NSA surveillance: how to stay secure. Now that we have enough details about how the NSA eavesdrops on the internet, including today's disclosures of the NSA's deliberate weakening of cryptographic systems, we can finally start to figure out how to protect ourselves.

NSA surveillance: how to stay secure

For the past two weeks, I have been working with the Guardian on NSA stories, and have read hundreds of top-secret NSA documents provided by whistleblower Edward Snowden. I wasn't part of today's story – it was in process well before I showed up – but everything I read confirms what the Guardian is reporting. At this point, I feel I can provide some advice for keeping secure against such an adversary. The primary way the NSA eavesdrops on internet communications is in the network. That's where their capabilities best scale.

Leveraging its secret agreements with telecommunications companies – all the US and UK ones, and many other "partners" around the world – the NSA gets access to the communications trunks that move internet traffic. 1) Hide in the network. Crypton. An Overview of Cryptography. 1.

An Overview of Cryptography

INTRODUCTION Does increased security provide comfort to paranoid people? Or does security provide some very basic protections that we are naive to believe that we don't need? During this time when the Internet provides essential communication between tens of millions of people and is being increasingly used as a tool for commerce, security becomes a tremendously important issue to deal with. There are many aspects to security and many applications, ranging from secure commerce and payments to private communications and protecting passwords. One essential aspect for secure communications is that of cryptography, which is the focus of this chapter.

Email Security using Public Key Cryptography

There are several open source software tools like GnuPG and WinPt to accomplish these tasks. The primary benefit of public key cryptography is that it allows people who have no preexisting security arrangement to exchange messages securely. The need for sender and receiver to share secret keys via some secure channel is eliminated; all communications involve only public keys, and no private key is ever transmitted or shared. This Tip describes the installation and use of GnuPG and WinPt If you want to send an encrypted mail to somebody, you encrypt it using the public key. GnuPG ( GnuPG is a complete and free replacement for PGP. WinPt WinPT (Windoze Privacy Tray) is a taskbar utility for doing data en- or decryption.
