This invention relates to a system in which a control computer supplies rapidly changing information concerning a large plurality of data items to a plurality of programmable control units for updating information contained in the memory of each unit. Each programmable control unit memory may contain information relating to a plurality of different items and information relating to a given item may be stored in a number of different locations within the memory, there being no predetermined relat...

A group of bit set and bit clear instructions are provided for a microprocessor to allow atomic modification of privileged architecture control registers. The bit set and bit clear instructions include an opcode that designates to the microprocessor that the instructions are to execute in privileged (kernel) state only, and that the instructions are to communicate with privileged control registers. Two operands are provided for the instructions, the first designating which of the privileged cont...

A server is equipped with a distributor/updater to accept periodic check in by client computers to determine if the client computers' software needs to be updated. The distributor/updater is designed to provide each client computer, determined to require update, with a task list listing a number of tasks to be asynchronously performed at a later point or later points in time by the client computer to update the client computer's software. The tasks may include asynchronous subsequent requests of...

Network resource management systems are provided. A representative network update manager includes an updater coupled to a persistent database and to an administrative application residing on an application server and a memory operable to store a plurality of delayed updates. The network update manager is preferably operable to receive at least one update from the administrative application and subsequently update the persistent database. Methods and other systems for network resource management...

The present invention is to provide a program update apparatus which carry out an updating process automatically in a device built-in system (in particular, in a system for an apparatus that needs to be always operated), and makes the system free from freezing. A downloaded new operation program is stored in a storage area that is separated from a storage area in which a previous operation program that has been operated is stored. Then, the new operation program 24 is activated so that an execut...

A system including a secure LSI 1 establishes a communication path to/from a server 3 (UD1), and receives a common key-encrypted program generated by encryption with a common key and transmitted from the server 3 (UD6 and UD7). The received common key-encrypted program is decrypted to generate a raw program, and the raw program is re-encrypted with an inherent key to newly generate an inherent key-encrypted program, which is stored in an external memory.

A method includes generating new update name lists and providing malicious code protection update information including the new update name lists to host computer systems. In one embodiment, the new update name lists are generated by registering domain names, and only a subset of the registered domain names are used to create an update name list provided to any one of the host computer systems.

A method includes determining that an entire update name list has been attempted and obtaining a verified IP address from a success history file. The success history file includes verified IP addresses of computer systems from which update information has previously been successfully obtained. The method further includes obtaining update information from a computer system located at the verified IP address.
