...today's world, the integrity of secret messages can be crucial not only to national security but to commercial and industrial operations as well. Yet as society becomes increasingly reliant on electronically relayed communications-and more sophisticated new gadgetry is developed to intercept them-it is becoming harder than ever to keep a transmitted secret. But now the code breakers may finally have met their match. As a result of recent work by Stanford University scientists, ciphers that are for all practical purposes unbreakable can be produced easily. Says Scientific American Mathematics Columnist Martin Gardner: "The breakthrough bids fair...
...message. On the contrary, the encrypting key could well be made public in a handbook like a telephone directory. In that way, someone who wanted to communicate with the group would simply look up the necessary key and use it to encode a message. Yet even if someone could intercept this transmission, he could not interpret it without access to the second, or decoding, key. Diffie compares this seemingly paradoxical system to a bank's night-deposit box: anyone can put money in, but only authorized employees can take...
...Betsy will probably be rock-bottom for Laurence Olivier; let us hope in the future that he accepts projects that will not mock the accomplishments of a heroic career. Maybe a legion of his fans could from a club to intercept and screen all scripts before they reach him, discarding Harold Robbins and Ira Levin in the process. But then again, in accepting the role of Loren Hardeman, Olivier accepted the challenge of a role unlike any he had done before. At age 70, Laurence Olivier still has enough daring to teach us all a lesson...
...Soviets are listening to every word. Using innocent-looking vans or "ferret" satellites or balloon-supported towlines, trailing from submarines, that act as 2,000-ft. antennas, the Russians pick up microwave transmissions from telephones, radios and satellites. Last year they installed huge eavesdropping antennas near Havana to intercept messages sent from the U.S. overseas. At KGB headquarters in Moscow, 30,000 workers specialize in computer analysis of miles of taped transmissions. The U.S. can scarcely complain; some 4,000 Americans employed by the National Security Agency, CIA, Defense Intelligence Agency and secret private contractors are doing exactly the same...
What triggers the bolt, says Follin, are particles in the secondary cosmic showers called muons, which increase the charge with fresh electron avalanches. Finally, electrons burst from the cloud along a path of ionized (electrically charged) air. As other muons intercept the path at different angles, forming new trails, the electrons follow a jagged, steplike route to the ground...
