Algebraic Attack on HFE Revisited

2008
In this paper, we study how the algebraic attack on the HFE multivariate public key cryptosystem works if we build an HFE cryptosystem on a finite field whose characteristic is not two. Using some very basic algebraic geometry we argue that when the characteristic is not two the algebraic attack should not be polynomial in the range of the parameters ...

An Algebraic Broadcast Attack against NTRU

2012
In this paper, we propose an algebraic broadcast attack against NTRU, which recovers a single message encrypted multiple times using different NTRU public keys. Namely, when a message is broadcasted, under some reasonable assumptions, our attack can be completed in polynomial time and space.

Chosen IV algebraic attack on One.Fivium

2008 3rd International Conference on Intelligent System and Knowledge Engineering, 2008
One of the key questions in algebraic attacks is how to effectively reduce the degree of the function. Based on the algebraic attack, this paper presents a new algorithm of attack - chosen IV algebraic attack, which can reduce the function?s degree by choosing appropriate IV.

Algebraic Attack to SMS4 and the Comparison with AES

2009 Fifth International Conference on Information Assurance and Security, 2009
SMS4 is a 128-bit block cipher, which is used in the WAPI standard in China. This paper examines algebraic attacks on SMS4 over two different fields, that is, GF(2) and GF$(2^8),$ respectively. With regards to this, we first describe the SMS4 as systems of quadratic equations over the two different fields, and then estimate the computational ...

Meeting the Attacks on Algebra

The Mathematics Teacher, 1926
No subject in the high school curriculum, according to some educators, has yielded such unsatisfactory results as Algebra. It has been the subject of most severe criticisms on all sides, and has been held responsible for a great deal of freshman mortality. A leading educator of Massachusetts, in one of his public speeches, has expressed the desire that

An Improvement of Linearization-Based Algebraic Attacks

2011
In an algebraic attack on a cipher, one expresses the encryption function as a system (usually overdefined) of multivariate polynomial equations in the bits of the plaintext, the ciphertext and the key, and subsequently solves the system for the unknown key bits from the knowledge of one or more plaintext/ciphertext pairs.
