In most password systems, the password typed by a user is sent in cleartext over the network to the computer that requested it This means that an intruder can spy on passing traf c to collect passwords Since users need to memorize their passwords, they typically select passwords that they can easily remember So, such passwords are selected from within a relatively small vocabulary, and are thus easily guessed by potential intruders [4] Of all authentication techniques that circumvent the drawbacks of passwords, the most promising ones are those using cryptographic means With such techniques, users are typically provided with smart cards or chip cards equipped with a processor capable of cryptographic operations Authentication is based upon using the card to compute or verify cryptographic messages exchanged with the computer.

When constructing a new dialog, you need to know the parent shell You can specify null for the parent shell, but this will prevent proper association of the dialog with its parent; if the dialog is modal as many dialogs are, then specifying the correct parent shell will prevent the user from being able to activate the parent window before closing the dialog So the question becomes how to obtain the parent shell IWorkbenchWindowActionDelegate (see example code in Section 626) If you have an action delegate, then Eclipse provides the workbench window from which a shell can be obtained Immediately after the action delegate is instantiated, Eclipse calls the init( ) method with the work-

bench window as the argument Cache this window and pass the window s shell as an argument when constructing your dialog:

Therefore, the bitwise AND of the two values in Figure 34 would be the bit-by-bit comparison of bits in the first operand (12) with the bits in the second operand (7), resulting in the binary value 000000100, which is 4 Alternatively, a bitwise OR of the two values would produce 00001111 , the binary equivalent of 15 The XOR result would be 00001011 , or decimal 11

Cryptographic authentication consists of challenging the user or communicating party being authenticated to prove its identity by demonstrating its ability to encipher or decipher some item with a secret or private key known to be stored inside the smart card Of course, since the secret or private key stored on the card or secure device changes infrequently, the item to be enciphered or deciphered with it must change for every execution of the authentication protocol, otherwise, even though the secret never ows in cleartext over the network, an intruder could still tap a line, record the cryptic message that ows over it, and play that recording back at a later time without even knowing what it means To guarantee that the item that gets enciphered (or deciphered), called the challenge, is different for every execution of the authentication protocol, three techniques are used.

private IWorkbenchWindow window; public void init(IWorkbenchWindow window) { thiswindow = window; } public void run(IAction action) { Shell parentShell = windowgetShell(); MyDialog dialog = new MyDialog(parentShell, ); etc }

IObjectActionDelegate (see Section 633) If you have a action in a context menu, the Eclipse provides the target part from which a shell can be obtained Before the run( ) method is called, Eclipse calls setActivePart( ) with the target part Cache this part and pass the shell containing the part as an argument when constructing your dialog:

Listing 337 demonstrates how to use these bitwise operators The results of Listing 337 appear in Output 318

The challenge may be derived either from a real-time clock reading, in which case it is called a timestamp, from a counter that is incremented for every protocol execution, or from a random number generator, in which case it is called a nonce In any case, a new challenge (timestamp, counter value or nonce) is generated for each protocol run With timestamps, the user being authenticated, A, enciphers the current reading of its clock and sends the result to the party requesting the authentication B B then deciphers the received message, and veri es that the timestamp corresponds to the current realtime The drawback of timestamps is thus immediately apparent A and B must have synchronized real-time clocks for the veri cation to be possible.

private IWorkbenchPart targetPart; public void setActivePart(IAction action, IWorkbenchPart targetPart) { thistargetPart = targetPart; } public void run(IAction action) { Shell parentShell = targetPartgetSite()getShell(); MyDialog dialog = new MyDialog(parentShell, ); etc }
