摘要： The present invention relates to a cryptographic block identification apparatus which, in order to analyze encryption logic used by malware to conceal communication, identifies a cryptographic block where encryption logic is stored within a program of the malware. The cryptographic block identification apparatus includes a block candidate extraction part and a cryptographic block identification part. The block candidate extraction part analyzes an execution trace in which an execution step of malware is recorded, calculates an evaluation value representing cipher likeliness of the execution step based on whether or not an operation type that characterizes cipher likeliness of the execution step is included in the execution step, and extracts an execution step where the evaluation value exceeds a threshold L, as a block candidate which is a candidate of a cryptographic block. The cryptographic block identification part identifies a region of the execution trace in which the block candidates are consecutive beyond a threshold M, as a cryptographic block.

摘要： Provided is an on-chip monitor circuit mounted on a semiconductor chip that is equipped with a security function module for performing a security function process on an input signal and outputting a security function signal, the on-chip monitor circuit comprising a monitor circuit for monitoring signal waveforms of the semiconductor chip, wherein the circuit is provided with a first storage means for storing data that designates a window period in which to perform a test of the semiconductor chip, and a control means for performing control to operate the circuit during the window period, when a prescribed test signal is inputted to the security function module. By using the on-chip monitor circuit in a semiconductor chip of which security is required, security attacks, e.g., a Trojan horse or the like, intended to embed a malicious circuit in the production stage of security function module-equipped semiconductors chips, can be prevented.

摘要： To provide for a physical security mechanism that forms a complete envelope of protection around the cryptographic module to detect and respond to an unauthorized attempt at physical access, a tamper sensing encapsulant generally encapsulates the cryptographic module. The tamper sensing encapsulant includes a first shape actuation layer associated with an electrically conductive first trace element and a second shape actuation layer associated with an electrically conductive second trace element. The first shape actuation layer is positioned against the second shape actuation layer such that the first trace element and the second trace element do not physically touch at an operating temperature of the cryptographic module and do physically touch when the first shape actuation layer and the second shape actuation layer are thermally loaded. Upon first trace element and the second trace element touching, a circuit is formed that disables the cryptographic module.

摘要： Apparatuses, methods, and systems pertaining to the verification of portable consumer devices are disclosed. In one implementation, a verification token is communicatively coupled to a computer by a USB connection so as to use the computer's networking facilities. The verification token reads identification information from a user's portable consumer device (e.g., credit card) and sends the information to a validation entry over a communications network using the computer's networking facilities. The validation entity applies one or more validation tests to the information that it receives from the verification token. If a selected number of tests are passed, the validation entity sends a device verification value to the verification token, and optionally to a payment processing network. The verification token may enter the device verification value into a CVV field of a web page appearing on the computer's display, or may display the value to the user using the computer's display.
