A. For an encryption algorithm (such as RSA), is it important to keep the algorithm secret, the key secret, or both? (2 points) B. Adam and Eve are in the mood to communicate, albeit electronically Even in those early days, RSA cryptography and MDS hashing schemes have beer sveloped. Adam has a private key denoted as Kp and a public key denoted as KpSimilarly, Eve has a private key Knsu and a public key KpB The following notation is used in this problem E(m, k) denotes message m is encrypted with key k S(m, k) denotes message m is signed with key k Dm, R, denotes that a message m is decrypted with key k MDS(m), denotes the result when the MD5 hash is applied on message m. For each of the parts, fill in the blanks with the appropriate answer to correctly complete the statements made in that part.[4+4+8+4 Adam wants to send a message M so that Eve can read it and no one else can. Then, he must send the message Mont-E(M,-- Adam wants to sign a message M so that Eve can verify that Adam has sent it. Then, Adam generates a signature of message M as (i) (ii) Adam wants to be more efficient and combine MDS hashing with public key cryptography. He should then generate a signature (i) Instead of signing on the entire message M (as in part() above) Eve receives message M from Adam which has been signed as in part (ii). The key that Eve needs to veritfy the signature is (iv)
