Information processing device, information processing method, and program

摘要

There is provided an information processing device including a secret key generator that generates a secret key from a random number received from an external device that provides a service, and a given value, a public key generator that generates a public key on the basis of the secret key by using a function identically set in a plurality of the services, a transmitter that transmits the public key to the external device, and an authentication processor that conducts authentication with the external device using the secret key.

1. An information processing device, comprising:
circuitry configured to:
store a secret key that is generated from a hash value computed between a master secret key and a random number received from an external device that provides a service;generate, by using a function identically set in a plurality of the services, a public key from a Multivariate Quadratic (MQ) function and the secret key generated from the hash value and the random number;transmit the public key to the external device; andconduct authentication with the external device using the secret key,wherein the circuitry is configured to receive the random number based on transmission of identity data from the information processing device to the external device.
