Hugo Krawczyk wrote a pretty good paper about how these LCGs can be predicted ("How to predict congruential generators"). If you're lucky and interested, you may still find a free, downloadable version of it on the web. And there's plenty more research that clearly shows that you should never use an LCG … Visualizza altro The assumption that an attacker would have to wait for the LCG to repeat after a full cycle is wrong. Even with an optimal cycle (the … Visualizza altro Replace your current code. Use SecureRandom exclusively. Then at least you will have a little guarantee that the result will be hard to predict.
