Maria Naya-Plasencia ==================== Title: Overview of lightweight primitives: design and cryptanalysis Abstract: In order to answer the requirements raised by a large number of applications, the design of lightweight primitives has become a major interest of the cryptographic community. A (very) large number of lightweight block ciphers have been proposed. Correctly evaluating their security has become a primordial task requiring the attention of our community. In this talk we will make a survey of these proposed ciphers, their possible classifications, some of the proposed cryptanalysis and their actual status.
