Detailed Description

The interface used by all covert channels.

CovertChannel is the abstract class all covert channels you want to use have to inherit from. It defines the interface for a covert channel. You can add CovertChannel objects to the ChannelManager to use them.

Constructor & Destructor Documentation

virtual whisper_library::CovertChannel::~CovertChannel ( )

inlinevirtual

Destructor.

Virtual destructor so that the destructor of derived classes is called

pure virtual

Returns

the ID of the covert channel

Implemented in whisper_library::TimingCovertChannel, whisper_library::PacketLengthCovertChannel, and whisper_library::TcpHeaderCovertChannel.

virtual std::string whisper_library::CovertChannel::info ( ) const

pure virtual

Returns

some information about the covert channel

Implemented in whisper_library::TimingCovertChannel, whisper_library::PacketLengthCovertChannel, and whisper_library::TcpHeaderCovertChannel.

virtual CovertChannel* whisper_library::CovertChannel::instance ( )

pure virtual

Returns

an instance of this covert channel

Implemented in whisper_library::TimingCovertChannel, whisper_library::PacketLengthCovertChannel, and whisper_library::TcpHeaderCovertChannel.

virtual std::string whisper_library::CovertChannel::name ( ) const

pure virtual

Returns

name of the covert channel

Implemented in whisper_library::TimingCovertChannel, whisper_library::PacketLengthCovertChannel, and whisper_library::TcpHeaderCovertChannel.

pure virtual

configures the covert channel

Parameters

arguments

Arguments that are given to the covert channel

Implemented in whisper_library::TimingCovertChannel, and whisper_library::TcpHeaderCovertChannel.

virtual void whisper_library::CovertChannel::setOutput ( function< void(string)>  output )

pure virtual

sets the output method

Parameters

output

the method the covert channel uses to output the received messages

Implemented in whisper_library::TimingCovertChannel, and whisper_library::TcpHeaderCovertChannel.
