EPEX: Matrix-free coefficient expansion for low-memory LWE experiments (opens in new tab)

EPEX — Embedded Procedural Expansion Engine — is an independent cryptographic engineering research artifact focused on one practical question: Can public LWE-style matrix coefficients be generated on demand, without persistently storing the matrix in embedded SRAM? EPEX explores a matrix-free expansion layer for Regev-style Learning With Errors (LWE) research on highly resource-constrained embedded targets. Instead of materializing a public matrix A as a static memory object, EPEX derives coe...
