Abstract

Security is simply and safely secured when communication is performed by an information processing device including: a communication unit configured to wirelessly communicate with another terminal; an identification information acquisition unit configured to acquire first identification information that is acquired through the communication unit and encrypted for specifying the other terminal, and that is decrypted with a first decryption key managed in a network service; and a key acquisition unit configured to acquire a first encryption key associated with the first identification information in the network service when second identification information for specifying an own terminal is associated with the first identification information in the network service. The communication unit transmits information encrypted with the acquired first encryption key to the other terminal.

Claims

1. An information processing device comprising:

a communication unit configured to wirelessly communicate with another terminal;

an identification information acquisition unit configured to acquire first identification information that is acquired through the communication unit and encrypted for specifying the other terminal, and that is decrypted with a first decryption key managed in a network service; and

a key acquisition unit configured to acquire a first encryption key associated with the first identification information in the network service when second identification information for specifying an own terminal is associated with the first identification information in the network service,

wherein the communication unit transmits information encrypted with the acquired first encryption key to the other terminal.

2. The information processing device according to claim 1,

wherein the communication unit transmits information encrypted with the acquired first encryption key for mutual authentication between the own terminal and the other terminal to the other terminal.

3. The information processing device according to claim 2,

wherein the information for mutual authentication includes a second encryption key associated with the second identification information.

4. The information processing device according to claim 2,

wherein the information for mutual authentication includes information for the own terminal and the other terminal to perform mutual authentication using each other'"'"'s encryption keys and decryption keys.

5. The information processing device according to claim 1,

wherein the identification information acquisition unit acquires the first identification information decrypted in the network service.

6. The information processing device according to claim 1,

wherein the first identification information includes a first user ID indicating a user of the other terminal.

7. The information processing device according to claim 6,

wherein the second identification information includes a second user ID indicating a user of the own terminal, and

wherein the key acquisition unit acquires the first encryption key when the first user ID and the second user ID are associated in the network service.

8. The information processing device according to claim 1,

wherein the first identification information includes a first device ID for uniquely specifying the other terminal.

9. The information processing device according to claim 8,

wherein the second identification information includes a second device ID for uniquely specifying the own terminal, and

wherein the key acquisition unit acquires the first encryption key when the first device ID and the second device ID are associated in the network service.

10. The information processing device according to claim 1, comprising:

a key generation unit configured to generate a second encryption key and a second decryption key for decrypting information encrypted with the second encryption key; and

a storage unit configured to store the acquired first identification information in association with the acquired first encryption key,

wherein the identification information acquisition unit decrypts the first identification information with the second decryption key when the first identification information encrypted with the second encryption key is acquired, and

wherein the communication unit extracts the first encryption key associated with the acquired first identification information and transmits information encrypted with the extracted first encryption key to the other terminal.

11. A wireless communication system comprising:

a first information processing device; and

a second information processing device configured to wirelessly communicate with the first information processing device,

wherein the first information processing device includes

a first communication unit configured to transmit encrypted first identification information for specifying the first information processing device to the second information processing device, and

wherein the second information processing device includes

an identification information acquisition unit configured to acquire the encrypted first identification information, decrypt the acquired first identification information with a first decryption key managed in a network service, and acquire the decrypted first identification information,

a key acquisition unit configured to acquire a first encryption key associated with the first identification information in the network service when second identification information for specifying the second information processing device is associated with the first identification information in the network service, and

a second communication unit configured to transmit information encrypted with the acquired first encryption key to the first information processing device.

12. An information processing method comprising:

acquiring first identification information that is acquired through a communication unit configured to wirelessly communicate with another terminal and encrypted for specifying the other terminal, and that is decrypted with a first decryption key managed in a network service;

acquiring a first encryption key associated with the first identification information in the network service when second identification information for specifying an own terminal is associated with the first identification information in the network service; and

transmitting information encrypted with the acquired first encryption key to the other terminal.

13. A program causing a computer to execute:

acquiring first identification information that is acquired through a communication unit configured to wirelessly communicate with another terminal and encrypted for specifying the other terminal, and that is decrypted with a first decryption key managed in a network service;

acquiring a first encryption key associated with the first identification information in the network service when second identification information for specifying an own terminal is associated with the first identification information in the network service; and

transmitting information encrypted with the acquired first encryption key to the other terminal.
