Questions in this quiz (11)
1How do modern cryptographers defend against brute-force attacks?
- AUse statistical analysis to eliminate the most common encryption keys.
- BUse a keyspace large enough that it takes too much money and too much time to conduct a successful attack.
- CUse an algorithm that requires the attacker to have both ciphertext and plaintext to conduct a successful attack.
- DUse frequency analysis to ensure that the most popular letters used in the language are not used in the cipher message.
2Which encryption protocol provides network layer confidentiality?
- AIPsec protocol suite
- BTransport Layer Security
- CSecure Hash Algorithm 1
- DSecure Sockets Layer
- EKeyed MD5
3Which statement describes asymmetric encryption algorithms?
- AThey have key lengths ranging from 80 to 256 bits.
- BThey include DES, 3DES, and AES.
- CThey are also called shared-secret key algorithms.
- DThey are relatively slow because they are based on difficult computational algorithms.
4Which two non-secret numbers are initially agreed upon when the Diffie-Hellman algorithm is used? (Choose two.)
- Abinomial coefficient
- Bgenerator
- Celliptic curve invariant
- Dprime modulus
- Etopological index
- Fpseudorandom nome
5In what situation would an asymmetric algorithm most likely be used?
- Alogging onto a computer
- Bmaking an online purchase
- Cuploading a networking book chapter using FTP
- Dtransferring a large stream of data between two corporate locations
6Why is asymmetric algorithm key management simpler than symmetric algorithm key management?
- AIt uses fewer bits.
- BOnly one key is used.
- CTwo public keys are used for the key exchange.
- DOne of the keys can be made public.
7What is the purpose of code signing?
- Asource identity secrecy
- Bntegrity of source .EXE files
- Creliable transfer of data
- Ddata encryption
8Which algorithm can ensure data confidentiality?
- AMD5
- BPKI
- CRSA
- DAES
9What is the purpose of a digital certificate?
- AIt guarantees that a website has not been hacked.
- BIt authenticates a website and establishes a secure connection to exchange confidential data.
- CIt provides proof that data has a traditional signature attached.
- DIt ensures that the person who is gaining access to a network device is authorized.
