Annihilators through fault injection analysis on selected stream ciphers

Algebraic attacks on stream cipher are important in cryptanalysis to both design- ers and attackers. Generally, complexity of an algebraic attack will increase as the degree of an equation increases. In conducting this attack, we aim to decrease the degree of the targeted boolean equation by...
