Secret key management remains demanding regardless of classical or post-quantum cryptographic algorithms. To help with this, threshold cryptography splits the secret key into multiple shares that can be stored and secured separately. Thus, even a complete device compromise does not allow the attacker to decrypt the user's private data or issue digital signatures on its behalf. Threshold variants of classical signature schemes, such as Schnorr or ECDSA, are actively researched and finding their way into practice, for example, in Bitcoin. To help users and developers discover threshold cryptography, the researchers and students from the Centre for Research on Cryptography and Security (CRoCS) from Masaryk University have developed MeeSign - an open-source platform for demonstrating threshold cryptography protocols.
