404780fb4a2SCy Schubert# wpa_supplicant depends on strong random number generation being available
405780fb4a2SCy Schubert# from the operating system. os_get_random() function is used to fetch random
406780fb4a2SCy Schubert# data when needed, e.g., for key generation. On Linux and BSD systems, this
407780fb4a2SCy Schubert# works by reading /dev/urandom. It should be noted that the OS entropy pool
408780fb4a2SCy Schubert# needs to be properly initialized before wpa_supplicant is started. This is
409780fb4a2SCy Schubert# important especially on embedded devices that do not have a hardware random
410780fb4a2SCy Schubert# number generator and may by default start up with minimal entropy available
411780fb4a2SCy Schubert# for random number generation.
412780fb4a2SCy Schubert#
413780fb4a2SCy Schubert# As a safety net, wpa_supplicant is by default trying to internally collect
414780fb4a2SCy Schubert# additional entropy for generating random data to mix in with the data fetched
415780fb4a2SCy Schubert# from the OS. This by itself is not considered to be very strong, but it may
416780fb4a2SCy Schubert# help in cases where the system pool is not initialized properly. However, it
417780fb4a2SCy Schubert# is very strongly recommended that the system pool is initialized with enough
418780fb4a2SCy Schubert# entropy either by using hardware assisted random number generator or by
419780fb4a2SCy Schubert# storing state over device reboots.
420780fb4a2SCy Schubert#
421780fb4a2SCy Schubert# wpa_supplicant can be configured to maintain its own entropy store over
422780fb4a2SCy Schubert# restarts to enhance random number generation. This is not perfect, but it is
423780fb4a2SCy Schubert# much more secure than using the same sequence of random numbers after every
424780fb4a2SCy Schubert# reboot. This can be enabled with -e<entropy file> command line option. The
425780fb4a2SCy Schubert# specified file needs to be readable and writable by wpa_supplicant.
426780fb4a2SCy Schubert#
427780fb4a2SCy Schubert# If the os_get_random() is known to provide strong random data (e.g., on
428780fb4a2SCy Schubert# Linux/BSD, the board in question is known to have reliable source of random
429780fb4a2SCy Schubert# data from /dev/urandom), the internal wpa_supplicant random pool can be
430780fb4a2SCy Schubert# disabled. This will save some in binary size and CPU use. However, this
431780fb4a2SCy Schubert# should only be considered for builds that are known to be used on devices
432780fb4a2SCy Schubert# that meet the requirements described above.
