An update on my XOR-Sum Uniqueness Cryptanalysis attack

I have updated the information I wrote about what I consider to be a potentially new type of cryptanalysis attack.

Although the described attack is relevant to my BUGS algorithm, it could also be used to attack any algorithms using some type of Cipher Block Chaining  (CBC) or Cipher Feedback (CFB) mode of operation, in fact, any algorithms using a XOR function between plaintext blocks as part of their encryption process.

The explanation assume the reader is familiar with the different block cipher modes of operation. Although I start with a simple example, it helps setting the context for which the final attack could be in theory applied to: any XOR operations.
