A new elliptic curve point compression method based on Fp-rationality of some generalized Kummer surfaces
elliptic cryptography point compression Barreto-Naehrig curves
2019/9/19
In the article we propose a new compression method (to 2log2(p)+32log2(p)+3 bits) for the Fp2Fp2-points of an elliptic curve Eb:y2=x3+bEb:y2=x3+b (for b∈F∗p2b∈Fp2∗) of jj-invariant ...
A New Method for Geometric Interpretation of Elliptic Curve Discrete Logarithm Problem
Intersection of Curves Grobner Basis Vanishing Ideals
2019/9/19
In this paper, we intend to study the geometric meaning of the discrete logarithm problem defined over an Elliptic Curve. The key idea is to reduce the Elliptic Curve Discrete Logarithm Problem (EC-DL...
Table Redundancy Method for Protecting against Differential Fault Analysis in the White-box Cryptography
Differential fault analysis white-box cryptography countermeasure
2019/8/26
Differential Fault Analysis (DFA) intentionally injects some fault into the encryption process and analyzes a secret key from the mathematical relationship between faulty and fault-free ciphertexts. E...
A Fast Characterization Method for Optical Fault Injection
Physical attacks Fault injection Fast space characterization
2019/7/26
Semi-invasive fault injection attacks, such as optical fault injection, are powerful techniques well-known by attackers and secure embedded system designers. When performing such attacks, the selectio...
Protecting ECC Against Fault Attacks: The Ring Extension Method Revisited
Elliptic curves formal groups degenerate curves
2019/5/21
Due to its shorter key size, elliptic curve cryptography (ECC) is gaining more and more popularity. However, if not properly implemented, the resulting cryptosystems may be susceptible to fault attack...
A Method to Reduce the Key Size of UOV Signature Scheme
digital signatures public-key cryptography
2019/5/13
Multivariate public key signature scheme has a good performance on speed and signature size. But most of them have a huge public key size. In this paper, we propose a new method to reduce the public k...
Cube attack is an important cryptanalytic technique against symmetric cryptosystems, especially for stream ciphers. The key step in cube attack is recovering superpoly. However, when cube size is larg...
Optimized Method for Computing Odd-Degree Isogenies on Edwards Curves
Isogeny Post-quantum cryptography Montgomery curves
2019/2/27
In this paper, we present an efficient method to compute arbitrary odd-degree isogenies on Edwards curves. By using the ww-coordinate, we optimized the isogeny formula on Edwards curves by Moody \text...
New Hybrid Method for Isogeny-based Cryptosystems using Edwards Curves
Isogeny Post-quantum cryptography Montgomery curves
2018/12/24
Along with the resistance against quantum computers, isogeny-based cryptography offers attractive cryptosystems due to small key sizes and compatibility with the current elliptic curve primitives. Whi...
