    Abstract: The invention is directed to a data-processing system comprising a processor and first encrypted information in a first persistent memory whose level of information leakage is higher than that of a second persistent memory. In the second persistent memory is stored a first cryptographic key for decrypting the first encrypted information, thereby generating therefrom first unencrypted information that is usable by the processor for executing an operation. The same cryptographic key may also be used for encrypting the first unencrypted information, thereby generating the first encrypted information. It is also directed to a method of processing such a data-processing system with an operating system, comprising a writing step for writing first unencrypted information into the first persistent memory, an encryption step for encrypting the first unencrypted information under use of the first cryptographic key, creating therefrom first encrypted information in the first persistent memory, and an access-limitation step for setting the data-processing system to a state in which writing into the first persistent memory is controlled by the operating system. It also relates to a method of executing an operation on such a data-processing system comprising a decryption step for decrypting the first encrypted information under use of the first cryptographic key, thereby generating therefrom first unencrypted information and an execution step for executing an operation by the processor, using the first unencrypted information.

    Abstract: An authorization device (5) is provided for authorizing operations of a remote server (2) requested from user computers (3) via a data communications network (4). The device (5) has a computer interface (6) for connecting the device (5) to a local user computer (3) for communication with the remote server (2), and a user interface (7) for presenting information to a user. Control logic (11) of the device (5) is adapted to use security data to establish between the device (5) and server (2), via the local user computer (3), a mutually- authenticated connection for encrypted end-to-end communications between the device and server. The control logic (11) collects from the server (2) via this connection information indicative of any operations requested by user computers via other connections to the server (2) and requiring authorization by a user of the device (5). This information is presented to a user via the user interface (7) to prompt for authorization by the user. Server operations are controlled in accordance with rule data (18) defining operations requiring authorization by one or more authorizing users. Control logic (15) of the server control apparatus responds to an operation request from a user computer (3) by determining from the rule data (18) whether authorization by at least one authorizing user is required for that operation. If so, the operation is deferred. When a mutually-authenticated connection is established with an authorizing device (5), the control apparatus can supply information indicative of any deferred operations requested from user computers (3) and requiring authorization by the device user. A deferred operation is only performed on receipt of authorization from every authorizing user from whom authorization is required for that operation, providing secure multi-party authorization in a mobile computing environment.

    Abstract: A system and method comprise operating a solid state memory as a cache, where a chunk of data is added to or removed from the cache based on the frequency of occurrence h(X) of the chunk of data in the system. This may mean the number of times the chunk of data is found in the cache, the hard disk drives (HDD), or any collection of memories and storage of the computer. The solid state memory may be a NAND flash memory, and may be located between main memory (or a higher level cache) and the HDDs. The chunks of data may be pages or blocks. Whether a chunk is populated to or evicted from the cache may also depend on how frequently or how recently d(X) the data was accessed/used. The chunks of data may have associated metadata which gives relevant information about attributes of the chunks, and this may be maintained on a watch list.
