lib25519 for RISC-V
Timing-attack resistant, high performance microlibrary for ECC 25519
Modern network protocols rely on elliptic-curve cryptography (ECC) to protect communication against espionage and sabotage. ECC is faster than RSA, but it still consumes many CPU cycles, especially when an attacker floods a server's CPU with requests. lib25519 is a software library for the Curve25519 elliptic curve, including the X25519 encryption system and the Ed25519 signature system. Curve25519 is the fastest curve in TLS 1.3, and the only curve in Wireguard, Signal, and many other applications. So far lib25519 has exploited the features of Intel and ARM CPUs to provide top speeds for those CPUs, while meeting the security constraint of not leaking secret information through timing. This project will extend lib25519 to target 64-bit CPUs of RISC-V and provide efficient 64-bit implementations for the architecture.
