## Abstract

An information processing apparatus includes a storage unit and a processor. The storage unit stores a private key corresponding to a public key stored in a storage apparatus connected to the information processing apparatus through a network. The processor receives first data from the network. The processor decrypts second data included in the first data using the private key. The processor determines whether a result of the decryption is third data. The processor activates the information processing apparatus when the result of the decryption is the third data.

## Claims

### Claim 1

An information processing apparatus comprising:
a storage unit to store a private key corresponding to a public key stored in a storage apparatus connected to the information processing apparatus through a network; and
a processor to
receive first data from the network,
decrypt second data included in the first data using the private key,
determine whether a result of the decryption is third data, and
activate the information processing apparatus when the result of the decryption is the third data.

### Claim 2 (depends on 1)

The information processing apparatus according to claim 1, wherein
the third data is included in the first data.

### Claim 3

A method for activating a computer, the method comprising:
receiving first data from a network;
decrypting, by a processor included in the computer, second data included in the first data using a private key corresponding to a public key stored in a storage apparatus connected to the computer through the network;
determining whether a result of the decryption is third data; and
activating the computer when the result of the decryption is the third data.

### Claim 4 (depends on 3)

The method according to claim 3, wherein
the third data is included in the first data.

### Claim 5

A computer-readable recording medium storing a program that causes a processor included in a computer to execute a procedure, the procedure comprising:
receiving first data from a network;
decrypting second data included in the first data using a private key corresponding to a public key stored in a storage apparatus connected to the computer through the network;
determining whether a result of the decryption is third data; and
activating the computer when the result of the decryption is the third data.

### Claim 6 (depends on 5)

The computer-readable recording medium according to claim 5, wherein
the third data is included in the first data.
