Authenticate-then-Encrypt (AtE), or (EtA) (E&A) or (A&E) Discuss the security implications of these choices, which one is recommended and why. Mention important crypto papers (at least one, cite it), in which the security of an important real-life protocol (Hint, the one securely connects your VPN!) refer to this order. Explain why this order matters a lot in practice? You may provide some discussions from these papers (please be brief, just hit on important points).
