Online Certificate Status Protocol

When certificates become old, outdated, or compromised the web certificate may be revoked. Revoking certificates provides the Internet companies the ability to tell users that they have changed their security certificates. This research will introduce the inherent problem of an outdated certificate revocation system. This research will follow the mixed methods approach and consult many different types of research documents, tests, and discussions. This research will also document the level of knowledge

on the Secure Socket Layer (SSL) protocol originally created by a team at Netscape for secure transactions on early websites (although similar to SSL, TLS is different enough for them to not work together). TLS will create a “tunnel” that is an established connection between source and destination, through which all packet data AND packet headers are encrypted. However, before TLS gets involved, Dubh’s source machine must first establish a reliable transport protocol with which to communicate with

Abstract: Continuous user authentication is a critical prevention-based methodology with protect high security mobile ad-hoc networks (MANETs). Certificate revocation is an important security component in MANETs. A new method to enhance the effectiveness and efficiency of the scheme by employing a threshold based approach to restore a node’s accusation ability and to ensure sufficient normal nodes to accuse malicious nodes in MANETs. The user’s available relevant information on the system, and express

The Fundamentals of SSL Certificates and Certificate Authorities (CA) By adding an SSL certificate, Experts Exchange members not only protect their business but also increase customer confidence by safely encrypting their customers’ most sensitive data. For online transactions, an SSL certificate turns sensitive data into encrypted secure code. The web browser then checks the SSL certificate to make sure that the website is legitimate. Once verified, the web browser and server processes the encoded

The optimal goal is that

network, while a digital certificate is a reference from a neutral company that confirms the identity of an internet site (Shay, 2004, p. 321) and (Tomsho, G., Tittel, E. Johnson, D., 2004, P. 378). The digital certificate is issued by a Certificate Authority (CA) such as Verisign, and a registration authority (RA) that acts as a reference to identify an entity to a user of the website, and uses a directory that holds the certificate and can revoke a company's digital status. The PKI technology is

There are three types of Security breaches in general. They are as follows: 1. Human Error Some security breaches are undoubtedly the direct results of people’s mistakes. Human errors cause most breaches, even if they tend to be far less expensive as compared to the breaches caused by malicious and criminal attacks. These errors include • Mis-delivery of sensitive information to the wrong person by email or fax. • Erroneously making information openly available to the public on a web server or website
