Apparatus and method for modular multiplication and exponentiation based on montgomery multiplication

A system for safe collection of payment by a vehicle operator from riders, the system including a multiplicity of electronic payment receipt generators, each operable by a vehicle operator, wherein each individual one of the payment receipt generators includes an electronic purse storing an amount of electronic cash, each electronic purse including an electronic cash loader operative to use some of the electronic cash to generate a payment receipt to be given by the vehicle operator to a rider, and an electronic purse control unit operative to prevent said electronic cash loader from exceeding said amount of electronic cash, thereby limiting the vehicle operator's entitlement to collect payments from riders, and an electronic cashier purse operative to increment the electronic purse of each electronic payment receipt generator by the amount of payment collected by the vehicle operator to whom the electronic payment receipt generator is assigned.

System for safe collection of payment including electronic payment receipt generators having electronic purses

A modular arithmetic method and microelectronic apparatus therefore, operative to perform a sequence of interleaved Montgomery type multiplications and squaring operations, involves performing a sequence of modular multiplications and squarings using only a single carry save adder. Each multiplication is operative to perform the equivalent of three natural integer multiplication operations using an anticipatory device to determine a Y,value, such that a result is an exponentiation.

Apparatus & method for modular multiplication & exponentiation based on Montgomery multiplication

A compact synchronous microelectronic peripheral machine for standard microprocessors with means for proper clocking and control, has as essential elements: three main subdivided, switched and clocked shift registers, B, S, and N; two only multiplexed serial/parallel multipliers; borrow detectors, ancillary subtractors and adders; delay registers and switching elements; all of which embody a totally integrated concurrent and synchronous process approach to modular multiplication, squaring, and exponentiation. A method for carrying out modular multiplication, wherein the multiplicand A, the multiplier B and the modul, N, comprise m characters of k bits each, the multiplier not being greater than the modulus, is also described, wherein the multiplicand can be much larger than the modulus. It is demonstrated how the device can be used as a large number processor in the normal field of numbers.

A compact synchronous microelectronic peripheral machine for standard microprocessors with means for proper clocking and control, has as essential elements: three main subdivided, switched and docked shift registers, B, S, and N; two only multiplexed serial/parallel multipliers; borrow detectors, ancillary subtractors and adders; delay registers and switching elements; all of which embody a totally integrated concurrent and synchronous process approach to modular multiplication, squaring, and exponentiation. A method for carrying out modular multiplication, wherein the multiplicand A , the multiplier B and the modul, N, comprise m characters of k bits each, the multiplier not being greater than the modulus, is also described, wherein the multiplicand can be much larger than the modulus. It is demonstrated how the device can be used as a large number processor in the normal field of numbers.
