release branch.
Changes between 1.1.0h and 1.1.1 [xx XXX xxxx]
+
+ *) Change generating and checking of primes so that the error rate of not
+ being prime depends on the intended use based on the size of the input.
+ For larger primes this will result in more rounds of Miller-Rabin.
+ The maximal error rate for primes with more than 1080 bits is lowered
+ to 2^-128.
+ [Kurt Roeckx, Annie Yousar]
+
+ *) Increase the number of Miller-Rabin rounds for DSA key generating to 64.
+ [Kurt Roeckx]
+
+ *) The 'tsget' script is renamed to 'tsget.pl', to avoid confusion when
+ moving between systems, and to avoid confusion when a Windows build is
+ done with mingw vs with MSVC. For POSIX installs, there's still a
+ symlink or copy named 'tsget' to avoid that confusion as well.
+ [Richard Levitte]
+
+ *) Revert blinding in ECDSA sign and instead make problematic addition
+ length-invariant. Switch even to fixed-length Montgomery multiplication.
+ [Andy Polyakov]
+
+ *) Use the new ec_scalar_mul_ladder scaffold to implement a specialized ladder
+ step for binary curves. The new implementation is based on formulas from
+ differential addition-and-doubling in mixed Lopez-Dahab projective
+ coordinates, modified to independently blind the operands.
+ [Billy Bob Brumley, Sohaib ul Hassan, Nicola Tuveri]
+
+ *) Add a scaffold to optionally enhance the Montgomery ladder implementation
+ for `ec_scalar_mul_ladder` (formerly `ec_mul_consttime`) allowing
+ EC_METHODs to implement their own specialized "ladder step", to take
+ advantage of more favorable coordinate systems or more efficient
+ differential addition-and-doubling algorithms.
+ [Billy Bob Brumley, Sohaib ul Hassan, Nicola Tuveri]
+
+ *) Modified the random device based seed sources to keep the relevant
+ file descriptors open rather than reopening them on each access.
+ This allows such sources to operate in a chroot() jail without
+ the associated device nodes being available. This behaviour can be
+ controlled using RAND_keep_random_devices_open().
+ [Paul Dale]
+
+ *) Numerous side-channel attack mitigations have been applied. This may have
+ performance impacts for some algorithms for the benefit of improved
+ security. Specific changes are noted in this change log by their respective
+ authors.
+ [Matt Caswell]
+
+ *) AIX shared library support overhaul. Switch to AIX "natural" way of
+ handling shared libraries, which means collecting shared objects of
+ different versions and bitnesses in one common archive. This allows to
+ mitigate conflict between 1.0 and 1.1 side-by-side installations. It
+ doesn't affect the way 3rd party applications are linked, only how
+ multi-version installation is managed.
+ [Andy Polyakov]
+
*) Make ec_group_do_inverse_ord() more robust and available to other
EC cryptosystems, so that irrespective of BN_FLG_CONSTTIME, SCA
mitigations are applied to the fallback BN_mod_inverse().
Some of its new features are:
o Support for multiple DRBG instances with seed chaining.
- o Add a public DRBG instance for the default RAND method.
- o Add a dedicated DRBG instance for generating long term private keys.
- o Make the DRBG instances fork-safe.
+ o The default RAND method makes use of a DRBG.
+ o There is a public and private DRBG instance.
+ o The DRBG instances are fork-safe.
o Keep all global DRBG instances on the secure heap if it is enabled.
- o Add a DRBG instance to every SSL instance for lock free operation
- and to increase unpredictability.
+ o The public and private DRBG instance are per thread for lock free
+ operation
