All Implemented Interfaces:

Serializable, Comparable<MatcherProtectionType>, Constable

public enum MatcherProtectionType
extends Enum<MatcherProtectionType>

The MATCHER_PROTECTION constants are flags in a bit field represented as a 16 bit long integer. They describe the method an authenticator uses to protect the matcher that performs user verification. These constants are reported and queried through the UAF Discovery APIs and used to form authenticator policies in UAF protocol messages. Refer to [UAFAuthnrCommands] for more details on the matcher component. Each constant has a case-sensitive string representation (in quotes), which is used in the authoritative metadata for FIDO authenticators.

Enum Constant Details

MATCHER_PROTECTION_SOFTWARE

public static final MatcherProtectionType MATCHER_PROTECTION_SOFTWARE

This flag MUST be set if the authenticator's matcher is running in software. Exclusive in authenticator metadata with MATCHER_PROTECTION_TEE, MATCHER_PROTECTION_ON_CHIP.

NOTE: The above requirements apply to authenticators; this library DOES NOT enforce them.

• FIDO Registry of Predefined Values §3.3 Matcher Protection Types

MATCHER_PROTECTION_TEE

public static final MatcherProtectionType MATCHER_PROTECTION_TEE

This flag SHOULD be set if the authenticator's matcher is running inside the Trusted Execution Environment [TEE]. Mutually exclusive in authenticator metadata with MATCHER_PROTECTION_SOFTWARE, MATCHER_PROTECTION_ON_CHIP.

NOTE: The above requirements apply to authenticators; this library DOES NOT enforce them.

See Also:

• FIDO Registry of Predefined Values §3.3 Matcher Protection Types

MATCHER_PROTECTION_ON_CHIP

public static final MatcherProtectionType MATCHER_PROTECTION_ON_CHIP

This flag SHOULD be set if the authenticator's matcher is running on the chip. Mutually exclusive in authenticator metadata with MATCHER_PROTECTION_TEE, MATCHER_PROTECTION_SOFTWARE

NOTE: The above requirements apply to authenticators; this library DOES NOT enforce them.

Method Details

values

public static MatcherProtectionType[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static MatcherProtectionType valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null

fromValue

public static MatcherProtectionType fromValue(int value)

Returns:

If value matches any MatcherProtectionType constant, returns that constant instance. Otherwise throws IllegalArgumentException.

fromName

public static MatcherProtectionType fromName(String name)

Returns:

If name matches any MatcherProtectionType constant, returns that constant instance. Otherwise throws IllegalArgumentException.

getValue

public short getValue()

getName

public String getName()
