- Alice wants to send a secret message, with cleartext message mA, to Kathy, with a method that would provide Kathy with the means to authenticate Alice's message. Alice and Kathy agree on an integer n that results from multiplying two large prime numbers p and q. 1. Considering that RSA encryption is used for this communication, what expression would result from the secret message that Alice sends to Kathy. Assume Alice's public and private keys are ea,da and Kathy's public and private keys are eKdK. hint. The expression should use modular arithmetic 1. Kathy now wants to send Alice a message mK, without the means to provide Kathy with a method to authenticate the message but providing confidentiality. Which of the following would be the expression corresponding to this message? Justify your answer. 1. mkdkmodpm sub k raised to d sub k in modulo p 2. mkekmodpm sub k raised to e sub k in modulo p 3. mkeamodnm sub k raised to e sub a in modulo n 4. mknmodp - m sub k raised to n sub k in modulo p 5. mknmodekm sub k raised to n in modulo e sub k 6. mkdkmodnm sub k raised to d sub k in modulo n 7. mkdkmodqm sub k raised to d sub k in modulo q 2. What potential attack an eavesdropper, Peter, could use if he is able to intercept the communication from Kathy to Alice? Explain how this attack can take place
