In one of my previous articles, I touched upon the basics of VoIP security. Recently I came across this YouTube video covering a seminar given by Phillip Zimmermann (the Father of PGP) talking about VoIP encryption for the Stanford University Computer Systems Colloquium. Basically, Zimmermann talks about ephemeral encryption of VoIP traffic using Diffie-Hellman key [...]
Technical Introduction from TrueCrypt.org
TrueCrypt is a software system for establishing and maintaining an on-the-fly-encrypted volume (data storage device). On-the-fly encryption means that data is automatically encrypted or decrypted right before it is loaded or saved, without any user intervention. No data stored on an encrypted volume can be read (decrypted) without using the correct password/keyfile(s) [...]
Recently, I have been working towards establishing an enterprise framework for PGP encryption. In that regards, I came across this very useful link that outlines the basic concepts of cryptography. I am simply summarizing these concepts in short.
Encryption and Decryption
Data that can be read and understood without any special measures is called plaintext or cleartext. The [...]
