    摘要: The present disclosure provides a method for performing modular exponentiation. The method may include generating a first remainder (xp) based on an encrypted message (X) modulo a first prime number (p) and generating a second remainder (xq) based on the encrypted message (X) modulo a second prime number (q). The method may further include generating a third remainder(v1) based on the first remainder (xp) raised to a first private key number (d1) modulo the first prime number (p) and simultaneously generating a fourth remainder (v2) based on the second remainder (xq) raised to a second private key number (d2) modulo the second prime number(q). The method may also include subtracting the fourth remainder (v2) from the third remainder (v1) to yield a result (v1−v2) and multiplying the result (v1−v2) by a constant (c) to produce a second result. The method may additionally include generating a sixth remainder (h) by taking the second result modulo the first prime number (p) and multiplying the sixth remainder (h) by the second prime number (q) to produce a third result. The method may further include adding the third result and the fourth remainder (v2) to yield a final result (Y) and generating, at least in part, a public key based on the final result (Y). Of course, many alternatives, variations and modifications are possible without departing from this embodiment.

    摘要: The present disclosure provides an apparatus and method for generating a Galois-field syndrome. One exemplary method may include loading a first data byte from a first storage device to a first register and loading a second data byte from a second storage device to a second register; ANDing the most significant bit (MSB) of the first data byte and a Galois-field polynomial to generate a first intermediate output; XORing each bit of the first intermediate output with the least significant bits (LSBs) of the first data byte to generate a second intermediate output; MUXing the second intermediate output with each bit of the first data byte to generate a third intermediate output; XORing each bit of the third intermediate output with each bit of the second data byte to generate at a fourth intermediate output; and generating a RAID Q syndrome based on, at least in part, the fourth intermediate output. Of course, many alternatives, variations and modifications are possible without departing from this embodiment.
