Which of the following protocols is designed to send individual messages securely?
Secure HTTP (S-HTTP) is designed to send individual messages securely. Unlike SSL, which establishes a secure connection between two computers for entire communication sessions, S-HTTP focuses on the encryption of individual HTTP messages or documents. Kerberos is an authentication system, and Secure Electronic Transaction (SET) is a protocol developed for secure credit card transactions. Therefore, the correct protocol for sending individual messages securely is S-HTTP.
Secure HTTP (S-HTTP) was an early standard designed to send individual messages securely. S-HTTP aimed to provide encryption for specific HTTP documents, allowing users to secure particular pages or resources on a website. However, it didn’t gain widespread adoption and was eventually overshadowed by Secure Sockets Layer (SSL) and its successor, Transport Layer Security (TLS). These protocols offer more comprehensive security for entire communication sessions between clients and servers, rather than just individual messages.
