Threshold ElGamal Encryption

Definition ∞ Threshold ElGamal encryption is a cryptographic scheme where a private key is divided among multiple parties, and a predetermined minimum number of these parties must cooperate to decrypt a ciphertext. This distributed key management approach enhances security by preventing any single entity from compromising the entire system. It provides robust fault tolerance.
Context ∞ In the digital asset domain, Threshold ElGamal encryption finds applications in secure multi-party computation and decentralized custody solutions. It can protect sensitive operations, such as signing transactions or managing shared secrets, by requiring collective action from multiple key holders. This technology contributes to building more resilient and trustworthy infrastructure for digital asset management and privacy-preserving protocols.
