Alphabetic scripts tend to have between 20 and 40 characters (Russian, for example, has 36 signs, and Arabic has 28).
Zimmermann believed that everybody deserved the right to the privacy that was offered by RSA encryption, and he directed his political zeal toward developing an RSA encryption product for the masses.
This apparently innocuous observation would lead to the first great breakthrough in cryptanalysis.
The Brotherhood was effectively a religious community, and one of the idols they worshiped was Number.
Similarly, if you’re trying to prove something mathematically, it’s possible that no proof exists.
Secret communication achieved by hiding the existence of a message is known as steganography
Scripts that rely on semagrams tend to have hundreds or even thousands of signs (Chinese has over 5,000).

Imagined a machine whose internal workings could be altered so that it could perform all the functions of all conceivable Turing machines. The alterations would be made by inserting carefully selected...
Zimmermann employed a neat trick that used asymmetric RSA encryption in tandem with old-fashioned symmetric encryption.
When ships carrying COMSEC material came into dock, crypto-custodians would march onboard, collect stacks of cards, paper tapes, floppy disks, or whatever other medium the keys might be stored on, and...
The three Britons had to sit back and watch as their discoveries were rediscovered by Diffie, Hellman, Merkle, Rivest, Shamir and Adleman over the next three years.
The mathematical life of a mathematician is short. Work rarely improves after the age of twenty-five or thirty. If little has been accomplished by then, little will ever be accomplished.
The first microdot to be spotted by the FBI was in 1941, following a tip-off that the Americans should look for a tiny gleam from the surface of a letter, indicative of smooth film.
The best random keys are created by harnessing natural physical processes, such as radioactivity, which is known to exhibit truly random behavior. The
Scientific proof is inevitably fickle and shoddy. On the other hand mathematical proof is absolute and devoid of doubt.
Q: What is the volume of a pizza of thickness a and radius z? 3 points A: pi.z.z.a
One of the features of the Enigma machine was its inability to encipher a letter as itself, which was a consequence of the reflector. The letter a could never be enciphered as A, the letter b could ne...
Most of the codebreakers returned to their civilian lives, sworn to secrecy, unable to reveal their pivotal role in the Allied war effort. While those who had fought conventional battles could talk of...
It is quite possible that British Intelligence demanded that Babbage keep his work secret, thus providing them with a nine-year head start over the rest of the world.
