摘要： Described are context-aware low-power systems and methods that reduce power consumption in compute circuits such as commonly available machine learning hardware accelerators that carry out a large number of arithmetic operations when performing convolution operations and related computations. Various embodiments exploit the fact that power demand for a series of computation steps and many other functions a hardware accelerator performs is highly deterministic, thus, allowing for energy needs to be anticipated or even calculated to a certain degree. Accordingly, power supply output may be optimized according to actual energy needs of compute circuits. In certain embodiments this is accomplished by proactively and dynamically adjusting power-related parameters according to high-power and low-power operations to benefit a machine learning circuit and to avoid wasting valuable power resources, especially in embedded computing systems.

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： 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 decryption 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： 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： The invention relates to a smartcard reader, and more particularly, to systems, devices and methods of creating a card input/output interface that allows the smartcard reader to couple to a smartcard within a secure cavity. The secure cavity is mounted on an internal side of a system housing, i.e., a smartcard socket, included in the smartcard reader. An interface chip is further attached inside the secure cavity. When the smartcard is inserted to a designated position or depth inside the system housing, the secure cavity encloses the interface chip and its contact area with the smartcard. Mechanical contacts on the interface chip are thus aligned to and physically contact electrical connectors on the inserted smartcard, so as to electrically couple the interface chip and the smartcard. As a result, sensitive data within the smartcard may be protected from exposure to any tamper attempt and processed with an enhanced security level.

摘要： The invention relates to a secure device, and more particularly, to systems, devices and methods of reducing power consumption of the secure device by limiting the amount of secure volatile memory that needs to be supplied by a battery. In a transport power mode, a sensitive data originally stored in a volatile memory is backed up in an encrypted format to a non-volatile memory, such that none or only a small area of the secure volatile memory has to be retained and powered by the battery for preserving cryptographic keys that are used to backup and recover the sensitive data. This secure device is applied in high security applications such as secure financial terminals.

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.
