In this era, you need to ensure that every message, document or file that you send across the Internet is protected by the highest level of security available. In light of this, many companies are switching over to using public key cryptography as a major part of their overall security program. This type of cryptography is one part of the overall package and while the public key is used to encrypt the information, it requires the private key to decipher the encrypted information and restore it to a readable format.

Public Key Cryptography Sees Wide Use In Online Retail Sites

Because of the algorithm that is used to produce a digital signature, it is possible to create a signature that can readily be verified by both the sender and the receiver. The typically digital signature system actually uses three separate algorithms to ensure that no one can intercept it or create a fake signature. These are the key generation algorithm that chooses one private key from a specific set at random and then sends out both the private and public key.

The Other Two Digital Signature Algorithms Create and Verify

As you look at your corporate web site and realize that your client are going to be using it to contact you with to pay their bills and to exchange other forms of confidential information, you may find that you want to rethink your login in methods and the security they currently offer. If you have been using the standard username / password combination, you might want to consider increasing your security with a single sign on authentication system.

Not Using Single Sign On Authentication Can Leave Your System Vulnerable

When you have to be absolutely positive that the person logging into your secured web site is who they claim to be, you need to consider contacting your certificate authority and asking them to implement a security protocol that includes PKI authentication in order for anyone to log into your site. The reason for this lies along the lines of it being very easy to steal a username / password combination and gain access, but Public Key Infrastructure security is virtually impossible to hack.

PKI Requires More Than a Single Form of Identification

When an X 509 certificate is issued by a certificate authority as a part of your FTP protocols, it contains certain information that is used for several verification purposes. Among these is the public key along with specific information concerning the owner of the certificate. This information can be used to verify the authenticity of the person or company that owns the certificate as well as to prove the authenticity of the certificate.

The X 509 Certificate Also Contains the Private Key

When you run a facility that allows more than one person to access your database, you may find that you have to provide different levels of access to each person and provide safeguards that will stop any unauthorized person from gaining access to areas that they should not be in. Because it is so easy to steal or figure out a username / password combination, you may want to consider using a 2FA authentication system.

The 2FA Provides an Extra Security Measure

The first X 509 certificate was issued in 1988 and uses a hierarchal system that involves the use of verified certificate authorities to issue the actual certificates. When the certificate is issued the binding public key is attached to a specific unique company name, an email address or to a DNS entry. The root certificate for the most common vendors comes preloaded in most browsers so that their SSL certificates are immediately recognized instead of requiring a lengthy identification process.

The X 509 Certificate Provides Secure Access

When you run a large corporation that uses an even larger number of different applications at different levels an in various divisions, it can make things very difficult for members of your IT team to do their work. Given the number of passwords and usernames that they might need to remember in order to access each system when they need to work on them, you may find that switching to a single sign on authentication system for your IT techs might be a better solution.

Single Sign On Authentication Makes Life Easier

The number of people using online bill pay and online banking services has reached astronomical levels. Each of them assumes that every time they use a computer to connect to a business or bank to pay a bill or handle a banking transaction that the site that shows up in their browser is the site they want to be logged into. In order to ensure that this is the case, the first time the real site is accessed a root certificate is placed on the user's computer.

The Root Certificate Verifies Your Digital Certificate

You need to obtain a PKI certificate when you are going to use digital security such as a digital signature or a digital certificate that requires that use of encryption and either single or two form authentication to grant access to encrypted or secured information. This certificate is generally issued by a certificate authority and is issued to allow you to use both a public and private key to protect files, database or any personal identification information that might be entered into a web site such as a payment portal.
