Postquantum Cryptography—State of the Art

2017 · IEEE Security & Privacy

Because of public-key cryptography’s relevance and quantum computers’ increasingly realistic threat to this technology, it’s necessary to come up with practical and secure postquantum cryptography. This special issue aims to present the state of the …

Computing Blindfolded on Data Homomorphically Encrypted under Multiple Keys: An Extended Survey

2020 · arXiv (Cornell University)

New cryptographic techniques such as homomorphic encryption (HE) allow computations to be outsourced to and evaluated blindfolded in a resourceful cloud. These computations often require private data owned by multiple participants, engaging in joint evaluation …

A Cryptographic Hash Function from Markoff Triples

2021 · arXiv (Cornell University)

Cryptographic hash functions from expander graphs were proposed by Charles, Goren, and Lauter in [CGL] based on the hardness of finding paths in the graph. In this paper, we propose a new candidate for a …
