Computer Science (a) Suppose that NAF (non-adjacent form) integer representation of x is used in an algorithm analogous to DOUBLE-AND-(ADD OR SUBTRACT) for computing ax (mod p). Give a pseudo- code of such an algorithm. (b) Explain why such modification doesn't make much sense, while the algorithm DOUBLE-AND-(ADD OR SUBTRACT) is very useful for scalar point multiplication on elliptic curves. (c) Compute NAF of 1023.
