AND VERIFIED ANSWERS GRADED A+
⩥ The most widely used asymmetric encryption algorithm is what?
+Caesar Cipher
+Vigenere
+RSA
+DES. Answer: RSA
The RSA encryption algorithm is one of the most widely used public
key encryption algorithms that have ever been invented. It was created
by the three scientists Ronald Rivest, Adi Shamir, and Leonard Adleman
in 1977, and today it is increasingly being used in the network area.
⩥ Original, unencrypted information is referred to as ____.
+text
+plaintext
+cleantext
,+ciphertext. Answer: Plaintext
Plaintext is a term used in cryptography that refers to a message before
encryption or after decryption. That is, it is a message in a form that is
easily readable by humans. Encryption is the process of obscuring
messages to make them unreadable in the absence special knowledge
⩥ Which of the following is not an asymmetric system?
+SSL
+DES
+PGP
+RSA. Answer: DES
The Data Encryption Standard is a symmetric-key algorithm for the
encryption of electronic data. Although now considered insecure, it was
highly influential in the advancement of modern cryptography.
⩥ In order for User A to send User B an encrypted message that only
User B can read, User A must encrypt message with which of the
following keys?
, +User B's public key
+User B's private key
+User A's public key
+User A's private key. Answer: USER B's Public Key
Public key cryptography, or asymmetrical cryptography, is any
cryptographic system that uses pairs of keys: public keys which may be
disseminated widely, and private keys which are known only to the
owner
⩥ The greatest weakness with symmetric algorithms is _____.
+The problem of key exchange
+The problem of generating keys
+They are slower than asymmetric
+They are less secure than asymmetric. Answer: The Problem of Key
exchange
The biggest problem with symmetric key encryption is that you need to
have a way to get the key to the party with whom you are sharing data.
⩥ Which of the following is generally true about block sizes?
