Which encryption protocol provides network layer confidentiality?

  • IPsec protocol suite
  • Transport Layer Security
  • Secure Hash Algorithm 1
  • Secure Sockets Layer
  • Keyed MD5
  • Message Digest 5

Explanation: Cryptographic encryption can provide confidentiality at several layers of the OSI model. For example, network layer protocols, such as the IPsec protocol suite, provide network layer confidentiality. Secure Sockets Layer (SSL) or Transport Layer Security (TLS), provide session layer confidentiality. MD5, Keyed MD5, and Secure Hash Algorithm 1 are examples of hash functions. They provide data integrity but not data confidentiality.
