View source for Security and Trust Services API for J2ME

The '''Security and Trust Services API for J2ME (SATSA)''' is a collection of Java ME-based [[Application programming interface|API]]s that provides compliant devices with additional [[Cryptography|cryptographic]] security features. It permits the communication of a Java ME application with a smartcard through the [[Smart card application protocol data unit|APDU]] and [[Java Card]] RMI protocols. SATSA was developed under the [[Java Community Process]] as [http://www.jcp.org/en/jsr/detail?id=177 JSR 177].

It covers the following features, not natively supported by the original Java ME platform:

* Secure storage and exchange of data with third parties (such as the data exchanged during payment transactions).
* User identification and authentication during the exchange of data with third parties.

==Implementation of SATSA==
The SATSA API is considered an optional feature by [[Company:Sun Microsystems|Sun Microsystems]], and is not mandated in all Java ME phones. However, device manufacturers may include it, if required. Several device manufacturers have already chosen to include SATSA in some products. Among them are several mobile phone manufacturers:

* [[Company:Motorola|Motorola]]
* [[Company:Nokia|Nokia]] (from [[Software:Series 40|Series 40]] onwards, on a selective basis)
* [[Company:Samsung|Samsung]]
* Sony Ericsson (from [[Sony Ericsson Java Platform|JP-8]] onwards)
