New Quantum Function Secret Sharing Protocol Introduced
/ 1 min read
🔗 New quantum function secret sharing scheme utilizes classical communication. Researchers have introduced a quantum function secret sharing protocol where a classical dealer distributes a secret quantum circuit to multiple quantum parties, who then compute and relay values back to the dealer using classical methods. This approach ensures that the shares reveal minimal information about the secret circuit while allowing the dealer to compute necessary outcomes. The protocol employs the Cayley path, a tool previously used in quantum supremacy claims. However, it has limitations: it is only secure against single adversaries, and the evaluation process requires exponential time relative to the number of gates involved.
