FIELD: information technology. ^ SUBSTANCE: invention refers to methods and systems of data protection from unauthorised actions, changing of the content during data transfer and storage and can be used for quick generating of random numbers required for ciphering, creation of digital signature, authentication protocols etc. It is assumed to use the random number generator containing source of low intensity elementary particles, receiver containing particle detector and an events storage unit that allows obtaining instant analogue value of quantum events intensity proportional to the number of registered particles; analog-to-digital coder and a scheme equalising statistical properties of the obtained data stream and also generator setting measuring frequency and connected with the analog-to-digital coder. Thereby the simultaneous quantum process is used as a source of low-intensity elementary particles. ^ EFFECT: increase of random numbers generation speed while saving their properties comparing with other known methods and devices. ^ 1 dwg |
