Cryptography FM is a weekly podcast with news and a featured interview covering the latest developments in theoretical and applied cryptography. Whether it's a new innovative paper on lattice-based cryptography or a novel attack on a secure messaging protocol, we'll get the people behind it on Cryptography FM to talk about it with your host, Nadim Kobeissi.

post-quantum cryptography, signature schemes
Serious weaknesses are uncovered in one of NIST's post-quantum cryptography finalists. Ward Beullens joins us to talk about his new research and more.

Ange Albertini and Stefan Kölbl discuss how new research from Google, the University of Haifa and Amazon is exploiting authenticated encryption to make a PDF decrypt into... a different PDF. And much more.

Sofía Celi of Cloudflare talks about the latest version of Off-the-Record secure messaging protocol, why deniability is important, and more.

elliptic curve cryptography, side channel attacks
LadderLeak is a new attack that exploits side channels present in ECDSA, claiming to allow real-world breaking of ECDSA with less than a bit of nonce leakage. But what does “less than a bit” mean in this context? Is LadderLeak really that effective at breaking ECDSA, with so little information to go on? Joining us this episode are LadderLeak co-authors Akira Takahashi, Mehdi Tibouchi and Yuval Yarom to discuss these questions and more.

Raphael Robert from Wire talks about how MLS wants to scale secure messaging to groups with hundreds or even thousands of participants.

Dr. David Archer of Galois discusses using zero-knowledge proof in order to prove the existence (or lack of) a software vulnerability without sharing details about the vulnerability itself.

Luca Deo Feo and Hart Montgomery try to explain isogeny-based cryptography to Nadim.

Formal verification has been used to prove the security of cryptographic protocols like Signal and TLS – but can it also be used to verify the correctness of legislation? Denis Merigoux tells us about how Catala wants to use formal methods to verify the French tax code.

Jack O'Connor and Jean-Philippe Aumasson discuss how Merkle Trees make the new BLAKE3 hash function special, and talk about the design process for the BLAKE family of hash functions in general.

Léo Perrin talks about how his team at INRIA was able to find serious breaks in the Gimli family of lightweight symmetric primitives, and why NIST's lightweight cryptography competition even matters in the first place, especially with block ciphers like AES dominating the industry.

KEMTLS is a modified version of TLS 1.3 that uses Key Encapsulation Mechanisms, or KEMs, instead of signatures for server authentication, thereby providing a sort of “post-quantum TLS”. But what even are KEMs? Are quantum computers even a thing that we should be worried about? On the first ever episode of Cryptography FM, we’ll be hosting Dr. Douglas Stebila and PhD Candidate Thom Wiggers to discuss these questions and more.
