Abstract

An information processing apparatus that executes authentication processing using authentication information received from a terminal includes a first authentication unit configured to execute first authentication processing using second authentication information and preliminarily managed authentication information, the second authentication information being obtained by encrypting first authentication information received from the terminal, and a second authentication unit configured to execute second authentication processing different from the first authentication processing, wherein, in a case where the second authentication information is authenticated by the first authentication unit, the first authentication information is managed to be usable by the second authentication unit.

Claims (29)

1. An information processing apparatus that executes authentication processing using authentication information received from a terminal, the information processing apparatus comprising:

at least one memory storing instructions; and

one or more processors configured by the instructions to perform operations comprising:

executing first authentication processing using second authentication information and preliminarily managed authentication information, the second authentication information being obtained by encrypting first authentication information received from the terminal;

executing second authentication processing different from the first authentication processing; and

enabling a Federal Information Processing Standards (FIPS) mode,

wherein, in a case where the second authentication information is authenticated in the first authentication processing, the first authentication information is managed to be usable in the second authentication processing, and

wherein, in a case where the FIPS mode is enabled, after executing the first authentication processing using the second authentication information, the one or more processors execute the second authentication processing using the authentication information received from the terminal.

2. The information processing apparatus according to claim 1 , wherein the FIPS mode is a mode for prohibiting use of a specific encryption scheme.

3. The information processing apparatus according to claim 2 ,

wherein the specific encryption scheme includes a Message Digest algorithm (MD) 5 hash scheme, and

wherein the MD5 hash scheme is an encryption scheme used to acquire the second authentication information from the first authentication information.

4. The information processing apparatus according to claim 1 , wherein, in a case where the FIPS mode is not enabled, the information processing apparatus uses the first authentication processing to authenticate the authentication information received from the terminal even after the second authentication information is authenticated in the first authentication processing.

5. The information processing apparatus according to claim 1 , wherein, in a case where the FIPS mode is not enabled, the information processing apparatus uses the first authentication processing to authenticate the authentication information received from the terminal without managing the first authentication information even after the second authentication information is authenticated in the first authentication processing.

6. The information processing apparatus according to claim 1 ,

wherein the information processing apparatus is an image forming apparatus having at least a print function, and

wherein, in a case where the first authentication information is authenticated in the first authentication processing or the second authentication processing, the image forming apparatus provides at least one function that the image forming apparatus has to the terminal having transmitted the first authentication information.

7. A control method for an information processing apparatus that executes authentication processing using authentication information received from a terminal, the control method comprising:

executing first authentication processing using second authentication information and preliminarily managed authentication information, the second authentication information being obtained by encrypting first authentication information received from the terminal;

executing second authentication processing different from the first authentication processing; and

enabling a Federal Information Processing Standards (FIPS) mode,

wherein, in a case where the second authentication information is authenticated in the first authentication processing, the first authentication information is managed to be usable in the second authentication processing, and

wherein, in a case where the FIPS mode is enabled, after executing the first authentication processing using the second authentication information, the second authentication processing is executed using the authentication information received from the terminal.

8. A non-transitory computer-readable storage medium storing a program including instructions, which when executed by one or more processors of an information processing apparatus that executes authentication processing using authentication information received from a terminal, cause the information processing apparatus to:

execute first authentication processing using second authentication information and preliminarily managed authentication information, the second authentication information being obtained by encrypting first authentication information received from the terminal;

execute second authentication processing different from the first authentication processing; and

enable a Federal Information Processing Standards (FIPS) mode,

wherein, in a case where the second authentication information is authenticated in the first authentication processing, the first authentication information is managed to be usable in the second authentication processing, and

wherein, in a case where the FIPS mode is enabled, after executing the first authentication processing using the second authentication information, the second authentication processing is executed using the authentication information received from the terminal.
