Generic Connection Framework (GCF) Security Checks
Access to connections of the required protocol types via the methods of
javax.microedition.io.Connector is governed by certain
javacardx.io.ConnectorPermission checks, as described below:
| Protocol | URI Form | Permission Check |
| TCP/IP Client Socket | socket://{host}:{port} |
ConnectorPermission("socket://{host}:{port}", "connect") |
| TCP/IP Server Socket | socket://:{port} |
ConnectorPermission("socket://:{port}", "listen") |
| HTTP 1.1 | http://{host}[:{port}][{path}] |
ConnectorPermission("http://{host}[:{port}][{path}]", "connect") |
| HTTPS | https://{host}[:{port}][{path}] |
ConnectorPermission("https://{host}:{port}[{path}]", "connect") |
| Secure Client Socket | ssl://{host}:{port} |
ConnectorPermission("ssl://{host}:{port}", "connect") |
| Secure Server Socket | ssl://:{port} |
ConnectorPermission("ssl://:{port}", "listen") |
| File I/O | file://{path} (reading)file://{path} (writing) |
ConnectorPermission("file://{path}", "read")ConnectorPermission("file://{path}", "write") |
| Datagram Socket | datagram://{host}:{port}datagram://:{port} |
ConnectorPermission("datagram://{host}:{port}", "connect")ConnectorPermission("datagram://:{port}", "listen") |
javax.microedition.io.InputConnection.openDataInputStream(), javax.microedition.io.InputConnection.openInputStream(),
javax.microedition.io.OutputConnection.openDataOutputStream() and javax.microedition.io.OutputConnection.openOutputStream() result in the same permission checks
as the ones described above for the methods of javax.microedition.io.Connector.
Connector.open() and a call to InputConnection.openInputStream() (for example) on
the returned Connection object may result in a SecurityException to be thrown if the permission
is no longer granted.
The methods javax.microedition.io.StreamConnectionNotifier.acceptAndOpen() and javax.microedition.io.DatagramConnection.receive() result in permission checks, as described below:
| Protocol | URI Form of the client connection being accepted | Permission Check |
| TCP/IP Server Socket ( StreamConnectionNotifier.acceptAndOpen() method) |
socket://{host}:{port} |
ConnectorPermission("socket://{host}:{port}", "accept") |
| Secure Server Socket ( StreamConnectionNotifier.acceptAndOpen() method) |
ssl://{host}:{port} |
ConnectorPermission("ssl://{host}:{port}", "accept") |
| Datagram Socket ( DatagramConnection.receive() method) |
datagram://{host}:{port} |
ConnectorPermission("datagram://{host}:{port}", "accept") |
