Saluting the enigma ....

Let us all remember and salute Alan Turing -- the giant who contributed so much to computer science and cryptography. So great were his contributions to these sciences, that the world of computer science remembers him gratefully today :

To have a glimpse of this giant visit the web pages:

And, remember Claude Shannon another giant who walked this world with us. Shannon's legacy.

Study material

Are you seriously serious about security ? Take this simple test !
Avoid blackbox software if you are seriously serious about e-security.
Home alone ? Is your home computer safe ? What should you do, to ensure security in your home computer ?
Want to avoid security related misadventures ? See this rogues gallery of security blunders and Confession #1 and Confession #2 ... and draw your own conclusions ! In spite of all the wishful dreams and promises, here is what you get from this same vendor. How long more do you want to put up with this scandal ?
Not to worry, here is : Linux -- The ray of hope. Change your religion. It is still not too late !
How not to keep a secret ! It is important for you to create and then publicise your PGP public key. Here is one nice example of how to let the world know about your PGP public key.
Only a lucky few can learn from the guru. Attend this one day seminar on PGP and crypto. You can also choose from a whole lot of training services fromAlgologic .

Practice what you preach !

Make sure that the contents of this CDROM have not been tampered with ! Make sure that it is a dependable and authentic copy ! Here's how you can do that !

Learning resources and links

Cryptography deals with the science of keeping secrets. It is amazing to note the amount of information available for free from the web about cryptography, e-security and related matters. You just have to scan this sample collection, to realise how much information is available to you.

Elliptic curve cryptography

Elliptic curve cryptography (ECC) offers a powerful alternative to the RSA cryptographic technique. Start with a short and quick introduction to ECC. See some of your questions on ECC answered in this FAQ (slightly old, but still useful). And then take a longer introduction to ECC. And, then look out for further references.

Passwords

Password authentication over a hostile network has always been a challenging task. Learn about some of the issues involved. This page gives more pointers to the subject of password authentication.
 
EKE -- encrypted key exchange is a promising technique for resolving some of the hurdles in password authentication. Take a peek at SPEKE (an EKE tool), and read more details about SPEKE.

The RSA algorithm

The RSA trio !
  • Meet the R of the RSA algorithm.
     
  • Meet the S of the RSA algorithm.
     
  • Meet the A of the RSA algorithm.
