Assume computer A is sending a message to computer B using public key crypto, with function g(K, T) where K is a key and T is text or ciphertext. The private and public keys of each computer are as follows: Private Key of A = ka; Private Key of B = kb; Public Key of A = KA; Public Key of B = KB.

Use the following predefined terminology: Cab = Cyphertext from a to b, Sab = Signature produced by a to be verified by b; Cba = Cyphertext from b to a, Sba = Signature produced by b to be verified by a.

Fill the following table indicating how messages from each computer to another will be signed and such signature verified:

Message	Signed	Signature Verification
A-to-B
B-to-A
