Public-Key Encryption Schemes with Auxiliary Inputs
We construct public-key cryptosystems that remain secure even when the adversary is given any computationally uninvertible function of the secret key as auxiliary input (even one t...

Multidimensional Extension of Matsui's Algorithm 2
Matsui’s one-dimensional Alg. 2 can be used for recovering bits of the last round key of a block cipher. In this paper a truly multidimensional extension of Alg. 2 based on estab...

A secure variant of the Hill Cipher
The Hill cipher is a classical symmetric encryption algorithm that succumbs to the know-plaintext attack. Although its vulnerability to cryptanalysis has rendered it unusable in p...

A New Variant of the Cramer-Shoup KEM Secure against Chosen Ciphertext Attack
We propose a new variant of the Cramer-Shoup KEM (key encapsulation mechanism). The proposed variant is more efficient than the original Cramer-Shoup KEM scheme in terms of public...

Novel Precomputation Schemes for Elliptic Curve Cryptosystems
We present an innovative technique to add elliptic curve points with the form P Q± , and discuss its application to the generation of precomputed tables for the scalar multiplicat...
