E. | Here is another weakness of affine ciphers (a) Suppose

E. | Here is another weakness of affine ciphers (a) Suppose Alice and Bob are using an affine cipher x ? ax + b in which A gets encrypted to the letter corresponding to the number yo and B gets encrypted to the letter corresponding to yi. Use this information to determine the key (a, b). (b) Suppose the affine cipher encrypts AH Y and B D. Decrypt the message FSN E. | Here is another weakness of affine ciphers (a) Suppose Alice and Bob are using an affine cipher x ? ax + b in which A gets encrypted to the letter corresponding to the number yo and B gets encrypted to the letter corresponding to yi.
