The invention relates to an electronic device for cryptographic processing, having at least two electronic circuits (IC, CC, CP) coupled via a connection means, wherein the connection means is arranged for transferring data signals between the two electronic circuits. The electronic device further has a monitoring circuit (401) arranged to monitor a deviation in the capacitance of the connection means. In case the deviation exceeds a predetermined value an alert signal (411) is generated.

The present invention discloses a method for using a relational database management system to support on-line analytical processing (OLAP) systems by providing a security access mechanism. The method of restricting access to data contained in a business intelligence system, comprises the steps of defining one or more security roles, associating the security roles with business intelligence data, selecting one or more security roles from the one or more security roles, combining the one or more s...

The present application relates generally to content management (e.g., management of audio, video and/or imagery). One claim recites a method including: tracking up to N identifiers associated with previously accessed content items, where N is an integer, and where each previously accessed content item has an identifier associated therewith; reviewing rendering rules associated with a new content item or with an identifier associated with the new content item; and restricting access to the new c...

Exemplary embodiments disclosed herein may include a method and system for providing information to a user and safely disclosing identity information over the Internet comprising receiving information from a server, analyzing the information, presenting the analyzed information to a user for validation in a finite number of configurations controlled by a client, and validating of the information by the user.

A credential provisioning technique is provided that is secure yet easy to administer. A credential provisioner such as a network AP is configured to leave a secure mode of operation and allow open authentication with a wireless supplicant. After open authentication is established, the wireless supplicant requests credential provisioning. In response, the credential provisioner supplies the supplicant with an encrypted password. To prevent unauthorized access, the supplicant again requests crede...

In an arrangement allowing remote maintenance of a computer-controlled system to be serviced, in particular a medical system, the maintenance occurs via a spatially independent monitoring system in communication with the system to be serviced. The system to be serviced is, among other things, designed for the processing of access-protected data such as, for example, patient data. Access to the access-protected data by the monitoring ensues exclusively via an authorization unit associated with th...

A security component determines whether a request for a resource poses a security risk to a computing device and verifies the integrity of the requested resource before the request is allowed. For a request having arguments and a resource path with a filename that identifies the resource, the security component determines that the request does not pose a security risk if the resource path does not exceed a maximum number of characters, individual arguments do not exceed a maximum number of chara...

The present invention discloses an improved information security system and method. A polymorphic engine is used to enhance the security features of a software application and the data generated by or made available to the application and/or the operating system. The polymorphic engine operates to randomly alter the standard executable code of the original application while preserving its functional characteristics. Each polymorphed instance of the application differs from any other instance of ...

A copyright protection system includes a recording device and a reproduction device. The recording device writes encrypted content, an encrypted content key for decrypting the encrypted content, and license information on a recording medium on which a unique media number has been recorded in an unrewritable state. The license information is generated using both the media number and the encrypted content key, and therefore reflects both values. The reproduction device reads the media number, the ...

Disclosed is a network hardening mechanism. The mechanism: generates a dependency graph from a multitude of exploits; constructs a goal conditions expression which may then be used to determine set(s) of safe network configurations. A subset of these safe network configuration sets may then be selected for implementation using hardening costs as a criterion.
