Bilinear Pairings: Modern Privacy-Preserving Cryptography
If you’ve spent any time reading about modern cryptography — especially BBS Signatures, attribute-based credentials, or identity-based encryption — you’ve probably encountered the phrase bilinear pairing.

Elliptic Curve Cryptography: The Tiny Keys That Protect the Internet
If you’ve spent any time reading about modern cryptography, you’ve probably encountered the phrase Elliptic Curve Cryptography (ECC). It sounds less like a security technology and more like an elective mathematics course that everyone regrets taking — I’ve been in several of those.

Selective Disclosure: The Math
Selective Disclosure is fundamentally a mathematical concept. The protocols (SD-JWT VC, BBS-2023, AnonCreds, Idemix, U-Prove, etc.) are really just engineering built on top of several branches of mathematics.
