Which of the following protocols supports DES, 3DES, RC2, and RSA2 encryption along with CHAP authentication, but was not widely adopted?
a. S-HTTP
b. S/MIME
c. HTTP
d. PPTP
Answer: A
An alternative to HTTPS is the Secure Hypertext Transport Protocol (S-HTTP), which was developed to support connectivity for banking transactions and other secure web communications. S-HTTP was not adopted by the early web browser developers (for example, Netscape and Microsoft) and so remains less common than the HTTPS standard. Additionally, S-HTTP encrypts individual messages so it cannot be used for VPN security. Answer B is incorrect. S/MIME is used to encrypt electronic mail transmissions over public networks. Answer C is incorrect because HTTP is used for unsecured web-based communications. Answer D is incorrect because Point-to-Point Tunneling Protocol (PPTP) is a network protocol that enables the secure transfer of data from a remote client to a private enterprise server by creating a virtual private network (VPN) across TCP/IP-based data networks.
