Algebraic and quantum attacks on two digital signature schemes
Autor: Vitaly Roman’kov, Alexander Ushakov, Vladimir Shpilrain
Publikováno v: Journal of Mathematical Cryptology. 17
In this article, we analyze two digital signature schemes, proposed in Moldovyan et al., that use finite noncommutative associative algebras as underlying platforms. We prove that these schemes do not possess the claimed property of being quantum saf

Randomness and Complexity in Matrix Groups
Autor: Vladimir Shpilrain
Publikováno v: Journal of Mathematical Sciences. 257:919-925
We reflect on how to define the complexity of a matrix and how to sample a random invertible matrix. We also discuss a related issue of complexity of algorithms in matrix groups.

Delegating a Product of Group Exponentiations with Application to Signature Schemes (Submission to Special NutMiC 2019 Issue of JMC)
Autor: Vladimir Shpilrain, Giovanni Di Crescenzo, Delaram Kahrobaei, Matluba Khodjaeva
Publikováno v: Journal of Mathematical Cryptology, Vol 14, Iss 1, Pp 438-459 (2020)
Many public-key cryptosystems and, more generally, cryptographic protocols, use group exponentiations as important primitive operations. To expand the applicability of these solutions to computationally weaker devices, it has been advocated that a co

Efficient and Secure Delegation of Exponentiation in General Groups to a Single Malicious Server
Autor: Giovanni Di Crescenzo, Vladimir Shpilrain, Delaram Kahrobaei, Matluba Khodjaeva
Publikováno v: Mathematics in Computer Science. 14:641-656
Group exponentiation is an important and relatively expensive operation used in many public-key cryptosystems and, more generally, cryptographic protocols. To expand the applicability of these solutions to computationally weaker devices, it has been

Private naive bayes classification of personal biomedical data: Application in cancer data analysis
Autor: Vladimir Shpilrain, Kayvan Najarian, Delaram Kahrobaei, Alexander Wood
Publikováno v: Computers in Biology and Medicine. 105:144-150
Clinicians would benefit from access to predictive models for diagnosis, such as classification of tumors as malignant or benign, without compromising patients' privacy. In addition, the medical institutions and companies who own these medical inform
