Which of the following ensures confidentiality of information sent over the internet?

  • Digital signature
  • Digital certificate
  • Online Certificate Status Protocol
  • Private key cryptosystem 
Explanation: 
Confidentiality is assured by a private key cryptosystem. Digital signatures assure data integrity, authentication and nonrepudiation, but not confidentially. A digital certificate is a certificate that uses a digital signature to bind together a public key with an identity; therefore, it does not address confidentiality. Online Certificate Status Protocol (OCSP) is an Internet protocol used for obtaining the revocation status of a digital certificate.
