This only works if one instance of the PRNG is shared by multiple readers, rather than each reader operating in isolation. If there was a non-zero chance that an attacker could predict the next value, your PRNG was already broken. Two of the fundamental properties of a working PRNG is that if an attacker sees any number of outputs from the PRNG, the attacker cannot compute any previous values and the attacker cannot predict any future values. --Paul Hoffman _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-security To unsubscribe, send any mail to "[email protected]"
