SHTTP stands for which of the following ?

A Slow Hyper Text Transfer protocol

B Smooth Hyper Text Transmission Protocol

C Secure Hyper Text Transmission Protocol

D Secure Hyper Text Transfer Protocol

E None of these

Correct Answer: Option D

Solution:

S-HTTP (Secure Hypertext Transfer Protocol or Secure HTTP) is an extension to the Hypertext Transfer Protocol (HTTP) that

allows the secure exchange of files on the Would Wide Web. Each S-HTTP file is either encrypted, contains a digital certificate,

or both. For a given document, S-HTTP is an alternative to another well-known security Protocol, Secure Sockets Layer (SSL). A

major difference is that S-HTTP allows the client to send a certificate to authenticate the user whereas, using SSL, only the server can

be authenticated. S-HTTP is more likely to be used in situations where the server represents a bank and requires authentication from the

user that is more secure than a userid and password.
