Which of the following statements is TRUE about electric signatures?
Jenny W.
Question: Ideally, a valid encryption scheme should have the following properties: A. Source: If intercepted, hard to decode B. Easy to encrypt C. Hard to transmit D. Easy for recipient to decode E. Source of the message should be impossible to validate Question: Select all TRUE about digital signatures: A. It depends on the message B. It depends on the user's usual (ink) signature C. Should be verified with private key D. Signed with private key E. Digital signature depends on a random number that is different each time Question: Select all TRUE of both RSA and ECDSA. A. They are digital signature algorithms B. They use public and private keys C. They protect against authentication/verification of messages D. They are of equal strength E. The public key is used to sign

A sender S sends a document P to a receiver R. The sender also generates a digest: d = H(P), and encrypts d to obtain a digital signature, sig, for P. E/D are the encryption/decryption functions. K-S-pub/K-S-pri are the public/private keys of S. K-R-pub/K-R-pri are the public/private keys of R. To verify that P is genuine, the receiver R will have to compute the following values (check all that apply): H(P) H(sig) D(P, K-S-pub) D(sig, K-S-pub) D(sig, K-R-pub) D(sig, K-R-pri) E(d, K-R-pri) E(d, K-S-pub)
