摘要： Various embodiments of the present invention relate to a point-of-sale (POS) system, and more particularly, to systems, devices and methods of making secure payments using a mobile device in addition to a POS terminal that may be an insecure payment device exposed to various tamper attempts under certain circumstances. The mobile device is involved in a trusted transaction between a central financial entity, e.g., a bank, and the payment terminal, such that the insecure payment terminal may be further authenticated based on rolling codes, two-way or three-way authentication, or an off-line mode enabled by incorporation of the mobile device. Although either of the mobile device and the payment terminal provides limited security, a POS system incorporating both of them demonstrates an enhanced level of security.

摘要： Presented are systems and methods that allow hardware designers to protect valuable IP and information in the hardware domain in order to increase overall system security. In various embodiments of the invention this is accomplished by configuring logic gates of existing logic circuitry based on a key input. In certain embodiments, a logic function provides results that are dependent not only on input values but also on an encrypted logic key that determines connections for a given logic building block, such that the functionality of the logic function cannot be determined by reverse engineering. In some embodiments, the logic key is created by decrypting a piece of data using a secret or private key. Advantages of automatic encryption include that existing circuitry need not be re-implemented or re-built, and that the systems and methods presented are backward compatible with standard manufacturing tools.

摘要： The invention relates to semiconductor devices, and more particularly, to systems, devices and methods of utilizing inherent differences among physical elements in an electrical component to generate unique and non-duplicable numbers that are statistically random and repeatable. These bits may be applied as identifications, random number seeds or encryption keys in many security applications, e.g., a financial terminal. An integrator is coupled to a plurality of physical elements, selects two physical elements or element sets, and generates an integrated difference signal according to a difference between these two physical elements or element sets. A comparison-decision logic further determines whether the difference between the selected two physical elements is associated with a bit of “1” or “0”. In some embodiments, a multi-bit number constitutes multiple bits each of which may be derived from a difference between two randomly selected physical elements or element sets.

摘要： An energy-efficient sequencer comprising inline multipliers and adders causes a read source that contains matching values to output an enable signal to enable a data item prior to using a multiplier to multiply the data item with a weight to obtain a product for use in a matrix-multiplication in hardware. A second enable signal causes the output to be written to the data item.

摘要： Various embodiments of the invention allow to protect data in a logic circuit from being detected by commonly known observation methods. In certain embodiments, this is accomplished by selecting a set of reconfigurable logic blocks within the logic circuit to form a routing path in such a manner that the circuit performs a given function while making it virtually impossible to follow data through the circuit as the data is being processed. The routing path may be selected in a random or pseudorandom fashion, for example, in response to detecting an environmental change. In some embodiments, known data is injected into the logic path and the output is compared to a known value. If the result is incorrect, for example, because a section of the hardware ceased to properly perform due to a faulty circuit component, signals are routed through an operational part of the circuit to provide a different and valid logic path, while avoiding faulty logic gates.
