| Guidelines |
| The goal of the thesis is to evaluate the strength of the Acorn cipher using tools provided by the algebraic cryptanalysis. One of the possible methods is to express keystream bits as a set of algebraic equations, and then attempt to solve the equations by a SAT-solver. However, other methods may be used as well.
