Abstract: A request to perform a cryptographic operation is received, the request including a first identifier assigned to a key group, the key group comprising a plurality of second identifiers, with the plurality of second identifiers corresponding to a plurality of cryptographic keys. A second identifier is determined, according to a distribution scheme, from the plurality of second identifiers, and the cryptographic operation is performed using a cryptographic key of the plurality of cryptographic keys that corresponds to the second identifier that was determined.

Abstract: Electronically signed data is persistently stored in data storage. After the passage of time, the data may be accessed and presented to a trusted entity for verification of the data. The trusted entity may have access to secret information used to sign the data. The trusted entity may use the secret information to verify an electronic signature of the data. One or more actions may be taken based at least in part on a response provided by the verification system.

Abstract: A service includes an associated service request throttling system. The throttling system constrains the rate at which service requests are fulfilled by the service, and also provides throttling information to the service. The throttling system controls service throughput by implementing a throttling bucket. The throttling bucket has an associated bucket level which indicates, to the service, an amount of service requests that can be satisfied before throughput limitations are imposed by the throttling system. The bucket level may be modified in response to service requests, service request characteristics, or environmental parameters. In some examples, operational parameters of the throttling system may be configured by users of the service to constrain data exfiltration. The bucket level itself may be used by the service to expand or constrain access privileges granted to particular users.

Abstract: Techniques are disclosed for a device that presents a mass storage device to a computing environment, and which stores data written to the device by the computer in a network storage service. The device also presents files stored in the network storage service to the computer as though those files were stored on a mass storage device.
