A possible intrinsic weakness of AES and other cryptosystems
Anna Rimoldi, Massimiliano Sala, Ilia Toli
It has been suggested that the algebraic structure of AES (and other similar block ciphers) could lead to a weakness exploitable in new attacks. In this paper, we use the algebraic…
Singularity of Sparse Circulant Matrices is NP-complete
Ilia Toli
It is shown by Karp reduction that deciding the singularity of sparse circulant matrices (SC problem) is NP-complete. We can write them only implicitly…
Cryptanalysis of HFE
Ilia Toli
I transform the trapdoor problem of HFE into a linear algebra problem.
Hidden Polynomial(s) Cryptosystems
Ilia Toli
We propose public-key cryptosystems with public key a system of polynomial equations, algebraic or differential, and private key a single polynomial or a small-size ideal. We set u…
Hidden Polynomial(s) Cryptosystems
Ilia Toli
We propose variations of the class of hidden monomial cryptosystems in order to make it resistant to all known attacks. We use identities built upon a single bivariate polynomial e…
