加密信号之间的安全相似性验证

Secure Similarity Verification Between Encrypted Signals
摘要：
A method for verifying a similarity between a first signal and a second signal is described. The first and the second signals are encrypted homomorphically using a key. First, we acquire a set of error patterns determined by a similarity constraint. Then, each error pattern is homomorphically encrypted using the key and presented to a verifier in the setup phase. The verifier declares the first signal similar to the second signal, if any error pattern in the set of error patterns satisfies a homomorphic relationship between the first encrypted signal and the second encrypted signal.

描述了用于验证第一信号和第二信号之间的相似性的方法。 第一和第二信号使用密钥同态加密。 首先，我们获取由相似性约束确定的一组错误模式。 然后，使用密钥对每个错误模式进行同态加密，并在设置阶段提供给验证者。 验证者声明类似于第二信号的第一信号，如果错误模式集合中的任何错误模式满足第一加密信号和第二加密信号之间的同态关系。
