In our previous blog post (Part 1 of our key replication series), Automatically replicate your card payment keys across AWS Regions, we explored an event-driven, serverless architecture using AWS PrivateLink to securely replicate card payment keys across AWS Regions. That solution demonstrated how to build a custom replication framework …
RSA Conference (RSAC) 2025 drew 730 speakers, 650 exhibitors, and 44,000 attendees from across the globe to the Moscone Center in San Francisco, California from April 28 through May 1. The keynote lineup was eclectic, with 37 presentations featuring speakers ranging from NBA Hall of Famer Earvin “Magic …
On August 20, 2024, we announced the general availability of the new AWS CloudHSM instance type hsm2m.medium (hsm2). This new type comes with additional features compared to the previous AWS CloudHSM instance type, hsm1.medium (hsm1), such as support for Federal Information Processing Standard (FIPS) 140-3 Level 3 …
The UK’s National Cyber Security Centre just released its white paper on “Advanced Cryptography,” which it defines as “cryptographic techniques for processing encrypted data, providing enhanced functionality over and above that provided by traditional cryptography.” It includes things like homomorphic encryption, attribute-based encryption, zero-knowledge proofs, and secure multiparty …
This is a truly fascinating paper: “ Trusted Machine Learning Models Unlock Private Inference for Problems Currently Infeasible with Cryptography.” The basic idea is that AIs can act as trusted third parties: Abstract: We often interact with untrusted parties. Prioritization of privacy can limit the effectiveness of these interactions, as …
The UK’s National Computer Security Center (part of GCHQ) released a timeline —also see their blog post —for migration to quantum-computer-resistant cryptography. It even made The Guardian. [...]
Interesting article —with photos!—of the US/UK “Combined Cipher Machine” from WWII. [...]
Interesting research: “ How to Securely Implement Cryptography in Deep Neural Networks.” Abstract: The wide adoption of deep neural networks (DNNs) raises the question of how can we equip them with a desired cryptographic functionality (e.g, to decrypt an encrypted input, to verify that this input is authorized, or …
