Inverses of $r$ -primitive $k$ -normal elements over finite fields

Mamta Rani, Avnish K. Sharma, Sharwan K. Tiwari +1

Let $r$ , $n$ be positive integers, $k$ be a non-negative integer and $q$ be any prime power such that $r ∣ q^{n} - 1.$ An element $α$ of the finite field $F_{q^{n}}$ is called…

An algebraic attack to the Bluetooth stream cipher E0

Roberto La Scala, Sergio Polese, Sharwan K. Tiwari +1

In this paper we study the security of the Bluetooth stream cipher E0 from the viewpoint it is a "difference stream cipher", that is, it is defined by a system of explicit differen…
