Current analysis on payment security, fraud prevention, AML/KYC, and PCI DSS compliance.
Cryptography FundamentalsWhat Changed Two witness encryption constructions, the affine determinant program (ADP) and its arithmetic extension (AADP), have been compromised. Attacks can now recover encrypted messages directly
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 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 FundamentalsWhat Happened A research team has developed a fully homomorphic encryption (FHE) scheme with chosen-ciphertext attack (CCA) security, based solely on the learning with errors (LWE) assumption in the s

Cryptography FundamentalsMany believe that once a payment card expires, it s useless. Chip-and-PIN technology and cryptographic validation supposedly render an expired card incapable of completing transactions. So, why bother
Cryptography FundamentalsYour compliance team manages cardholder data across multiple processors, each needing access under different conditions. Traditional encryption forces a choice: encrypt separately for each party (lead
Cryptography FundamentalsAre you still using the same encryption algorithms you chose five years ago? Your compliance documentation might list approved cryptographic standards, and your quarterly reviews confirm you re still
