RSS All releases of C++ Elliptic Curve Cryptography library

  •  20 Feb 2011 11:46

Release Notes: An anti-aliasing bug was fixed, which is needed when compiling this library with g++ 4.4 or higher. asm clobber bugs were fixed for 32-bit assembly.

  •  02 May 2008 10:53

Release Notes: The chapter "Cracking parameter b of the elliptic curve" has been extended. A formula is presented to calculate the number of points on y^2+xy=x^3+1 over GF(2^m) in O(m) time.

Release Notes: This release adds support for x86_64 and has some more ongoing bspace adventure added to the documentation.

  •  22 Nov 2006 00:56

Release Notes: This version brings the code completely up to date again with the latest of version of the working set (autoconf, compiler, etc.). The previous version was almost two years old and didn't even compile anymore.

Release Notes: This release extends the library to also work with reduction polynomials of degree five (pentanomials). A new method is presented to calculate the trace of an element of a binary field in constant time without the need of precalculation.

Release Notes: This release contains a major theoretical breakthrough. It brings the question of how much points there exist on an elliptic curve over a field of characteristic 2 back to the simple formula: Tr(x) = Tr(b/x^2)

Release Notes: This release added a few theory pages in which the elliptic curve parameter 'a' is fully analyzed and reduced to a single bit of significance. The added pages with general mathematical topics handle Frobenius and the Trace of an element of a field extension. There is also a new, though still 'hidden' page about Group Theory in this release. Two new methods have been added to the polynomial class: trace() and normal().

Release Notes: The brute force point counting data (of elliptic curves up to GF(2^10)) is presented and partly analysed. A start has been made in determining the relationship between the curve parameter 'a' and the structure of the elliptic curves. An in-depth theory page about the structure of Abelian groups was added. This release contains new code that allows one to determine the structure of the Abelian group from the count of points and their order as well as code that determines the normal of the hyperplane in the 'a-space' that represents curves with constant cardinality.

Release Notes: This release focuses on fixing major bugs. It fixes the point class and much of the documentation regarding it; it was totally broken.

Release Notes: This release adds a point class, representing a point on an elliptic curve. The theory page about the polynomial field GF(2^m) has been improved, and a new theory page about elliptic curves has been added.
