Terms in this set (20)Which areas of a file cannot be used by steganography to hide data? in the directory structure of the file system Egor wanted to use a digital signature. Which of the following benefits will the digital signature not provide? verify the receiver Alexei was given a key to a substitution cipher. The key showed that the entire alphabet was rotated 13 steps. What type of cipher is this? ROT13 What is the latest version of the Secure Hash Algorithm? SHA-3 What is a characteristic of the Trusted Platform Module (TPM)? It provides cryptographic services in hardware instead of software Proving that a user sent an email message is known as _____. non-repudiation Which of these is the strongest symmetric cryptographic algorithm? Advanced Encryption Standard Which of the following key exchanges uses the same keys each time? Diffie-Hellman (DH) If Bob wants to send a secure message to Alice using an asymmetric cryptographic algorithm, which key does he use to encrypt the message? Alice's public key The Hashed Message Authentication Code (HMAC) _____. hashes the key and the message A(n) _____ is not decrypted but is only used for comparison purposes. digest What is data called that is to be encrypted by inputting it into a cryptographic algorithm? plaintext Illya was asked to recommend the most secure asymmetric cryptographic algorithm to his supervisor. Which of the following did he choose? RSA Abram was asked to explain to one of his coworkers the XOR cipher. He showed his coworker an example of adding two bits, 1 and 1. What is the result of this sum? 0 Which of these is NOT a characteristic of a secure hash algorithm? Collisions should be rare. Which of these has an onboard key generator and key storage facility, as well as accelerated symmetric and asymmetric encryption, and can back up sensitive material in encrypted form? Hardware Security Module (HSM) Which of these is NOT a basic security protection for information that cryptography can provide? risk loss At a staff meeting one of the technicians suggested that the enterprise protect its new web server by hiding it and not telling anyone where it is located. Iosif raised his hand and said that security through obscurity was a poor idea. Why did he say that? It would be essentially impossible to keep its location a secret from everyone. Alyosha was explaining to a friend the importance of protecting a cryptographic key from cryptoanalysis. He said that the key should not relate in a simple way to the cipher text. Which protection is Alyosha describing? confusion Public key systems that generate random public keys that are different for each session are called _____. perfect forward secrecy Recommended textbook solutions

True or False. 4 answers Which key is used for asymmetric encryption?Asymmetric encryption is also called public key encryption, but it actually relies on a key pair. Two mathematically related keys, one called the public key and another called the private key, are generated to be used together. The private key is never shared; it is kept secret and is used only by its owner.
When Alice encrypts a message using her private key before sending it to Bob What will Bob need to decrypt Alice's message?If Bob wants to send Alice a secret message, he encrypts it with Alice's public key. Then no one but Alice can decrypt it. Only her private key can undo the encryption, and no one can figure out the private key from the public key.
Which cryptographic method should Susanne use to ensure that a document can be encrypted with a key and decrypted with a different key quizlet?Use: Susan's public key (The message should be encrypted with Susan's key for her to decrypt and read with her private key). Use: Bob's private key. (Bob's private key is used to encrypt the hash. Most common asymmetric cryptography algorithm.
What is Alice's private key?Alice has both a public key and a private key, so she keeps her private key in a safe place and sends her public key to Bob. Bob encrypts the secret message to Alice using Alice's public key. Alice can later decrypt the message with her private key.
