Hamming, Golay, cyclic, BCH, Reed-Solomon, etc. Cryptography page Pari . Here is the factorization of the product of two big primes. My implementation of the index calculus algorithm for computing discrete logs is now on the web. Seminar topics .
Linear code bounds .
Home page of T. Satoh with reference to his paper with Araki on discrete logs for anomalous elliptic curves. You can access Pari interactively here . Note that this page is still under development and requires netmath to be viewed in full glory. The previous link will lead you to a page from which you can download netmath as a standalone program. If you want, it is possible but not recommended, to view netmath under netscape by going here , but you'll need some plug-ins in your browser.
