In 2012, the present authors proposed a knapsack public-key cryptosystem using a random secret sequence, which will be referred to as MHK scheme.
MHK scheme has a remarkable feature that the public sequence is indistinguishable from
a uniform random sequence. However, in CSS2013, Nagao and Morii discovered that the plaintext of MHK scheme can be disclosed by computing an alternative solution, which is not equal to the genuine solution, with the conventional low-density attack. This attack will be referred to as alternative solution attack.
In this paper,we shall propose a new knapsack scheme using three random sequences, which is secure against the alternative solution attack. |
