    As the cryptographic community turns its focus toward post-quantum cryptography, the demand for classical cryptographic schemes such as Elliptic Curve Cryptography (ECC) remains high. In this work, we present an optimized implementation of the Edwards Curve Digital Signature Algorithm (EdDSA) operations Keygen, Sign, and Verify using the Ed25519 parameter on the ARM Cortex-M4 using optimized assembly code. We discuss the optimization of field and group arithmetic to produce high-throughput cryptographic primitives. Then, we present the first SCA-resistant implementation of the Signed Comb method, and Test Vector Leakage Assessment (TVLA) measurements. Our fastest implementation performs Ed25519 Keygen in 200,000 cycles, Sign in 240,000 cycles, and Verify in 720,000 cycles on the ARM Cortex-M4.
