Threshold cryptosystem
TYPE OF CRYPTOSYSTEM WHICH REQUIRES SEVERAL PARTIES (MORE THAN SOME THRESHOLD NUMBER) TO COOPERATE IN THE DECRYPTION PROTOCOL
Threshold encryption; Threshold cryptography
A threshold cryptosystem, the basis for the field of threshold cryptography, is a cryptosystem that protects information by encrypting it and distributing it among a cluster of fault-tolerant computers. The message is encrypted using a public key, and the corresponding private key is shared among the participating parties.
