The knapsack cryptosystem invented by Merkle and Hellman is known to be broken with high probability
by the low density attack of Lagarias and Odlyzko (LO method). In this report, we made an investigation on the
following two things through computer experiments. (1) We sought relationship between properties of public-keys
for knapsack cryptosystems and success rate of the LO method, and (2) we proposed a few methods to improve the
basic LO method and verified their effectiveness. |
