Abstract | ||
---|---|---|
This paper gives the definitions of a nonnormal super-increasing sequence and
a nonnormal subset sum separately, proves the two properties of a nonnormal
super-increasing sequence, and proposes the REESSE2+ public-key encryption
scheme which includes the three algorithms for key generation, encryption and
decryption. The paper discusses the necessity and sufficiency of the lever
function for preventing the Shamir extremum attack, analyzes the security of
REESSE2+ against extracting a private key from a public key through the
exhaustive search, recovering a plaintext from a ciphertext plus a knapsack of
high density through the LLL lattice basis reduction method, and heuristically
obtaining a plaintext through the meet-in-the-middle attack or the
adaptive-chosen-ciphertext attack. The authors evaluate the time complexity of
the REESSE2+ algorithms, compare REESSE2+ with ECC and NTRU, and find that the
encryption speed of REESSE2+ is ten thousand times faster than ECC and NTRU
bearing the matchable security, and the decryption speed of REESSE2+ is roughly
equivalent to ECC and NTRU respectively. |
