Then, if some (up to a threshold f out of n) of these parties are corrupted, the key secrecy remains uncompromised. Using a “secret sharing” mechanism, the secret key is split across multiple "parties". Legend: 2KE = pair-wise key- establishment KC = Key confirmation KD = Key derivation Keygen = key- generation PKE = Public- key encryption PRF = pseudo random function (family) PRP = pseudo random permutation (family) QR = quantum resistant TF = threshold friendly ZKPoK = Zero- knowledge proof of knowledge. Low-round multi-party key- agreement (KA) Succinct & verifiable-deterministic signatures Subcategories and examples of primitives in Cat2 Subcategory: Type Legend: 2KA = pair-wise key- agreement 2KE = pair-wise key- establishment AES = Advanced Encryption Standard CDH = Cofactor Diffie- Hellman ECC = Elliptic- curve cryptography ECDSA = Elliptic- curve Digital Signature Algorithm EdDSA = Edwards-Curve Digital Signature Algorithm KC = Key confirmation KDM = Key derivation mechanism Keygen = Key- generation MQV = Menezes- Qu- Vanstone PKE = Public- key encryption RSA = Rivest- Shamir- Adleman RSADSA = RSA digital signature algorithm.
