20080222427 | DEVICE AND METHOD WITH REDUCED INFORMATION LEAKAGE - 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. | 09-11-2008 |
20080226076 | PROVIDING A USER DEVICE WITH A SET OF ACCESS CODES - A method for providing a user device with a set of access codes comprises, in the user device, storing an encryption key and 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. | 09-18-2008 |
20090248580 | SECURE ONLINE BANKING TRANSACTION APPARATUS AND METHOD - A secure online banking transaction apparatus to communicate with a server over a non-secure connection is provided and includes a selector configured to allow for a selection of a mode of the apparatus, a processing unit coupled to the selector and including a secure communication unit, which is configured to set up a secure connection, along which a secure transaction occurs, with the server via the non-secure connection in accordance with the mode, an input unit coupled to the processing unit and configured to allow for a input of data into the apparatus, which is at least partly related to the secure transaction, and an interface coupled to the processing unit and configured to convey at least a status of the secure transaction and the contents off the inputted data. | 10-01-2009 |
20100017459 | DEVICE AND METHOD FOR UPDATING CODE - The invention is directed to a method for a software provider to enable a software-acquiring entity to arrive from an existent first signed piece of code at a second signed piece of code. Both pieces of code were generated at the software provider by use of a first software archive generator under use of generation instructions. The software provider provides to the software-acquiring entity a difference code that comprises the steps necessary to arrive from the first signed piece of code at the second signed piece of code. The difference code is combinable at the software-acquiring entity with the first signed piece of code by a second software archive generator to generate the second signed piece of code. The second software archive generator is therefor to be fed with those generation instructions that were used by the first software archive generator for the generation of both pieces of code. | 01-21-2010 |
20130232584 | METHOD, SECURE DEVICE, SYSTEM AND COMPUTER PROGRAM PRODUCT FOR SECURELY MANAGING FILES - A method, a secure device and a computer program product for securely managing files. The method includes providing a secure device, where the secure device is protected by design against malicious software or malware and adapted to establish a connection to a server via a host, the host connected to the server through a telecommunication network, upon receiving a request for using a file stored on the secure device, processing the request at the secure device according to an updated use permission associated to the file, where the updated use permission is obtained by instructing at the secure device to establish a connection between the secure device and the server via the host and updating at the device the use permission associated to the file, according to permission data sent from the server through the established connection. | 09-05-2013 |
