Abstract: A method and apparatus for fast electronic self-destruction of a CMOS integrated circuit. The present invention electrically destroys devices containing semiconductor components, securing the components from inspection by detecting the initiation of an attempt to inspect the component and, responsive thereto, electrically destroying the component. In some embodiments of the present invention, a switcheable pad having a destruct state and an operating state is connected to a well or to the substrate of the semiconductor device. When in destruct state, the switcheable pad drives the voltage of the well or substrate to a voltage that induces latch-up of the semiconductor device, allowing very large currents to flow through active or passive elements fabricated on the surface of the semiconductor device.

Abstract: A system and method for preventing a copy of a document to the output from a printing node until the printing node authenticates the intended recipient. The system includes a sending node, a printing node and a communication link coupling these nodes together in a network fashion. The sending node has access to a public key of the printing node and uses this public key to encrypt a header and document before transmission to the printing node over the communication link. The priority node has access to its private key to decrypt the header to ascertain whether the document requires authentication by the intended recipient before being output.

Abstract: An integrated circuit component for enforcing licensing restrictions. Such enforcement is performed through remote transmission of access privileges for executing a licensed program from the integrated circuit component to another similar component. The integrated circuit component comprising a non-volatile memory for storing a uniquely designated key pair, an authentication device certificate and a manufacturer public key along with cryptographic algorithms, a processor for executing the cryptographic algorithms in order to process information inputted into the integrated circuit component and for transmitting the processed information into volatile memory and a random number generator for generating the uniquely designated key pair internally within the integrated circuit component.

Abstract: A semiconductor device for storing encryption/decryption keys at manufacture in combination with digital certificates to ensure secured communications between the semiconductor device and another device. The semiconductor device comprising a non-volatile memory for storing the encryption/decryption keys and at least one digital certificate, internal memory for temporarily storing information input into the semiconductor device from the other device and possibly encryption and decryption algorithms, a processor for processing the information and a random number generator for generating the encryption/decryption keys completely internal to the hardware agent.
