FIELD: computer engineering; cryptographic systems.
SUBSTANCE: method is based on entropy valuation calculation and writing of mixed packed data into corresponding cells in different memory block areas. On the basis of written data new initial value is formed. Device for initial value of pseudorandom value generator forming contains data source analysis and current entropy valuation calculation means, data package means, data mix means, data accumulation and entropy valuation forming means, new initial value forming means.
EFFECT: method and device provide the capability of initial values forming, which provide dynamic source speed valuation, classification of sources by fast and slow, reliable and unreliable, and also forming of initial values taking into account speed characteristics of sources and reliability of these sources.
