On Linux and BSD systems, this 407 1.1 christos # works by reading /dev/urandom. It should be noted that the OS entropy pool 408 1.1 christos # needs to be properly initialized before wpa_supplicant is started. This is 409 1.1 christos # important especially on embedded devices that do not have a hardware random 410 1.1 christos # number generator and may by default start up with minimal entropy available 411 1.1 christos # for random number generation. 412 1.1 christos # 413 1.1 christos # As a safety net, wpa_supplicant is by default trying to internally collect 414 1.1 christos # additional entropy for generating random data to mix in with the data fetched 415 1.1 christos # from the OS. This by itself is not considered to be very strong, but it may 416 1.1 christos # help in cases where the system pool is not initialized properly. However, it 417 1.1 christos # is very strongly recommended that the system pool is initialized with enough 418 1.1 christos # entropy either by using hardware assisted random number generator or by 419 1.1 christos # storing state over device reboots. 420 1.1 christos # 421 1.1 christos # wpa_supplicant can be configured to maintain its own entropy store over 422 1.1 christos # restarts to enhance random number generation. This is not perfect, but it is 423 1.1 christos # much more secure than using the same sequence of random numbers after every 424 1.1 christos # reboot. This can be enabled with -e<entropy file> command line option. The 425 1.1 christos # specified file needs to be readable and writable by wpa_supplicant. 426 1.1 christos # 427 1.1 christos # If the os_get_random() is known to provide strong random data (e.g., on 428 1.1 christos # Linux/BSD, the board in question is known to have reliable source of random 429 1.1 christos # data from /dev/urandom), the internal wpa_supplicant random pool can be 430 1.1 christos # disabled. This will save some in binary size and CPU use. However, this 431 1.1 christos # should only be considered for builds that are known to be used on devices 432 1.1 christos # that meet the requirements described above. 433 1.1.1.5 christos 434 1.1.1.5 christos # Wpa_supplicant's random pool is not necessary on Android.
