Fragen in diesem Quiz (11)

  1. 1How do modern cryptographers defend against brute-force attacks?
    1. AUse statistical analysis to eliminate the most common encryption keys.
    2. BUse a keyspace large enough that it takes too much money and too much time to conduct a successful attack.
    3. CUse an algorithm that requires the attacker to have both ciphertext and plaintext to conduct a successful attack.
    4. DUse frequency analysis to ensure that the most popular letters used in the language are not used in the cipher message.
  2. 2Which encryption protocol provides network layer confidentiality?
    1. AIPsec protocol suite
    2. BTransport Layer Security
    3. CSecure Hash Algorithm 1
    4. DSecure Sockets Layer
    5. EKeyed MD5
  3. 3Which statement describes asymmetric encryption algorithms?
    1. AThey have key lengths ranging from 80 to 256 bits.
    2. BThey include DES, 3DES, and AES.
    3. CThey are also called shared-secret key algorithms.
    4. DThey are relatively slow because they are based on difficult computational algorithms.
  4. 4Which two non-secret numbers are initially agreed upon when the Diffie-Hellman algorithm is used? (Choose two.)
    1. Abinomial coefficient
    2. Bgenerator
    3. Celliptic curve invariant
    4. Dprime modulus
    5. Etopological index
    6. Fpseudorandom nome
  5. 5In what situation would an asymmetric algorithm most likely be used?
    1. Alogging onto a computer
    2. Bmaking an online purchase
    3. Cuploading a networking book chapter using FTP
    4. Dtransferring a large stream of data between two corporate locations
  6. 6Why is asymmetric algorithm key management simpler than symmetric algorithm key management?
    1. AIt uses fewer bits.
    2. BOnly one key is used.
    3. CTwo public keys are used for the key exchange.
    4. DOne of the keys can be made public.
  7. 7What is the purpose of code signing?
    1. Asource identity secrecy
    2. Bntegrity of source .EXE files
    3. Creliable transfer of data
    4. Ddata encryption
  8. 8Which algorithm can ensure data confidentiality?
    1. AMD5
    2. BPKI
    3. CRSA
    4. DAES
  9. 9What is the purpose of a digital certificate?
    1. AIt guarantees that a website has not been hacked.
    2. BIt authenticates a website and establishes a secure connection to exchange confidential data.
    3. CIt provides proof that data has a traditional signature attached.
    4. DIt ensures that the person who is gaining access to a network device is authorized.
  10. 10Fill in the blank.
