NIST has initiated the deprecation of RSA and ECDSA by 2030, signaling a shift in cryptographic standards. Is Falcon a viable replacement for ECDSA? Falcon, a lattice-based signature scheme, stands out for its low communication overhead, boasting significantly smaller public key and signature sizes compared to many alternatives. This efficiency is crucial for applications where bandwidth is limited, such as cryptocurrencies, IoT devices and mobile communications. Or is further research and st...
