Abstract
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.

(canceled)
An information processing device comprising:
- circuitry to configure to
- store a secret key generated from a given value 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 a secret key generated from a given value and a random number received from the external device that provides a service;
- transmit the public key to the external device;
- and
- conduct authentication with the external device using the secret key.
An information processing method comprising:
- storing, using circuitry, a secret key generated from a given value and a random number received from an external device that provides a service;
- generating, using a function identically set in a plurality of the services, a public key from a Multivariate Quadratic (MQ) function and a secret key generated from a given value and a random number received from the external device that provides a service;
- transmitting, using the circuitry, the public key to the external device;
- and
- conducting, using the circuitry, authentication with the external device using the secret key.
A non-transitory computer-readable storage medium including a program stored thereon, which, when executed by a computer, causes the computer to perform an information processing method, the method comprising:
- storing a secret key generated from a given value and a random number received from an external device that provides a service;
- generating, using a function identically set in a plurality of the services, a public key from a Multivariate Quadratic (MQ) function and a secret key generated from a given value and a random number received from the external device that provides a service;
- transmitting the public key to the external device;
- and
- conducting authentication with the external device using the secret key.
