Terms in this set (20)Alice and Bob would like to communicate with each other using a session key but they do not already have a shared secret key. Which algorithm can they use to exchange a secret key? Diffie-Hellman Alice would like to send a message to Bob securely and wishes to encrypt the contents of the message. What key does she use to encrypt this message? Bob's public key What type of function generates the unique value that corresponds to the contents of a message and is used to create a digital signature? Hash What mathematical problem forms the basis of most modern cryptographic algorithms? Factoring large primes Which type of cipher works by rearranging the characters in a message? Transposition Which information security objective allows trusted entities to endorse information? Certification What standard is NOT secure and should never be used on modern wireless networks? Wired Equivalent Privacy (WEP) Bob received a message from Alice that contains a digital signature. What cryptographic key does Bob use to verify the digital signature? Alice's public key Betty receives a ciphertext message from her colleague Tim. What type of function does Betty need to use to read the plaintext message? Decryption What is NOT an effective key distribution method for plaintext encryption keys? Unencrypted email What is NOT a symmetric encryption algorithm? ?

Explanation: Hash functions create a unique, fixed-length output for any given input. This hash value, also known as a message digest, is used to create a digital signature.
What type of cipher replaces bits characters or blocks of information with other bits characters or blocks?Substitution ciphers.
Replace bits, characters, or character blocks in plaintext with alternate bits, characters or character blocks to produce ciphertext. A substitution cipher may be monoalphabetic or polyalphabetic: A single alphabet is used to encrypt the entire plaintext message.
Which algorithm can they use to exchange a secret key?The Diffie-Hellman algorithm will be used to establish a secure communication channel. This channel is used by the systems to exchange a private key. This private key is then used to do symmetric encryption between the two systems.
What standard is not secure and should never be used on modern wireless networks quizlet?What standard is NOT secure and should never be used on modern wireless networks? The Diffie-Hellman (DHE) algorithm is the basis for several common key exchange protocols, including Diffie-Hellman in Ephemeral mode (DHE) and Elliptic Curve DHE (ECDHE).
