Im a first year Mathematics student and we've been given this coursework to do for the module Numbers, Groups and Codes. We are using the computer software Maple. I don't know where to start! Any help?
A public key code has base n = 564146777 and encoding exponent
a = 282044381.
(i) Factorise n and calculate (n).
(ii) Calculate the decoding exponent x (i.e. a?1 mod (n)).
(iii) Decode the following received message using the letter to number equivalents
in the attached table (p.4). Each block corresponds to a sequence of two letters; thus,
since 10 corresponds to A and 11 to B, 1011 stands for AB etc.
