title: Blogs and Books on Encryption and Security
body: <p>Could any of you experienced programmers / ethical hackers out there recommend some blogs or books on security/encryption? The only blogs I look at now are,</p>
  
  <ul>
  <li><p><a href="http://blogs.msdn.com/shawnfa/archive/2009/03/17/authenticated-symmetric-encryption-in-net.aspx" rel="nofollow noreferrer">.Net Security Blog</a>.</p></li>
  <li><p><a href="http://blog.absolute.com/cybercrimes-more-sophisticated-but-so-too-are-countermeasures/" rel="nofollow noreferrer">Laptop Security Blog</a>.</p></li>
  <li><p><a href="http://www.schneier.com/index.html" rel="nofollow noreferrer">Schneier On Security</a>.</p></li>
  </ul>
  
  <p>I am especially interested in the mathematical theory behind the security/encryption, not just how to use it.</p>
