Abstract
An access control method controls access from an information processing apparatus which is connectable to a device requiring a first password authentication to a storage medium which requires a second password authentication. The access control method automatically generates a password based on key information read from the device, when an authentication result of a password input to the information processing apparatus and a first password read from the device is correct, and enables access to the storage medium when an authentication result of the generated password and a second password read from the storage medium is correct.
Claims10
An access control method for controlling access from an information processing apparatus which is connectable to a device requiring a first password authentication to a storage medium which requires a second password authentication, comprising:
- a password generating step which automatically generates a password based on key information read from the device, when an authentication result of a password input to the information processing apparatus and a first password read from the device is correct;
- and
- an access control step which enables access to the storage medium when an authentication result of the generated password and a second password read from the storage medium is correct.
A storage apparatus loadable with a storage medium which is accessible from an information processing apparatus which is connectable to a device requiring a first password authentication, said storage medium requiring a second password authentication, said storage apparatus comprising:
- a receiving section which receives from the information processing apparatus a password which is generated when an authentication result of a password input to the information processing apparatus and the first password read from the device is correct, and is enciphered using an enciphering key which is generated based on key information from the device and read from the device;
- and
- an access control section which enables access from the information processing apparatus to the storage medium when an authentication result of the enciphered password which is deciphered based on an enciphering key read from the storage medium and the second password read from the storage medium is correct.
An information processing apparatus which is connectable to a device requiring a first password authentication and accesses a storage medium requiring a second password authentication, comprising:
- a password generating section which automatically generates a password based on key information read from the device, when an authentication result of an input password and a first password read from the device is correct;
- and
- an access control section which enables access to the storage medium when an authentication result of the generated password and a second password read from the storage medium is correct.
