FIELD: computer equipment.
SUBSTANCE: method for remote loading of a set of cryptographic keys into a smart terminal comprises stages, at which the working module generates a request to receive a certificate; request is received by a service provider server, where a certificate is generated; certificate is sent to a working module which generates a request for loading a set of symmetric keys to a service provider server, where random private key is generated for working module and is encrypted by random public key; in the keys distribution module, the random public key is encrypted with the working module certificate; signing is carried out with private key; working module receives response from service provider server, decrypts secret key with its private key and saves it; working module requests a service provider server to provide a set of symmetric keys; service provider server generates a set of random keys and sends them to working module by encrypted secret key; working module receives a set of keys, decrypts them and, during verification, takes the received set of keys into operating mode and uses these keys to perform transactions.
EFFECT: technical result is to improve the security level of smart terminals.
