Information processing apparatus, software installing method, and recording medium

1. A recording medium comprising an IC chip, the IC chip being mounted on the recording medium and including circuitry configured to:

record information;

transmit and receive information to and from an external apparatus without contacting the external apparatus; and

communicate with the external apparatus and execute mutual authentication between the IC chip and the external apparatus for permitting access to the recorded information, wherein

data of one or more kinds of software is recorded using said circuitry,

at least identification information for respective kinds of software recorded on a recording surface of the recording medium, key information necessary for installation of the respective kinds of software, and usage control information indicating a number of installations available for installation of the respective kinds of software are recorded using said circuitry of the IC chip, said identification information and said usage information being displayed on a display screen to a user prior to said mutual authentication between the IC chip and the external apparatus,

the key information is readout to the external apparatus only when said mutual authentication is correctly performed between the IC chip and the external apparatus, and

rewriting of the usage control information, stored using said circuitry of the IC chip, by the external apparatus is allowed only when said mutual authentication is correctly performed between the IC chip and the external apparatus.

2. The recording medium according to claim 1 , wherein

information recorded on the recording surface is rewritable, and

rewriting of the identification information, the key information, and the usage control information by the external apparatus is allowed only when mutual authentication is correctly performed between the IC chip and the external apparatus.

3. The recording medium according to claim 1 , wherein

the data of the respective kinds of software is recorded on the recording surface as compressed data, and

the key information is information for starting decompression processing for the compressed data corresponding to the key information.

4. The recording medium according to claim 1 , wherein

the data of the respective kinds of software is recorded on the recording surface as encrypted data, and

the key information is a decryption key for decrypting the encrypted data corresponding to the key information.

5. The recording medium according to claim 1 , wherein installation environment information indicating an environment of a device or software capable of installing the respective kinds of software recorded on the recording surface is further recorded using said circuitry.

6. A recording medium comprising an IC chip, the IC chip being mounted on the recording medium and including circuitry configured to:

record information;

transmit and receive information to and from an external apparatus without contacting the external apparatus; and

communicate with the external apparatus and execute mutual authentication between the IC chip and the external apparatus for permitting access to the recorded information, wherein

data of one or more kinds of software and encrypted key information obtained by encrypting key information necessary for installation of respective kinds of software are recorded using said circuitry,

at least identification information for the respective kinds of software recorded on a recording surface of the recording medium, a recording media key including information peculiar to the recording medium for decrypting the encrypted key information recorded on the recording surface of the recording medium, and usage control information indicating a number of installations available for installation of the respective kinds of software are recorded using said circuitry of the IC chip, said identification information and said usage information being displayed on a display screen to a user prior to said mutual authentication between the IC chip and the external apparatus,

the recording media key is readout to the external apparatus only when said mutual authentication is correctly performed between the IC chip and the external apparatus, and

rewriting of the usage control information, stored using said circuitry of the IC chip, by the external apparatus is allowed only when said mutual authentication is correctly performed between the IC chip and the external apparatus.

7. The recording medium according to claim 1 , wherein the IC chip is connected to an antenna mounted on the recording medium and is configured to receive a radio wave or a magnetic field from the external apparatus through the antenna.

8. The recording medium according to claim 1 , wherein said mutual authentication includes generating random numbers, exchanging encrypted random numbers between the IC chip and the external apparatus, and determining whether a decrypted version of the encrypted random numbers correspond to the random numbers.

9. The recording medium according to claim 1 , wherein said mutual authentication includes a first authentication performed at the IC chip prior to a second authentication performed at the external apparatus.
