Extractions: Remembering our experience with multiplicative ciphers, we know that these numbers are all different modulo p . That is, modulo p , these are precisely all the numbers from 1 to p Here is the trick! Multiply all the numbers together and the result must be the same as multiplying all the numbers from 1 to p -1. Thus,

http://www.dozenalsociety.org.uk/numbers/fermat.html

Extractions: Some students are puzzled on reading that such and such a (large) number is composite but its factors are not known. Books in which such statements appear - and there are quite a few of them in the 'popular' mathematics field - should include a few lines to explain how this can be true. Fermat's theorem states that if p is a prime and a is not a multiple of p, then (a p-1 -1) is a multiple of p. Or in congruence language a p-1 = 1 (mod p). Though this is true we may not infer that the converse is necessarily true, namely that if a n-1 = 1 (mod n) then n must be prime. This n may very well be prime, but there are many composite numbers which satisfy the congruence. Lucas first laid down the necessary conditions for a true converse of the theorem, namely that

Extractions: Welcome to one of the most fascinating areas of mathematics. There's a fair amount of work involved in understanding even approximately how the recent proof of this theorem was done, but if you like mathematics, you should find it very rewarding. Please let me know by email how you like these pages. I'll fix any errors, of course, and try to improve anything that is too unclear. If you have ever read about number theory you probably know that (the so-called) Fermat's Last Theorem has been one of the great unsolved problems of the field for three hundred and fifty years. You may also know that a solution of the problem was claimed very recently - in 1993. And, after a few tense months of trying to overcome a difficulty that was noticed in the original proof, experts in the field now believe that the problem really is solved. In this report, we're going to present an overview of some of the mathematics that has either been developed over the years to try to solve the problem (directly or indirectly) or else which has been found to be relevant. The emphasis here will be on the "big picture" rather than technical details. (Of course, until you begin to see the big picture, many things may look like just technical details.) We will see that this encompasses an astonishingly large part of the whole of "pure" mathematics. In some sense, this demonstrates just how "unified" as a science mathematics really is. And this fact, rather than any intrinsic utility of a solution to the problem itself, is why so many mathematicians have worked on it over the years and have treated it as such an important problem.

Extractions: To prove Euler's theorem, fix and consider all its powers (under multiplication ). Since is a finite set, there are only finitely many distinct powers. Denote this set by . Let be the number of elements of . Obviously, . Now define an equivalence relation: iff for some integer . Let be the equivalence class of under this relation. It is easy to see that has exactly the same number of elements as , i.e. . Hence is a multiple of . Since , it follows that as well. We study the structure of Euler's function further. Recall that is the set of equivalence ( ) classes of integers relatively prime to . Alternatively, by picking a representative from each class, in a way that this representative is between and , we think of as a so-called reduced set of residues . If , there is a natural one-to-one correspondence between and . This is defined by the function

Extractions: Fermats Last Theorem dominated my own life for four years, because I made a TV documentary, wrote a book and then lectured on the subject. Getting involved in Fermats mischievous conundrum set me on the path towards being an author and ignited an interest in mathematics that has continued ever since. As a physicist, I was always interested in mathematics as a tool for studying the universe, but learning about Fermats Last Theorem taught me to love mathematics for its own sake. There is a Mathematics Corner currently being developed for this site.

Extractions: Public-key cryptography With the growth of electronic communications, privacy has become a significant issue on the Internet. There is a newsgroup alt.privacy , a vast literature on anonymous email , and services like The Anonymizer and IDzap that offer anonymous World-Wide Web surfing. Average computer users would likely be satisfied with the capability of putting their email in an envelope. In the ordinary course of events, email is more like a postcard: it can easily be read in passing. Private email is now widely and freely available through public-key cryptography To use classical ciphers, the sender and recipient must exchange a common key ahead of time. The idea behind public-key cryptography is that one key can be used to encode a message, and a different key can be used to decode the message. A user can make public one of a pair of complementary keys to enable the world to send enciphered messages that can be deciphered only by that user. Also, the user can broadcast enciphered messages that everyone can decipher and verify as coming from that user. Thus, public-key cryptography simultaneously meets the goals of privacy and of authentication. The first mathematical implementation of a public-key cryptosystem was published by R. L. Rivest
