Deterministic Constructions of 21-Step Collisions for the SHA-2 Hash Familykolić and Biryukov, for finding collisions for 21-step SHA-256 holds with probability 2.. No results on 21-step SHA-512 are previously known. Further, we provide evidence that the Nikolić-Biryukov differential path is unlikely to yield 21-step collisions for SHA-512.

Proxy Re-signatures in the Standard Modelsecure under standard assumption in the standard model. We also discuss how to incorporate the concept of forward-security into the proxy re-signature paradigm, such that the signing and the transformation are both time-limited.

Property-Based Attestation without a Trusted Third Party such a TTP. We define a formal model, propose an efficient protocol based on the ideas of ring signatures, and prove its security. The cryptographic technique deployed in our protocol is of independent interest, as it shows how ring signatures can be used to efficiently prove the knowledge of an element in a list without disclosing it.
