Janos Follath 3332937538 Changelog: Add entry for prime test improvement 2018-10-09 16:33:27 +01:00
Janos Follath b8fc1b02ee RSA: Use MBEDTLS_MPI_GEN_PRIME_FLAG_LOW_ERR 2018-10-09 16:33:27 +01:00
Janos Follath a3cb7eb8ad Bignum: Add test for improved prime generation 2018-10-09 16:33:27 +01:00
Janos Follath f301d23ceb Bignum: Improve primality test for FIPS primes 
The FIPS 186-4 RSA key generation prescribes lower failure probability
in primality testing and this makes key generation slower. We enable the
caller to decide between compliance/security and performance.

This python script calculates the base two logarithm of the formulas in
HAC Fact 4.48 and was used to determine the breakpoints and number of
rounds:

def mrpkt_log_2(k, t):
    if t <= k/9.0:
        return 3*math.log(k,2)/2+t-math.log(t,2)/2+4-2*math.sqrt(t*k)
    elif t <= k/4.0:
        c1 = math.log(7.0*k/20,2)-5*t
        c2 = math.log(1/7.0,2)+15*math.log(k,2)/4.0-k/2.0-2*t
        c3 = math.log(12*k,2)-k/4.0-3*t
        return max(c1, c2, c3)
    else:
        return math.log(1/7.0)+15*math.log(k,2)/4.0-k/2.0-2*t

Janos Follath 7c025a9f50 Generalize dh_flag in mbedtls_mpi_gen_prime 
Setting the dh_flag to 1 used to indicate that the caller requests safe
primes from mbedtls_mpi_gen_prime. We generalize the functionality to
make room for more flags in that parameter.

Hanno Becker f5106d54eb Don't declare and define gmtime()-mutex on Windows platforms 2018-09-06 12:09:56 +01:00
Hanno Becker 323d8019bf Correct preprocessor guards determining use of gmtime() 
The previous code erroneously used gmtime_r() to implement
mbedtls_platform_gmtime() in case of a non-windows, non-unix system.

Hanno Becker 03b2bd4a06 Correct documentation of mbedtls_platform_gmtime_r() 
Previous documentation stated that gmtime_r() was from the standard library,
but it's POSIX.

Hanno Becker 6f70581c4a Correct POSIX version check to determine presence of gmtime_r() 
Recent versions of POSIX move gmtime_r to the base.

Hanno Becker 5a7fe14590 Don't include platform_time.h if !MBEDTLS_HAVE_TIME 
platform_time.h includes time.h, which is not assumed to be present
on a system where MBEDTLS_HAVE_TIME is not defined.

Hanno Becker cfeb70c6b9 gmtime: Remove special treatment for IAR 
Previous commits attempted to use `gmtime_s()` for IAR systems; however,
this attempt depends on the use of C11 extensions which lead to incompatibility
with other pieces of the library, such as the use of `memset()` which is
being deprecated in favor of `memset_s()` in C11.
