A Wireguard fejlesztője jelentősen felgyorsította a getrandom() hívást a Linux rendszerben
Jason Donenfeld, the author of the WireGuard VPN, has introduced patches that significantly speed up the acquisition of random numbers from the system via the getrandom() function, implemented through the corresponding Linux system call. The advantage of this solution over using /dev/random or /dev/urandom is its immunity to file descriptor exhaustion attacks, which can lead to uninitialized and non-random cryptographic keys. The proposed optimization is based on […]
