Abstract: An example method for migrating a live operating system from a first computing device to a second computing device is provided. The example method comprises (a) providing register values of a processor of a first computing device to a second computing device which is in communication with the first computing device; (b) providing contents of a dynamic random access memory, DRAM, of the first computing device to the second computing device; (c) storing the register values in a protected memory of the second computing device, wherein the protected memory is separate from a memory used by the second computing device during normal operation of the second computing device; (d) storing the contents of the DRAM of the first computing device in a DRAM of the second computing device; and (e) loading the register values from the protected memory to registers of a processor of the second computing device.

Abstract: Implementations are directed, for example, to a method that includes receiving, at a data storage system from a client, a key search token that has not been used to encrypt data records or keywords associated with the data records. The key search token is independent of an encryption key used to encrypt the data records associated with the key search token. The method further includes determining an encrypted data record associated with the key search token, and transmitting the determined encrypted data record to the client. Implementations of the client are also provided.
