FIELD: cryptographic systems engineering.
SUBSTANCE: device for reproduction of secret key of cryptographic system contains: processor, volume of energy-independent memory, operatively connected to aforementioned processor, and a set of parameters for secret key, stored in aforementioned volume of energy independent memory with utilization of lesser memory volume, than for full set of parameters, using Chinese theorem about remainder {p,q,dp,dq,v}, and providing greater efficiency of computations, then minimal set of parameters {p,q}, while secret key may be reproduced from aforementioned stored set of parameters of secret key.
EFFECT: creation of method and device for storage and reproduction of secret key in cryptographic system by means of parameterization of secret key using lesser amount of memory, and increased efficiency of computations is reached.
