<
2016/6/13
The logical basis for information theory is the newly developed logic of partitions that is dual to the usual Boolean logic of subsets. The key concept is a "distinction" of a partition, an ordered pa...
Information-Theoretical Analysis of Two Shannon's Ciphers

2016/5/3
We describe generalized running key ciphers and
apply them for analysis of two Shannon’s methods. In particular,
we suggest some estimation of the cipher equivocation and the
probability of correct...

We revisit the classical problem: given a memoryless source
having a certain amount of Shannon Entropy, how many random bits can
be extracted? This question appears in works studying random number
