Current analysis on payment security, fraud prevention, AML/KYC, and PCI DSS compliance.
Cryptography FundamentalsYour payment authentication layer is vulnerable to a threat that doesn t exist yet. Quantum adversaries can harvest encrypted authentication sessions today and decrypt them once quantum computers matu
Cryptography FundamentalsPurpose of the Template You re tasked with securing payment systems against both current threats and future quantum computers that could compromise RSA and elliptic-curve cryptography. This template p
Cryptography FundamentalsWhen your decryption committee members can profit from revealing their shares, your threat model changes. Traditional static and adaptive corruption models assume parties are compromised by external a
Cryptography FundamentalsYou ve chosen an ARX-based cipher because it s fast, software-friendly, and grounded in strong cryptographic principles. Your team relies on it to protect payment sessions, encrypt cardholder data in

Cryptography FundamentalsThe Challenge Your white-box cipher implementation is part of a payment application, designed to protect cryptographic keys in an environment where attackers control the host. You ve fortified it agai
Cryptography FundamentalsThe Challenge A proposed lightweight 128-bit blockcipher called MERIDIAN was evaluated as an alternative to AES for resource-constrained environments. The designers claimed it offered adequate securit
Cryptography FundamentalsEvery few years, a paper promises to upend cryptographic security. Headlines scream: New Algorithm Threatens Encryption, Post-Quantum Defenses Under Attack. Your compliance team starts asking question
Cryptography FundamentalsSide-channel attacks have become cheaper and faster. A new attack framework recovered cryptographic secrets from an ARM Cortex-M4 device in just 15 minutes with a single power trace. This isn t a theo
Cryptography FundamentalsYour Hardware Security Module s cipher claims 128-bit security. Recent cryptanalysis shows the actual protection level might be 86 bits. That s not a rounding error, it s a gap large enough to change
Cryptography FundamentalsYour payment infrastructure likely relies on cryptographic methods that haven t been fully tested at the parameters you re using. This is more important now than it was six months ago. SQIsign , a pos
Cryptography FundamentalsYour Trusted Platform Module (TPM) is the cornerstone of your platform s cryptographic security. It safeguards your machine s keys, checks firmware integrity, and ensures your system remains untampere
Cryptography FundamentalsThe Challenge Your bank s encryption infrastructure faces a looming threat: quantum computers. These machines, though not yet fully realized, will make your current defenses obsolete once they arrive.
Cryptography FundamentalsYou ve seen the NIST announcements. You ve read the vendor whitepapers. Now someone in your organization is asking when you re planning to implement post-quantum cryptography to protect cardholder dat
Cryptography FundamentalsYou re protecting cardholder data with encryption schemes designed for classical computing threats. But quantum computers will eventually break RSA and elliptic curve cryptography, the foundation of m
Cryptography FundamentalsWhat Happened Researchers using circle-linear cryptanalysis on the CRAFT lightweight block cipher found a significant weakness: 2^108 keys, about one in every 37 trillion trillion possible keys, show
Cryptography FundamentalsYou re tasked with encrypting cardholder data. Your team reviews a research paper proposing a novel cipher variation, sees phrases like multidimensional affine transformation and rotating key matrices
