| Let me rephrase my sequence. Create a sequence of 256 consecutive | bytes, with the first byte having the value of 0, the second byte the | value of 1, ... and the last byte the value of 255. If you measure | the entropy (according to Shannon) of that sequence of 256 bytes, you | have maximum entropy. Shannon entropy is a property of a *source*, not a particular sequence of values. The entropy is derived from a sum of equivocations about successive outputs.

If we read your "create a sequence...", then you've described a source - a source with exactly one possible output. All the probabilities will be 1 for the actual value, 0 for all other values; the equivocations are all 0. So the resulting Shannon entropy is precisely 0. -- Jerry --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to [EMAIL PROTECTED]
