The set of parameters suggested by Falcon imply a signature size of 666 bytes and a public key size of 897 bytes for the NIST security level 1 (security comparable to breaking AES -128 bits).

Using the reference implementation on a common desktop computer (Intel® Core® i5-8259U at 2.3 GHz, TurboBoost disabled), Falcon achieves the following performance: Sizes (key generation RAM …

Large Stack Usage: Implementations identified as having such may cause failures when running in threads or in constrained environments.

Falcon uses NTRU as a asymmetric encryption and has been benchmarked as twice as fast as RSA to encrypt, and three times faster to decrypt. NTRU is the public key method which is not based on the …

new private key storage format has been designed; private keys now fit in 1281 bytes (Falcon-512) or 2305 bytes (Falcon-1024). Public key encodings and sizes are unchanged.

Algorand uses a random seed of \ ( 48 \) bytes for FALCON key generation.

Falcon (Digital Signatures) Falcon is a post-quantum digital signature scheme based on the NTRU lattice structure, offering compact signatures and fast verification.

Jul 11, 2025 · The set of parameters suggested by Falcon imply a signature size of 666 bytes and a public key size of 897 bytes for the NIST security level 1 (security comparable to breaking AES -128 …

Oct 28, 2020 · The inputs and outputs of the three components are the message, signature, public key, and secret key. We express these inputs and outputs as fixed size arrays.

With Falcon-512 (which has an equivalent security to RSA-2048), we generate a public key of 897 bytes, and a signature size of 666 bytes, while FALCON-1024 gives a public key of 1,793 bytes and a …
