New Low-Memory Algebraic Attacks on LowMC in the Picnic Setting

Show other versions (1)

The security of the post-quantum signature scheme Picnic is highly related to the difficulty of recovering the secret key of LowMC from a single plaintext-ciphertext pair. Since Picnic is one of the alternate third-round candidates in NIST post-quantum cryptography standardization process, it has b...
