摘要： There is disclosed a computer entity having a trusted component which compiles an event log for events occurring on a computer platform. The event log contains event data of types which are pre-specified by a user by inputting details through a dialogue display generated by the trusted component. Items which can be monitored include data files, applications drivers and the like. The trusted component operates through a monitoring agent which may be launched onto the computer platform. The monitoring agent may be periodically interrogated to make sure that it is operating correctly and responding to interrogations by the trusted component.

摘要： In a computing platform, a trusted hardware device (24) is added to the motherboard (20). The trusted hardware device (24) is configured to acquire an integrity metric, for example a hash of the BIOS memory (29), of the computing platform. The trusted hardware device (24) is tamper-resistant, difficult to forge and inaccessible to other functions of the platform. The hash can be used to convince users that that the operation of the platform (hardware or software) has not been subverted in some way, and is safe to interact with in local or remote applications.In more detail, the main processing unit (21) of the computing platform is directed to address the trusted hardware device (24), in advance of the BIOS memory, after release from ‘reset’. The trusted hardware device (24) is configured to receive memory read signals from the main processing unit (21) and, in response, return instructions, in the native language of the main processing unit (21), that instruct the main processing unit to establish the hash and return the value to be stored by the trusted hardware device (24). Since the hash is calculated in advance of any other system operations, this is a relatively strong method of verifying the integrity of the system. Once the hash has been returned, the final instruction calls the BIOS program and the system boot procedure continues as normal.Whenever a user wishes to interact with the computing platform, he first requests the integrity metric, which he compares with an authentic integrity metric that was measured by a trusted party. If the metrics are the same, the platform is verified and interactions can continue. Otherwise, interaction halts on the basis that the operation of the platform may have been subverted.

摘要： The preferred embodiment of the invention comprises a computer system which employs a trusted display processor (260), which has a trusted processor (300) and trusted memory (305, 315, 335, 345) physically and functionally distinct from the processor and memory of the computer system. The trusted display processor (260) is immune to unauthorised modification or inspection of internal data. It is physical to prevent forgery, tamper-resistant to prevent counterfeiting, and has crypto functions (340) to securely communicate at a distance. The trusted display processor (260) interacts with a user's smartcard (122) in order to extract and display a trusted image, or seal (1000), generate a digital signature of the bitmap of a document image and control the video memory (315) so that other processes of the computer system cannot subvert the image during the signing process. The user interacts with the trusted display processor via a trusted switch (135).

摘要： In order to facilitate a user's ability to trust a computing environment, a trusted computing device (2) is arranged to challenge other devices in the computing environment and to record a log of the facilities available within the computing environment and an indication of whether those facilities are trustworthy. A new user (40) entering the computing environment can obtain the log from the trusted computing device in order to ascertain the status of the environment. Alternatively any device can hold data concerning platforms in its vicinity and its operation can be authenticated by the trusted device.

摘要： A method of security monitoring of data files in a computer platform is carried out by a trusted component having a processor and trusted memory area. The method comprises creating one or a plurality of data files in an untrusted memory area of said computing platform, for each created data file, periodically generating a digest data by applying a hash function to each data file, storing the digest data in a trusted memory area and for each file periodically comparing a current digest data of the file with a previously generated digest data of the file. Any differences between a previous and a current digest data indicate that a file in the untrusted memory area has been corrupted.
