摘要： A computer method, computer system, and article for enabling digital signature auditing. The method includes the steps of: receiving at least one signature request issued by at least one application, forwarding a first data corresponding to the received at least one signature request to at least one signing entity for subsequent signature of the first data, storing an updated system state that is computed using a function of: i) a reference system state and ii) a second data corresponding to the received at least one signature request, where the reference system state and the updated system state attest to the at least one signature request, and repeating the above steps, using the updated system state as a new reference system state, where the steps of the method are executed at a server of a computerized system.

摘要： A security device (6) is provided for facilitating management of secret data items such as cryptographic keys which are used by a remote server (2) to authenticate operations of the server (2). The device (6) has a user interface (13), control logic (16) and a computer interface (11) for connecting the device (6) to a local user computer (5) for communication with the remote server (2) via a data communications network (3). The control logic is adapted to establish via the user computer (5) a mutually-authenticated connection for encrypted end-to-end communications between the device (6) and server (2). In a backup operation, the secret data items are received from the server (2) via this connection. The control logic interacts with the user via the user interface (13) to obtain user authorization to backup secret data items and, in response, stores the secret data items in memory (10). To restore secret data items to the server, the control logic interacts with the user via the user interface (13) to obtain user authorization to restore secret data items and, in response, sends the secret data items to the server (2) via said connection.

摘要： This embodiment teaches a variation of GCD-based sieving, building tables of prime products, but intentionally restricting the size of table entries to fit within a single machine word. This combination allows one to mix advantages of the two most popular sieves, while retaining the simple and straightforward structure of the simpler one. Divisor length restriction can provide significant savings in the number of long divisions, but may be implemented with only two very specific primitives. The two primitives offer better optimization capabilities than a fully generic multiword arithmetic library.

摘要： The partitioning of large arrays in the hardware structure, for multiplication and addition, into smaller structures results in a multiplier design which includes a series of nearly identical processing elements linked together in a chained fashion. As a result of simultaneous operation in two subphases per processing element and the chaining together of processing elements, the overall structure is operable in a pipelined fashion to improve throughput and speed. The chained processing elements are constructed so as to provide a pardonable chain with separate parts for processing factors of the modulus.

摘要： A bytecode construction, a method, and a system for optimizing just in time compilation. The bytecode includes several regions wherein a region is a logical sequence of one or more bytecode blocks and the bytecode is annotated with region hints embedded therein. The region hints have a bytecode structure and are designed for instructing a just-in-time, or JIT, runtime environment for JIT compilation of the regions by JIT compilers implemented at nodes of a network. A method and a system for implementing the bytecode construction are also presented.
