One of the important components of the security of the client-bank system is the protection mechanisms based on the use of cryptographic keys. The stability of cryptographic keys is a guarantee of system reliability and, in turn, is based on the mechanisms of generating pseudo-random numbers using primary entropy sources, for the effective use of which it is necessary to define and describethe functions of the algorithm for data processing.
\nThe paper describes the basic principles of using sensors of mobile devices as primary entropy sources for cryptographic keys generators of the client-bank system in the provision of mobile banking services, defines the procedure for accumulation and processing of entropy pool from sensors, described the main functions of the procedure and detailed functional model the process of generating cryptographic keys. The obtained results make it possible to perform a detailed algorithm of the client-bank system with the use of high-entropy cryptographic keys generators in mobile banking and other services.
\nThe obtained results are focused on the implementation of algorithms and means of generating pseudo-random numbers of high entropy and can be used to reduce the risks of unauthorized access to customer information in the client-bank system through the disclosure of cryptokeys in mobile banking services. Mobile phone sensors or other devices and phenomena that are characterized by the ability to form a pool of values \u200b\u200bwith a high level of entropy can be used as sources of entropy.
