Method Detail

getDefaultConfiguration

public org.ssonet.mechanisms.MechanismConfiguration getDefaultConfiguration()

Specified by:

getDefaultConfiguration in interface Mechanism

Overrides:

getDefaultConfiguration in class AbstractAccountabilityMechanism

Returns:

default configuration of RSA

init

public void init(org.ssonet.io.IOStream ioStream,
                 int securityGoal,
                 org.ssonet.mechanisms.MechanismConfiguration ownMechanismConfiguration)

Initialize without key exchange

Specified by:

init in interface Mechanism

Overrides:

init in class AbstractAccountabilityMechanism

Parameters:

ioStream - mechanism IOStream

ownMechanismConfiguration - own mechanism configuration, for this method the mechanism configuration must also enclose the respective key (private or public) for the intended operation (sign or test)

securityGoal - the security goal, for which the algorithm is used

init

public void init(org.ssonet.io.IOStream ioStream,
                 int securityGoal,
                 org.ssonet.mechanisms.MechanismConfiguration ownMechanismConfiguration,
                 org.ssonet.mechanisms.MechanismConfiguration partnerMechanismConfiguration,
                 org.ssonet.net.KeyExchange keyExchange)
          throws ParameterNotCompatibleException

Initialize with key exchange Must be synchronized, so that not two keypairs are created an written to the context. with synchronization, the first call creates the keypair, and the second call finds the allready created keys.

Specified by:

init in interface Mechanism

Overrides:

init in class AbstractAccountabilityMechanism

Parameters:

ioStream - mechanism IOStream

ownMechanismConfiguration - own mechanism configuration

partnerMechanismConfiguration - partner mechanism configuration

keyExchange - prepared key exchange protocol

securityGoal - the security goal, for which the algorithm is used

Throws:

ParameterNotCompatibleException - if negotiation of parameters fails
