Make first deb-src package by example cri-o

Anonymity and Untraceability

The following text consists of two logically connected parts. The first part constructively rules out the assumption that untraceability supposes anonymity. The second part enumerates specific practical tasks in the form of various scenarios when digital signatures (DS) do not provide correct solutions to the task. It is demonstrated that a complete solution can be obtained through a special combination of DS and an interactive anonymous identification protocol. Read more Read more
