Changes between 0.9.7 and 0.9.8 [xx XXX 2002]
+ *) Add named elliptic curves over binary fields from X9.62, SECG,
+ and WAP/WTLS; add OIDs that were still missing.
+
+ [Sheueling Chang Shantz and Douglas Stebila
+ (Sun Microsystems Laboratories)]
+
+ *) Extend the EC library for elliptic curves over binary fields
+ (new files ec2_smpl.c, ec2_smpt.c, ec2_mult.c in crypto/ec/).
+ New EC_METHOD:
+
+ EC_GF2m_simple_method
+
+ New API functions:
+
+ EC_GROUP_new_curve_GF2m
+ EC_GROUP_set_curve_GF2m
+ EC_GROUP_get_curve_GF2m
+ EC_POINT_set_Jprojective_coordinates_GF2m
+ EC_POINT_get_Jprojective_coordinates_GF2m
+ EC_POINT_set_affine_coordinates_GF2m
+ EC_POINT_get_affine_coordinates_GF2m
+ EC_POINT_set_compressed_coordinates_GF2m
+
+ Point compression for binary fields is disabled by default for
+ patent reasons (compile with OPENSSL_EC_BIN_PT_COMP defined to
+ enable it).
+
+ As binary polynomials are represented as BIGNUMs, various members
+ of the EC_GROUP and EC_POINT data structures can be shared
+ between the implementations for prime fields and binary fields;
+ the above ..._GF2m functions (except for EX_GROUP_new_curve_GF2m)
+ are essentially identical to their ..._GFp counterparts.
+ (For simplicity, '..._GFp' prefix has been dropped from various
+ internal method names.)
+
+ An internal 'field_div' method (similar to 'field_mul' and
+ 'field_sqr') has been added; this is used only for binary fields.
+
+ [Sheueling Chang Shantz and Douglas Stebila
+ (Sun Microsystems Laboratories)]
+
+ *) Optionally dispatch EC_PONT_mul(), EC_POINT_precompute_mult()
+ through methods ('mul', 'precompute_mult').
+
+ The generic implementations (now internally called 'ec_wNAF_mul'
+ and 'ec_wNAF_precomputed_mult') remain the default if these
+ methods are undefined.
+
+ [Sheueling Chang Shantz and Douglas Stebila
+ (Sun Microsystems Laboratories)]
+
+ *) New function EC_GROUP_get_degree, which is defined through
+ EC_METHOD. For curves over prime fields, this returns the bit
+ length of the modulus.
+
+ [Sheueling Chang Shantz and Douglas Stebila
+ (Sun Microsystems Laboratories)]
+
+ *) New functions EC_GROUP_dup, EC_POINT_dup.
+ (These simply call ..._new and ..._copy).
+
+ [Sheueling Chang Shantz and Douglas Stebila
+ (Sun Microsystems Laboratories)]
+
*) Add binary polynomial arithmetic software in crypto/bn/bn_gf2m.c.
Polynomials are represented as BIGNUMs (where the sign bit is not
used) in the following functions [macros]:
[Sheueling Chang Shantz and Douglas Stebila
(Sun Microsystems Laboratories)]
- *) Add more WAP/WTLS elliptic curve OIDs.
- [Douglas Stebila <douglas.stebila@sun.com>]
-
*) Add new error code 'ERR_R_DISABLED' that can be used when some
functionality is disabled at compile-time.
[Douglas Stebila <douglas.stebila@sun.com>]
