基于量子容错构造的量子全同态加密方案

Quantum fully homomorphic encryption scheme based on quantum fault-tolerant construction

Min Liang, Li Yang

摘要:

全同态加密是一种加密方案,它可以在不访问加密数据的情况下对加密数据进行任意计算。基于量子容错构造,提出了一种量子版本的全同态加密方案。构造了两种方案。第一种是对称方案,密钥是量子CSS码。在该方案中,当服务器对加密后的明文进行量子计算时,客户端需要提供一些辅助的量子态。第二种方案是非对称方案,它包含客户端和服务器之间的周期性交互。

英文摘要:

Fully homomorphic encryption is a kind of encryption scheme, which enables arbitrary computation on encrypted data without accessing the data. We present the quantum version of fully homomorphic encryption scheme, which is constructed based on quantum fault-tolerant construction. Two schemes are constructed. The first is a symmetric scheme, and the secret key is the quantum CSS code. In the scheme, when Server performs quantum computation on the encrypted plaintext, some ancillary quantum states should be provided by Client. The second is an asymmetric scheme, which contains the periodical interaction between Client and Server.
