摘要： A method and system for encrypting input data may include receiving an input point and a randomness rate and generating a random selection value and a random position value from the randomness rate. At least one of the input point and points encrypted by performing elliptic curve (EC) operation over a plurality of rounds may be randomly selected based on the randomness rate and the random position value. The selected point may be converted to a point representation directed by the random selection value. A finally encrypted output point may be generated by performing the EC operation over a plurality of rounds based on the input point and a secret key.

摘要： In a Montgomery multiplier, a modulus product generator may select a modulus product from a plurality of selectable n-bit modulus numbers M, a given modulus number M being formed from a currently input extended chunk of bits among the n-bit modulus numbers. A partial product generator may select a multiplicand number from a plurality of selectable n-bit multiplicands A as a partial product, a given multiplicand A being formed from a currently input extended chunk of bits among the n-bit multiplicands. An accumulator may accumulate the selected modulus product and partial product to generate a multiplication result. The Montgomery multiplier may be part of an operation unit that may include a memory and host, and may be adapted to perform a Montgomery multiplication operation and a normal multiplication operation based on a logic state of a control signal input thereto.

摘要： A method for power reduction and increasing computation speed for a Montgomery modulus multiplication module for performing modulus multiplication. A coding scheme reduces the hamming distance for partial product and multiple modulus selection, reducing MUX operations and power consumption. Synchronization registers synchronize partial product and multiple modulus values input to an accumulator reducing glitch and/or increase computation speed. Registers provide storage of previous values and reduce the need to obtain the values from a MUX, reducing MUX operations and/or reducing power consumption.
