Abstract: Methods and apparatus are provided for provisioning an operating system image from a server (2) to an untrusted user terminal (4) via a data communications network (3). A trusted device (5) such as a pocket USB device has tamper-resistant storage (9) containing bootloader logic, for controlling booting of a user terminal, and security data. On connection of the trusted device (5) to an untrusted user terminal (4), the user terminal is booted via the bootloader logic on the trusted device. Under control of the bootloader logic, a connection is established to the server (2) via the network (3) and the server is authenticated using the security data on the trusted device (5). An operating system boot image is received from the server (2) via this connection. The boot image is used to provision an operating system image from the server (2) to the user terminal (4) for execution of the operating system at the user terminal (4).

Abstract: PROBLEM TO BE SOLVED: To provide a method for reducing the quantity of data to be transmitted, and simplifying the change of functionality, and holding the security characteristics of a signed code such as a Java code container. SOLUTION: In this method for a software provider, a software acquisition entity 20 is allowed to reach from an already existing first signed code piece 11 to a second signed code piece 12. The both code pieces are generated under the use of a generation instruction by using a first software archive generator 2 at the software provider side. The software provider provides a difference code 4 including a step necessary for allowing the software acquisition entity 20 to reach from the first signed code piece 11 to the second signed code piece 12 to the software acquisition entity 20.

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: The invention is directed to a method for distinguishing reachable objects and non-reachable objects in an object-based application in a system with a volatile memory and a non-volatile memory. The object-based application operates in the non-volatile memory on the objects, whereof at least one is a root object. Each root object is processed by writing for each object that is reachable from the root object, a positive reachability information into the volatile memory and marking those objects in the non-volatile memory as reusable memory, for which no positive reachability information is present in the volatile memory.

Abstract: A method for providing a user device with a set of access codes comprises, in the user device, storing an encryption key a an identification code, and sending a message containing the identification code to a server via a communications network. In the server, an encryption key is stored corresponding to the key stored in the user device, allocating the set of access codes on receipt of the identification code from the user device. A look up function is performed based on the identification code received in the message to retrieve the key from storage. The set of access codes is encrypted using the retrieved key to produce an encrypted set. A message containing the encrypted set is sent to the user device via the network. In the user device, the encrypted set received from the server is decrypted using the key in storage, and storing the decrypted set of access codes for use by a user of the user device.
