Abstract: Method and device for verifying the security of a computing platform. In the method for verifying the security of a computing platform a verification machine is first transmitting a verification request via an integrity verification component to the platform. Then the platform is generating by means of a trusted platform module a verification result depending on binaries loaded on the platform, and is transmitting it to the integrity verification component. Afterwards, the integrity verification component is determining with the received verification result the security properties of the platform and transmits them to the verification machine. Finally, the verification machine is determining whether the determined security properties comply with desired security properties.

Abstract: Systems, apparatus and methods for privacy-protecting integrity attestation of a computing platform. An example method for privacy-protecting integrity attestation of a computing platform (P) has a trusted platform module (TPM), and comprises the following steps. First, the computing platform (P) receives configuration values (PCR1 . . . PCRn). Then, by means of the trusted platform module (TPM), a configuration value (PCRp) is determined which depends on the configuration of the computing platform (P). In a further step the configuration value (PCRp) is signed by means of the trusted platform module. Finally, in the event that the configuration value (PCRp) is one of the received configuration values (PCR1 . . . PCRn), the computing platform (P) proves to a verifier (V) that it knows the signature (sign(PCRp)) on one of the received configuration values (PCR1 . . . PCRn).

Abstract: The invention provides a data network, systems and methods for checking nodes of a data network that are used for detecting whether a privacy policy concerning an information is maintained. The information comprises a mark corresponding to the privacy policy. The mark defines the storage place or the accessing paths or the transferring paths of the information. The mark is automatically searchable. The mark is searched, analyzed and checked as to whether the privacy policy is maintained. The advantage of the system is that vulnerabilities of systems for protecting confidential information may be detected a long time before an attack on the confidential information occurs.

Abstract: A data access control facility is implemented by assigning personally identifying information (PII) classification labels to PII data objects, with each PII data object having one PII classification label assigned thereto. The control facility further includes at least one PII purpose serving function set (PSFS) comprising a list of application functions that read or write PII data objects. Each PII PSFS is also assigned a PII classification label. A PII data object is accessible via an application function of a PII PSFS having a PII classification label that is identical to or dominant of the PII classification label of the PII object. A user of the control facility is assigned a PII clearance set which contains a list of at least one PII classification label, which is employed in determining whether the user is entitled to access a particular function.

For that a method and system are presented for providing an identity-related information about a user to a requesting entity. The method comprises a location-request step initiated by the requesting entity for requesting from a client application a location information that corresponds to a location entity possessing the identity-related information, a redirecting step for connecting the client application to the location entity in order to instruct the location entity to transfer the identity-related information to the requesting entity, and an acquiring step for obtaining the identity-related information.

Abstract: The invention is related to a system which allows a user to authenticate unknown terminals. The invention uses a first authentication step wherein the terminal authenticates itself to a server. Depending on whether the personal device has its own output means, such as a loudspeaker or a screen, the final message, whether the terminal can be trusted or not, can be output on the personal device or on the terminal itself. In the case where the device has no output means of its own, this message can originate in the device and be transmitted from there to the terminal. The user can input authentication information into his personal device, which can then be fully or partially transmitted to the terminal. In the end, the terminal may use the transmitted information to give out the authenticity output message. After the first authentication step follows a second authentication step, wherein the server authenticates itself to the personal device, if there is one.

Abstract: The present invention relates to a method and corresponding system for the computerized processing of documents with electronic signatures. For providing an electronically signed document to an exploiter the current invention suggests a first step of transforming a signer machine-readable source format of the document into a universal format representing said document identically and independently from a computer system used for its representation. In a second step the electronic signature is created based on the universal format of the document. Finally in a third step the electronic signature and a single representation of the document in an exchange format is provided to an exploiter. For further processing of the electronically signed document by an exploiter it is suggested to validate the electronic signature by transforming the exchange format of the document into the universal format of the document and validating said signature with respect to said universal format of the document.

Abstract: A method and a system for providing an anonymous access to a service within a network is disclosed. Thereby a user entity sends a user request comprising access-service information and requested service information to an anonymous-access service. The anonymous-access service verifies whether the access-service information are valid. In the event that the access-service information are valid, the anonymous-access service assigns the access-service information to subscription information and connects to the service by sending a verified request comprising the subscription information and the requested service information. The anonymous-access service receives response-service information from the service and forwards it to the user entity. By doing so, the user's instances of access to the services are not linkable to each other nor are they linkable to the user's real identity.
