, each of them is considered to be a separate measurement. From these positions process of virtual key 
creation can be represented as initial key in some M-dimensional space simultaneously on all to his(its) measurements virtualization with the subsequent unification of virtualization results into some function of this space which will represent a virtual key:
(1)
(2)
Where UNIF(.) - unification procedure;
(.) - virtualization procedure defining j-measurement;
- initial key formed on the basis of given key data 
;
- projection of virtual key onto j-measurement;
The unfolded key is formed by obtained virtual key devirtualization:
(3)
Expressions (1) - (3) define common algorithm of unfolded key creation at multivariate performance of key bands virtual sample spaces. The concrete definition of the given algorithm is carried out by unification procedure definition . Variants of such concrete definition are represented by expressions (4) and (5)
(4)
(5)
Software implementation of the algorithms given in expressions (4), (5) allowed software encryption complex creation, which opens a possibility of absolute undeciphering capability support. Experimental researches of the complex confirm its significant potential possibilities. Given results are obtained during researches at Russian Federation Education Ministry grant T02-03.1-816 support.
