For more than 20 years, the Cryptology ePrint Archive has been publishing pre-print papers relevant to the field of cryptology. You can read more about our goals and history, see our …

The Cryptology ePrint Archive provides rapid access to recent research in cryptology. Papers have been placed here by the authors and did not undergo any refereeing process other than …

In this respect, the papers in the Cryptology ePrint Archive have the status of technical reports. Papers submitted may be author versions of published papers if the copyright holder allows …

Feb 5, 2025 · Note: Acknowledgement Updated. We've noticed a recent work (https://eprint.iacr.org/2025/892) that claims to break QA-SD assumptions under serveal …

Dec 4, 2024 · Existing post-quantum folding schemes (Boneh, Chen, ePrint 2024/257) based on lattice assumptions instead are secure under structured lattice assumptions, such as the …

Mar 25, 2023 · We introduce SQIsignHD, a new post-quantum digital signature scheme inspired by SQIsign. SQIsignHD exploits the recent algorithmic breakthrough underlying the attack on …

Feb 19, 2025 · We address the problem of proving the validity of computation on ciphertexts of homomorphic encryption (HE) schemes, a feature that enables outsourcing of data and …

Feb 15, 2024 · We revisit the construction of signature schemes using the MPC-in-the-head paradigm. We obtain two main contributions: – We observe that previous signatures in the …

Feb 16, 2025 · Abstract We introduce a general template for building garbled circuits with low communication, assuming decisional composite residuosity (DCR) and a circular security …
