■ Authentication Information Sharing Function

● Sharing the authentication information
Authentication information at login and authentication information for MEAP application were
managed separately, so it was very inconvenient because authentication was executed many
times.
In the MEAP environment, the unified authentication function which authentication information
can be shared even between MEAP applications was added.
Supported MEAP Specifications is Ver.59 and both device and MEAP application need to
support this version in order to use this function.
There are 2 types for authentication information sharing: Volatile Credential which the
registered information is discarded at logout or shutdown of the device, and Persistent
Credential which the registered information is not discarded even at logout.
● Volatile Credential
Volatile Credential is used when sharing the authentication information between applications
which log in (authenticate) to the same security domain.
F-2-212 Credential is registered using a login application, so the application which accesses to the
security domain used for authentication by login application can use the Credential.
● Persistent Credential
Persistent Credential is used to help entry of authentication information when logging in
(authenticating) to a different security domain.
Credential is registered using a general MEAP application, so the authentication information
can be reused when the same user logs in for the second time or later.
