Acerca de este producto
Product Information
Goppa codes are a class of linear codes and have a well defined algebraic structure. They are considered to be very close to random codes and form the basis of the Mc Eliece public key cryptosystem. Their true minimum distance and dimension are still not known. Neither do we know which choices of Goppa polynomials give rise to codes with better minimum distance. In this book we give an exact count of quintic irreducible Goppa codes of length 32 and their extended versions. We also present an instance of the problem of true minimum distance and choice of a Goppa polynomial. Apart from this, we give an example to show that the well known sufficient condition for two Goppa codes to be equivalent is not a necessary condition. We point out that it is possible to get such an example from among the degenerate codes but we show that the example we give is taken from the non-degenerate codes. We then give a count of degenerate and non degenerate codes.

- h***d (67)- Votos emitidos por el comprador.Últimos 6 mesesCompra verificadaReally good considering the age of it. Item received very well packaged. Just as described - ‘very good’. Would have been delivered within its due date but Royal Mail were to blame as they had it in the delivery office but didn’t send someone out to deliver that day. This is an issue with Royal Mail all the time so don’t always assume the seller didn’t send it. Good communication and highly recommend this seller.

It really adds to the “eBay experience”, restoring your faith in people/eBay sellers when you’ve found something you like, and having checked the description, you need more information, or simply clarification on something, you ask the question(s), the seller then responds with a promptly: filling in the gaps. A very smooth transaction. I would purchase from this seller again. Thank you.
