If you re looking for something to produce a representative of a larger amount of data, it s easy to see that a message digest does that job fairly well. First, the output of a digest algorithm is usually smaller than the data itself, and no matter how big the data gets, the digest as a representative will always be the same size. If someone tries to surreptitiously change the original message, the new, fake message will not produce the same digest. If the digest produced by the algorithm does not represent the data, you know that something went wrong (see Figure 5-7). Maybe the data has been altered, maybe the digest is wrong. You might not know what exactly happened, but you do know something happened. Here s how an application can check a digest. Pao-Chi is sending Daniel some data, such as an e-mail or a contract; for this example, it s the message about selling four units to Satomi. Before Pao-Chi sends the message, he digests it. Now he sends the data and the digest. When Daniel gets the data, he also digests it. If his digest matches Pao-Chi s, he knows the data has not been changed in transit. If Satomi had intercepted and altered the message, the digest that Daniel produced would not have matched the digest Pao-Chi produced. Daniel would know that something happened and would not trust the data. Your immediate response might be, If Satomi could alter the data, she could alter the digest. That s true, but there are two ways to prevent that. One is to use a digital signature, a topic we ll return to shortly. For now, let s look at the second way: a keyed digest. The most common keyed digest is called HMAC.

The ultrasonic receiver section (see Fig. 5.35) is used to fine-tune the transmitter. The ultrasonic transducers resonate at 40 kHz. If the resonant frequency varies too much ( 750 Hz), the performance of the transducers degrades rapidly. Fine-tuning the transmitter for optimum resonance frequency is not difficult provided you follow the procedure outlined. The only piece of equipment needed is a volt-ohm milliammeter (VOM) capable of reading 2 VDC.

rent time value in seconds and then subtracting it from a later time value in seconds. What may occur if the time happens to be 23:59:59 when we start the timer and we check the elapsed time say 30 seconds later Can you allow for this with a more robust subroutine

MAC stands for message authentication checksum (or message authentication code), and H stands for hash or hash-based function, so an HMAC

HINT: Thirty seconds later the time would be 00:00:29. How does this affect the new time value Check out the functions Date() and Timer(). Why is it that the use of the command Delay would not work

Mwrite/WriteScr save your arrays and screen les to give them to a user who then uses MRead/ReadScr to recreate the arrays and screen without having to know the details of how they were created. The arrays of importance are Nodes[ ] and MapGraph[ ], also the counter NodesCount has to be recreated after reading the arrays from the les.

(pronounced aitch mac ) is a hash-based message authentication algorithm A checksum is an algorithm that checks data by summing it Suppose you had a column of numbers (say, in an accountant s ledger) If the correct numbers are there, the sum of the column is a specific value Later, to check that the ledger is still correct, you don t compare each number individually; rather, you find the sum of the column If the second sum matches the first sum, the check passes Of course, if someone can change one number, it s easy also to change the sum at the bottom of the ledger so that it matches the change in the single number It would also be easy to change another number in the column to offset the first change A MAC is a way to detect changes in the data or in the sum.

HINT:

To detect changes in the data, a MAC can be based on a digest, block cipher, or stream cipher (see 2) To detect changes in the actual checksum, the MAC uses a key Most HMACs work this way Two parties share a secret key ( 4 shows how that s done), and then each digest the key and message The digest depends on the message and the key, so an attacker would have to know what the key is to alter the message and attach a correct checksum For example, suppose Pao-Chi sends Daniel message 1 shown earlier (the message instructing him to ship four units to Satomi) Pao-Chi uses an HMAC so that Daniel can verify that the data did not change Using a key exchange algorithm (RSA, DH, ECDH), the two agree on a 128-bit key.
