Mathematical trapdoors in block ciphers: evaluation and attack exploitation

Date: 21-25 Settembre 2015

Luogo: Department of Mathematics, Univ. of Trento, Trento (ITALY).

Lab sessions: CryptoLabTN, Laboratorio di Matematica industriale e Crittografia

Lecturer: Prof. PHD M. Sala (Trento). Assistant Lecturer: PHD Marco Calderini.


In this full-immersion course we will show how mathematical trapdoors can be embedded in the design of a block cipher. We will show how the cipher be can evaluated to ensure that it is safe from these trapdoors. We will also show how an attacker can take advantage of the (knowledge of the) trapdoor, obtaining a complete break of the cipher in a way totally unexpected by the legitimate users.
