Differential Analysis of the Ternary Hash Function Troikader to be used inside IOTA’s distributed ledger but could also serve in all settings requiring the generation of ternary randomness. To be used in practice, Troika needs to be proven secure against state-of-the-art cryptanalysis. However, there are today almost no analysis tools for ternary designs.

Injective Rank Metric Trapdoor Functions with Homogeneous Errors The rank decoding problem which is the analogue of the problem of decoding a random linear code consists in recovering a basis of a random noise vector that was used to perturb a set of random linear equations sharing a secret solution. Assuming the intractability of this problem, we introduce a ne

: Persistent and Distributed Key Acquisition for Secure Storage from Passwordsraphic guarantees. Many IM users regularly change their devices and use multiple devices simultaneously, ruling out any long-term secret storage. Extending the end-to-end encryption guarantees from just message communication to also incorporate backups has so far required either some trust in an IM

Patient Zero & Patient Six: Zero-Value and Correlation Attacks on CSIDH and SIKEpand on such attacks by analyzing the behavior of the zero curve . and six curve . in CSIDH and SIKE. We demonstrate an attack on static-key CSIDH and SIKE implementations that recovers bits of the secret key by observing via zero-value-based resp. exploiting correlation-collision-based side-channel

An Effective Lower Bound on the Number of Orientable Supersingular Elliptic Curves order . inside their endomorphism ring. Prior to this work, the only known effective lower-bound is restricted to small discriminants. Our main result targets the case of fundamental discriminants and we derive a generic bound using the expansion properties of the supersingular isogeny graphs..Our
