SPHINCS: Practical Stateless Hash-Based Signatures
This paper introduces a high-security post-quantum stateless hash-based signature scheme that signs hundreds of messages per second on a modern 4-core 3.5GHz Intel CPU. Signatures are 41 KB, public keys are 1 KB, and private keys are 1 KB. The signature scheme is de signed to provide long-term 2 security even against attackers equipped with quantum computers. Unlike most hash-based designs, th...
متن کاملAnalysis of the Kupyna-256 Hash Function
The hash function Kupyna was recently published as the Ukrainian standard DSTU 7564:2014. It is structurally very similar to the SHA-3 finalist Grøstl, but differs in details of the round transformations. Most notably, some of the round constants are added with a modular addition, rather than bitwise xor. This change prevents a straightforward application of some recent attacks, in particular o...
متن کاملCryptanalysis of the Round-Reduced Kupyna Hash Function
The Kupyna hash function was selected as the new Ukrainian standard DSTU 7564:2014 in 2015. It is designed to replace the old Independent States (CIS) standard GOST 34.311-95. The Kupyna hash function is an AES-based primitive, which uses Merkle-Damg̊ard compression function based on Even-Mansour design. In this paper, we show the first cryptanalytic attacks on the round-reduced Kupyna hash func...
متن کاملA New Standard of Ukraine: The Kupyna Hash Function
The Kupyna hash function was approved as the new Ukrainian standard DSTU 7564:2014 in 2015. Main requirements for it were both high security level and good performance of software implementation on general-purpose 64-bit CPUs. The new hash function uses DaviesMeyer compression function based on Even-Mansour cipher construction. Kupyna is built on the transformations of the Kalyna block cipher (...
متن کاملSPHINCS-Simpira: Fast Stateless Hash-based Signatures with Post-quantum Security
We introduce SPHINCS-Simpira, which is a variant of the SPHINCS signature scheme with Simpira as a building block. SPHINCS was proposed by Bernstein et al. at EUROCRYPT 2015 as a hash-based signature scheme with post-quantum security. At ASIACRYPT 2016, Gueron and Mouha introduced the Simpira family of cryptographic permutations, which delivers high throughput on modern 64-bit processors by usi...
