Description: Different methods of data en/decryption.
 

Destructive Legacies of the One Time Pad. 
  The benefit of the OTP is that it guarantees unbreakable crytpo strength when the ciphertext has been generated using a random key that is equal in length to the message length but that only caters for one form of attack in a modern number- theoretic computer driven cipher i.e. a statistical attack on the ciphertext.... more »

A Modernised One –Time Pad is Quite Feasible. 
  A modernised OTP that does not have the historic key transport problem, has a manageable message/key length, has ciphertext that is demonstrably random, does not show footprints in the ciphertext even if the key is used more than once (which it isn’t but could be made to do so – has been checked), has an acceptable message length, is... more »

Towards a secure, vector-oriented cryptosystem 
  I got to wondering how hard it would be to write a possibly-actually-secure vector-based cryptosystem at a similar level of sophistication as adacrypt's efforts. It turns out the answer is "not very". I present, for your consideration, the kid-sister cryptosystem "vector-otp". README: <[link]>... more »

The One-Way Function. 
  Two points in space can be defined by the position vector that connects the two points. In everyday standard usage one of the points is taken to be fixed at (0,0,0) and every other point in the whole of space can be expressed as being relative to this point. But users are not bound to always uses (0,0,0) as the standard... more »

Making the Ciphertext String Itself Truly Random – The Conjecture. 
  I have made the point recently that the ciphertext string is never random and indeed the clever cryptanalyst who knows this will try and determine to what extent that is instantaneously true so that he may mount a statistical mapping attack using that as the basis (an advanced Kasiski/Babbage attack).... more »

Why do block ciphers still have a "decrypt" operation? 
  These are merely theoretical considerations, but I've been seriously wondering about this. It seems to me that most modes of operation of block ciphers like CFB, OFB, counter mode, etc. don't use the decryption operation of the cipher at all. Thus if anyone were to design a cipher that had blazing fast... more »

The Real & Final Enigma. 
  Okay, I have being labouring several points rather heavily, excessively perhaps, in recent days but I cannot allow my very hard work over many years to be trivialised by foul-mouthed ridiculous claims. This hopefully, will be the last piece of defensive posting necessary to debunk the attempts at wrecking my work.... more »

Random Numbers from Text Files 
  I wrote an article on my website at futurebeacon.com at this page: [link] It outlines a method of extracting randomness from ordinary files. Any comments would be appreciated. Jim Adrian j...@futurebeacon.com
