A transaction system for use with passive data storage media, such as optical memory cards, uses secure protocols involving digital certificates for communication between a read / write drive and the medium and also for communication between the drive and a host computer. The drive is physically secured with tamper resistant features and stores cryptographic keys and firmware for executing the secure protocols. All messages (data or commands) passed between the drive and the passive medium or host computer not only are encrypted but also include at least one digital certificate for authenticating the message. Typically, asymmetric (public-private key) encryption is used and keys may be derived from an authorized user's password, personal identification number, or biometric data. The drive includes sensors to detect any attempted intrusions and a control unit that will destroy the critical information (keys and protocol code) in response to a detected intrusion. The keys and protocols stored in a drive can themselves be changed through appropriate use of a secure protocol involving digital certificates.

This invention enables to achieve significant reduction or even to eliminate friction at certain critical interfaces between the contact mechanism components, thus, reducing or potentially eliminating hysteresis, and improving performance consistency, and also eliminating mechanism performance dependency on wear level and condition of an intermediate cam surface. An additional feature of this invention is a reduction of a loss of contact torque / force during over-travel in the ON position when the fixed and / or moveable contacts erode. Configurations described in this invention may also feature physical protection for the moving components of the contact mechanism assembly from flying particles resulting from short circuit shots.

The invention provides a method for designing a high-safety chip active shielding physical protection structure. The chip active physical protection structure has the function that a high-safety chip is prevented from being attacked in an intrusive mode, for example the high-safety chip is tampered or detected in a physical mode. Single-layer metal wires are active shielding wires and the active shielding wires are fully distributed on the surface of the chip.

If patterns designed according to the smallest rule are fully distributed on the chip, the possibility that the chip circuit functional performance failure caused by particle contamination is increased. In order to reduce the volume production chip circuit failure, the width and / or the spacing of the active shielding wires are / is usually widened. If the size of each active shielding wire is widened, the safety of the chip can be reduced. In order to solve the problem of the contradiction between the safety of the chip and the yield of the volume production products, the pitch-variable active shielding physical production structure is further provided, so that dual-improvement in the safety and the yield of the chip products is achieved.

The decrypted content bitstream is physically protected from access. Furthermore, the analog information can be watermarked such that re-digitizing the analog information would produce a traceable watermarked copy of the content.
