Description
RFID tags are tiny computational devices with no internal source of power, which are likely to be deployed in a large number of applications in the next few years. In this talk I will describe several light weight security algorithms which were designed specifically for such devices, and in particular a new hash function called SQUASH which is provably at least as one-way as the Rabin scheme. It can be implemented with a very small number of gates on RFID tags, and it is extremely fast on larger processors with arbitrary word sizes.

Algorithms for post-quantum commutative group actions
Speaker : Marc Houben - Inria Bordeaux
At the historical foundation of isogeny-based cryptography lies a scheme known as CRS; a key exchange protocol based on class group actions on elliptic curves. Along with more efficient variants, such as CSIDH, this framework has emerged as a powerful building block for the construction of advanced post-quantum cryptographic primitives. Unfortunately, all protocols in this line of work are[…] -
Endomorphisms via Splittings
Speaker : Min-Yi Shen - No Affiliation
One of the fundamental hardness assumptions underlying isogeny-based cryptography is the problem of finding a non-trivial endomorphism of a given supersingular elliptic curve. In this talk, we show that the problem is related to the problem of finding a splitting of a principally polarised superspecial abelian surface. In particular, we provide formal security reductions and a proof-of-concept[…]-
