The brachialis muscle has attachments to the anterior portion of the distal half of the humerus and the anterior portion of the proximal ulna.  The main action of the brachialis muscle is forearm or elbow flexion.  Knowing this you can deduce that the ______________ occurs at the more stable, humerus part with the ____________ being at the more mobile ulnar attachment.

Problem 2 (20 points). You are asked to recommend a specific way a sender can send a large file to a receiver with his secret-public key pair, without interaction. I.e., you cannot use interactive key exchange protocols. The receiver’s public key is assumed to be authentic. The sender doesn’t have her own key pair. In addition to the strongest security you are asked to pay attention to efficiency of your suggested scheme. 1) Describe what does to send and what does to get . To do so, use the known schemes and their algorithms as building blocks. E.g., if you use AES-CBC$ as a building block, do not define it, just refer to its algorithms. 2) Specify what security level your scheme provide, under which assumptions, and why. You can refer to the known notions of security and the results we studied in class. It is OK to rely on the random oracle model if needed.
