Bozhko and Kutsenok (@reclaimprotocol) propose zkPoPE, a transport-agnostic zkTLS security model, and Reclaim Protocol, which UC-realizes it and attests 1200kB in 7.28s.Bozhko与 @reclaimprotocol 的Kutsenok在论文中提出应用层zkTLS安全模型zkPoPE,并给出UC实现Reclaim Protocol,可证明真实协议执行,支持1200kB响应证明。Bozhko氏と @reclaimprotocol のKutsenok氏は論文で、応用層向けzkTLS安全モデルzkPoPEを提案し、これをUC実現するReclaim Protocolを提示した。実プロトコル実行を証明し、1200kB応答の証明も可能とする。
NotesNotes要点
First transport-agnostic security model for zkTLS, defined at the application layer.
zkPoPE requires proof that private input and received reply satisfy a property, and that the reply came from a real execution, not fabrication.
zkPoPE is formalized as UC ideal functionality F_zkpope.
Reclaim Protocol UC-realizes F_zkpope under a deployment-aligned trust model and underlies a production system.
It introduces Distributed-AEAD, a new three-party authenticated-encryption primitive.
On a lower-mid-range phone, it attests 1200kB in 7.28s, two orders beyond prior zkTLS benchmarks.
How does zkPoPE go beyond NIZK?zkPoPE比NIZK强在哪?zkPoPEはNIZKをどう超えるか?
It also requires the reply to come from a real execution, not merely a satisfying input-reply pair.它额外要求回复来自真实协议执行,而非仅存在满足属性的一对输入与回复。返答が実際のプロトコル実行に由来することを要求し、単なる入力・返答の充足ペアとは異なる。
What UC guarantee does Reclaim provide?Reclaim提供怎样的UC保证?ReclaimはどのUC保証を提供するか?
Under a deployment-aligned trust model, Reclaim UC-realizes F_zkpope, providing composable security guarantees.在部署对齐信任模型下,Reclaim在UC框架中实现F_zkpope,提供可组合安全保证。展開整合型信頼モデルの下で、ReclaimはF_zkpopeをUC実現し、合成可能な安全保証を与える。
What scalability does Reclaim demonstrate?Reclaim的规模测试结果如何?Reclaimの拡張性は?
On a lower-mid-range phone, it attests a 1200kB response in 7.28s, two orders beyond previous zkTLS benchmarks.中低端手机7.28秒证明1200kB响应,比此前zkTLS基准高两个数量级。中低端スマホで1200kB応答を7.28秒で証明し、従来zkTLSベンチの2桁上を行く。
