论文摘要
量子加密协议中安全性的金标准是信息理论安全性。信息理论的安全性肯定是防前的,因为它没有对任何计算问题的硬度做出任何假设,并且仅依赖于量子力学的基本定律。在这里,我们通过信息理论安全性重新访问了一个限制键量量子同态加密协议。我们解释了如何将该协议与具有误差校正编码为同态的量子误差校正整合。此功能使客户端和服务器都可以在不使用加密排列键的情况下应用编码和解码步骤进行量子误差校正。
The gold-standard for security in quantum cryptographic protocols is information-theoretic security. Information-theoretic security is surely future-proof, because it makes no assumptions on the hardness of any computational problems and relies only on the fundamental laws of quantum mechanics. Here, we revisit a permutational-key quantum homomorphic encryption protocol with information-theoretic security. We explain how to integrate this protocol with quantum error correction that has the error correction encoding as a homomorphism. This feature enables both client and server to apply the encoding and decoding step for the quantum error correction, without use of the encrypting permutation-key.
