An external device allows the owner of a key to remove the key from the host system, and maintain physical possession of the device that carries the key. However, all of the options introduced are vulnerable to situations in which the host system the device is connected to has been compromised and is running malicious code. Such malicious code could, for instance, make the user believe that she is providing her key to authorize an intended transaction, but actually causes the key to be used to authorize a modified or entirely different transaction. An important advantage arises from devices where the cryptographic operation (e.g., digital signature) is actually executed on the device, and where the private key material never leaves the device (e.g., smart cards or HSMs). If the device is connected to a compromised host, the attacker s malicious code may be able to use the device to perform cryptographic operations with the user s key while it is connected. However, unlike in the case of a key disk, the malicious code cannot extract the key and continue using it after the device has been disconnected again.

Figure 7-7. Choose System.Exception from the mscorlib namespace. A Throw activity is an activity that throws an exception. You must define the exception the activity will throw, but you don t need to define a Fault Handler for that exception if you don t want to. Using this activity is the same as using the Throw part of a Try . . . Catch . . . Throw code block. This can be useful if you re checking for a specific item. If that item isn t there, you ll want to throw an exception. In this case, the activity also shows how the Fault Handler activity is executed. Leave the name of the Throw activity as the default name, and for the FaultType choose DriveNotFound from mscorlib.System.IO. This is just a random exception to see how the Fault Handler works. Execute the workflow. You ll receive a build failed message. The message states that the WorkflowTerminatedException must be added before the Handler for Exception. The reason for this is the Exception type is the default or catch-all type. When a FaultHandlersActivity is triggered, each Fault Handler is evaluated from left to right. The first Fault Handler activity that matches the exception is the one that s executed. Therefore, if you use the Exception type, which is the catch-all, it must be the last in the list of Fault Handler activities. To fix this problem, view the Faults of the workflow again, and move the WorkflowTerminatedFault activity to the leftmost area within the FaultHandlersActivity, as shown in Figure 7-8.

Once keys have been generated and stored safely, they can be used to initiate a conversation (e.g., between Alice and Bob). In the case that Alice and Bob already have access to the same

The ContextMenu control is similar to the Menu control except that a context menu is initially hidden and can appear anywhere on the screen, instead of at the assigned, fixed position. The ContextMenu control is typically invoked when the user right-clicks a specific control; it pops up in response. Figure 6-23 shows a ContextMenu control in action.

key, they can directly use a symmetric encryption algorithm to start communicating. However, if they do not already share a symmetric key, they need to agree upon one. Alice and Bob also may not have access to an already secure communication channel, but might like to create one.
