Cryptanalysis and Communications Security Miscellany

I’m in the process of registering this blog with Technorati.  In order to do so, I need to post a certain alphanumeric.  It seemed to me that just posting NVP97RC26U2G by itself would not be very interesting.

Accordingly, I thought I would post a few interesting links I’ve run across pertaining to signals intelligence and communication security, primarily from a historical perspective.  That would give this post a reason for living and, I think, would be in spirit of NVP97RC26U2G.

  • Kathryn A. Schwartz had a fascinating article in Cryptologia 33:4 (October, 2009) about Arab cryptology.  Recently discovered texts indicate that the Arabs were doing very sophisticated cryptanalytic work as early as the 9th century CE.  This included doing frequency analyses and searching for cribs.  Kathryn, whom I know slightly, tells me that she is presently working on a PhD and intends to write her dissertation on Arab use of codes and ciphers.
  • New Zealand’s Government Communications Security Board, their equivalent of NSA or GCHQ, has published an 11 page history of communications security in New Zealand up through the 1970s.  It’s worth a read.  
  • Finally, I recommend “Dirk’s Weblog” run out of Belgium.  Dirk describes his blog this way:  “On this blog you will find posts, weblinks and information about cryptography, security, Intelligence Services, Signals Intelligence, the Cold War, science and technology, software and other hopefully interesting stuff.”  The current most recent posting is about the Mythbusters television show and cryptography.  Another recent post is about Heinz Felfe, who was head of the West German counterintelligence service and was also a spy for the KGB.
