Computational searches for quadratic APN functions with subfield coefficients
(Master thesis, 2023-06-01)Almost perfect nonlinear (APN) functions are important in fields such as algebra, combinatorics, cryptography, etc. Finding new APN functions is of special importance in cryptography. This is because when used in modern ... -
Deanonymizing communications on The Onion Router (TOR) network with Deep Learning
(Master thesis, 2021-06-01)Staying anonymous on the Internet is becoming increasingly difficult. Advertisements for services that to some extent offer privacy are frequent, and the general population seems to be more aware of privacy than previously. ... -
Grein. A New Non-Linear Cryptoprimitive
(Master thesis, 2013-12-10)In this thesis, we will study a new stream cipher, Grein, and a new cryptoprimitive used in this cipher. The second chapter gives a brief introduction to cryptography in general. The third chapter looks at stream ciphers ... -
Symmetric Ciphers for Fully Homomorphic Encryption
(Master thesis, 2020-08-28)Fully homomorphic encryption is the latest addition to the world of cryptography. It is a type of encryption that allows operations to be done on ciphertexts, which is not possible with traditional encryption. The field ... -
Thickness Distribution of Boolean Functions in 4 and 5 Variables
(Master thesis, 2020-05-12)This thesis explores the distribution of algebraic thickness of Boolean functions in four and five variables, that is, the minimum number of terms in the ANF of the functions in the orbit of a Boolean function, through all ...
