boot and/or power management, and separate trust zones in memory.
Abstract translation: SOC实现安全飞地处理器（SEP）。 SEP可以包括处理器和一个或多个安全外设。 SEP可以与SOC的其余部分隔离（例如SOC中的一个或多个中央处理单元（CPU），或SOC中的应用处理器（AP））。 对SEP的访问可以由硬件严格控制。 例如，描述了CPU / AP仅能访问SEP中的邮箱位置的机制。 CPU / AP可以向邮箱写入消息，SEP可以读取并响应。 在一些实施例中，SEP可以包括以下一个或多个：使用包装密钥的安全密钥管理，引导和/或电源管理的SEP控制以及存储器中的单独的信任区域。

Abstract: Some embodiments provide non-transitory machine-readable medium that stores a program which when executed by at least one processing unit of a device synchronizes a set of keychains stored on the device with a set of other devices. The device and the set of other devices are communicatively coupled to one another through a peer-to-peer (P2P) network. The program receives a modification to a keychain in the set of keychains stored on the device. The program generates an update request for each device in the set of other devices in order to synchronize the set of keychains stored on device with the set of other devices. The program transmits through the P2P network the set of update requests to the set of other devices over a set of separate, secure communication channels.

Abstract: A method of restoring confidential information items of a first device to a second device by using a set of servers. The method generates a public and private key pair and ties the private key to the hash of executable code of the servers at the time of generating the public and private keys. The method receives the encrypted confidential information items in a secure object which is encrypted with a user-specific key and the public key. The method only provides the confidential information to the second device when the second device provides the same user-specific key as the key that encrypts the secure object and the hash of the executable code of the servers at the time of accessing the private key to decrypt the secure object matches the hash of the executable code running on the servers at the time of generating the private key.

Abstract: In an embodiment, a system is provided in which the private key is managed in hardware and is not visible to software. The system may provide hardware support for public key generation, digital signature generation, encryption/decryption, and large random prime number generation without revealing the private key to software. The private key may thus be more secure than software-based versions. In an embodiment, the private key and the hardware that has access to the private key may be integrated onto the same semiconductor substrate as an integrated circuit (e.g. a system on a chip (SOC)). The private key may not be available outside of the integrated circuit, and thus a nefarious third party faces high hurdles in attempting to obtain the private key.

Abstract: A user device can segment a secret (e.g., a data recovery key) into a master segment and a shared segment such that possession of both segments is necessary and sufficient to reconstruct the secret. The user device can provide the master segment to a server system. The user device can further segment the shared segment to generate a set of M shares such that any subset of the shares that includes at least a threshold number t of the shares can be used to reconstruct the shared segment, while fewer than t shares provide no information about the shared segment. The M shares can be distributed to shareholder devices. To reconstruct the secret, a recovery device can obtain the master segment and at least t of the M shares, then reconstruct the secret.

Abstract: Some embodiments provide a method for a first device to synchronize a set of data items with a second device. The method receives a request to synchronize the set of data items stored on the first device with the second device. The method determines a subset of the synchronization data items stored on the first device that belong to at least one synchronization sub-group in which the second device participates. Participation in at least one of the synchronization sub-groups is defined based on membership in at least one verification sub-group. The first and second devices are part of a set of related devices with several different verification sub-groups. The method sends only the subset of the synchronization data items that belong to at least one synchronization sub-group in which the second device participates to the second device using a secure channel.

Abstract: The embodiments set forth techniques for implementing a cloud service that enables cloud data to be shared between different users in a secure manner. One embodiment involves a sharing manager and a sharing client, where the sharing manager is configured to manage various data components stored within a storage system managed by the cloud service. These data components can include user accounts, share objects (for sharing data between users—and, in some cases, public users not known to the sharing manager)—as well as various “wrapping objects” that enable data to be logically separated in an organized manner within the storage system. According to this approach, the sharing client is configured to interface with the sharing manager in order to carry out various encryption/decryption techniques that enable the cloud data to be securely shared between the users.
