■ Integrated Authentication Function

● Sharing the Authentication Information
Separately managing the authentication information at login and the authentication
information for MEAP applications creates inconveniences such as that the authentication
process is executed many times.
In order to solve this problem, the device has an integrated authentication function. This
function allows authentication information to be shared between MEAP applications in a
MEAP environment.
The supported version of MEAP Specifications is Ver.59, which needs to be supported by
both the device and the MEAP application in order to use this function.
There are 2 types of authentication information that can be shared: Volatile Credential whose
registered information is discarded at the time of logout or shutdown of the device and
Persistent Credential whose registered information is not discarded at the time of logout.
● Volatile Credential
Volatile Credential is used in cases where the authentication information is shared between
applications which use the same security domain for authentication.
The credential is registered mainly by the login application, therefore the applications which
access the security domain that was used for authentication by the login application can use
the credential.
● Persistent Credential
Persistent Credential is used to help entry of authentication information when accessing a
different security domain for authentication.
The credential is registered mainly by general MEAP applications, and the authentication
information can be reused when the same user logs in for the second time or later.
