Welcome to the Real World Cryptography Paris (RWC Paris) Meetups! Our goal is to bring together enthusiasts, professionals, and academics to discuss the latest advancements in cryptography. Whether you're an experienced cryptographer, a software engineer, or someone with a keen interest in the field, our meetups offer a platform to learn, share, and network.
Real World Cryptography Paris meetups are made possible by the following sponsors, who work together to organize the event, provide a venue, review and select talks, and more.
Yanis, PSE
This talk introduces Trinity, a cryptographic protocol enabling one-round two-party computation (2PC) with zero-knowledge verified inputs. We’ll outline the core problem of securely verifying private inputs in minimal interaction settings, present our solution combining garbled circuits and Laconic OT over KZG, and explore practical use cases like threshold signatures, privacy-preserving identity proofs, and collaborative ZK apps.
19:15Julio Loayza Meneses, Quarkslab
We present crypto-condor, an open-source Python library to test cryptographic primitives. It provides a Python API and a CLI to test that implementations are compliant to the standard using test vectors. It comes with a detailed documentation that includes guides on the primitives supported. These guides offer an overview of the primitive along with a list of the rules and recommendations by the ANSSI pertaining the primitive. crypto-condor supports widely used primitives (AES, ECDSA, RSA, ...) as well as the post-quantum primitives selected by the NIST.
19:35Sylvain Rieutord, Cosmian
The last years have seen the emergence of Searchable Symmetric Encryption (SSE) schemes. While SSE is well-suited for exact search, for exact-matching of specific keywords, it seems hard to make it work for approximate searches. On the other hand, we are now used to ask queries in natural language, which can be an ultimate goal on encrypted data.
19:55Nadim Kobeissi, Symbolic Software & Cure53
Privacy networks and cryptographic infrastructures are only as strong as their weakest links. In this talk, Nadim Kobeissi will present key findings from Cure53’s latest security audit of Nym, a decentralized privacy network. The audit uncovered critical vulnerabilities, including signature forgery in the Pointcheval-Sanders scheme, BLS12-381 EC signature bypasses, nonce-key reuse in AES-CTR, and double-spend attacks in offline eCash.

20:35RWC Paris Meetups aims to be a friendly place for people with common interests to meet up and talk about real world cryptography. Everyone who attends promises to treat everyone with dignity and respect to be considerate and understanding of differing viewpoints, and to be respectful in all forms of communication.
