Eclipse Keyple® is an open source middleware to facilitate the implementation of terminal processing operating smart card readers, and to defined advanced secure ticketing transaction.
Keyple implements the high-level ticketing terminal APIs hosted in Eclipse Keypop®: 'Reader API', 'Card API', 'Calypso Card API', 'Calypso Crypto Symmetric API', and 'Calypso Legacy SAM API'.
The Keyple Core Libraries provides a universal service to manage smart card readers:
- The solution is able to handle any smart card reader solutions: standard (contacts/contactless PC/SC, NFC, OMAPI) or proprietary in a generic way.
- It’s also compatible with any terminal architecture: local or remote, for any kind of terminals: mobile, embedded or server. Remote smart card readers could be managed as local readers in a transparent way.
The Keyple Core can be extended with command sets of specific smart card solutions in order to define advanced secure transactions. The project hosts a first extension to support the Calypso ticketing solution.
The Keyple Calypso Libraries provides a high-level interface to implement fast and secure contactless ticketing transactions based on the Calypso standard.
- The settings of the Calypso cards & SAM APDU commands are automatically generated according to the functional operations defined by the developers.
- Cards & SAM commands are transmitted in an optimized grouping to limit network exchanges in case of distributed architecture.
Two implementations are currentely proposed for Java (dependency Java SE 8 and later, Android 7.0 or later) and for C++ (dependency C++ 11). Both implementations are based on the same oriented-object model.
The Keyple Java implementation includes 18 components:
- Core's components to manage smart card reader solutions and select secure element: 'Service Lib', 'Plugin API', 'Common API', 'Util Lib', and 'Service Resource Lib',
- Distributed System's components to operate remote readers as localy: 'Distributed Remote API', 'Distributed Remote Lib', 'Distributed Local API', 'Distributed Local Lib', and 'Distributed Network Lib',
- Card Extensions components:
- 'Calypso Card Lib' to operate secure transaction with Calypso card,
- 'Calypso Legacy SAM Lib' to manage Calypso legacy SAM,
- 'Generic Card Lib' to exchange APDU commands with any kind of smart card solution.
- Reader Plugin Extensions' components:
- 'Android NFC Plugin Lib': the library to interface the native NFC contactless readers on Android device,
- 'Android OMAPI Plugin Lib': the library to interface the OMAPI contacts readers on Android device,
- 'PC/SC Plugin Lib': the library to interface PC/SC readers to the Keyple Core,
- 'Card Resource Plugin Lib'
- 'Stub Plugin Lib': a tool to emulate readers and cards to operate Keyple without hardware elements.
The Keyple C++ implementation includes currentely 9 components similar to those in Keyple Java, but the distriubed system feature isn't yet supported, and only PC/SC & stub plugins are provided.
After Keyple 2.0, the complete list of component releases is published on this page https://keyple.org/community/changelog/.
