Cryptography and Information Security

The security of information is upheld by several methods and mechanisms that are embedded into the security architecture of information systems and modern communication infrastructure. Cryptography has been known to be one of the information security mechanisms that makes it possible to hide the information that is held in any communication thus making it possible to not only communicate securely but also be confidential whenever moving information over a network. The media files and other types of information that are being passed over a network will tend to require a form of protection that will not only prevent detection, but keep the network running without interruptions or interceptions.

Modern information systems have been known to work wonders in producing codes and encryption sequences that are very hard for attackers to track. This makes sure that the security of the information is maintained and all the information and data that passes over a network gets to be encoded into a secure form before it can be passed over the network. The security of the information also gets to be maintained whenever the cryptography makes use of adequate enough key lengths which will not only be useful to preventing the hackers from revealing its contents, but also adds to the time that a hacker will spend trying to find out what is within a piece of communication that has been intercepted on the internet.

Cryptography has been in use by traditional computer scientists and physicists for a long time and has been backed by mathematicians who have been able to assist in the development of algorithms that totally obfuscate the information that is intended for a recipient before it even leaves the application that is being used in the communication. In some instances, the message will not be passed across unless both the devices that are communicating are turned on, connected to a network and have the communication program opened. Some of the communication will also not pass across when the receiving device does not have an active connection. This makes sure that nothing gets intercepted on the way and the users of the communication will be assured that nothing that passes between them can be stolen while it is still en-route.

Communication is getting safer and safer with information being turned into formats that cannot be understood. For instance, one can be able to send an image or a file over the internet and have the image contain another file. The file format can also be modified to pass the file off as something else which will not be noticed by the applications that are tasked with preventing these files from crossing networks. In this way, the users of the network are able to communicate securely without having to get into any trouble or lose the confidentiality of their information.
