Attacks upon factoring, and individual tests, whether first-time or doublecheck, while certainly possible, only delay the project. They can not result in a corrupt database. However, the project is also vulnerable to attacks upon the doublechecking *system*, for example, an attacker could connive to submit a concocted result twice for the same exponent, both as a first-time test and as a doublecheck. From previous discussions, I know that this is not trivial, but it remains feasible. > Regards > Brian Beesley Daran _________________________________________________________________________ Unsubscribe & list info -- http://www.ndatech.com/mersenne/signup.htm Mersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers
