不完美量子封印的可读性与安全性关系研究

Relationship between readability and security of imperfect quantum seal

研究了一个不完美量子封印协议。分析了不完美量子封印可被读取者(Bob)自行读取封印信息b的几率即可读性α与信息被读取封印遭破坏后封印者(Alice)能检测出来的几率即安全性β之间的关系。结果表明:β小于等于1/2,α与β之和小于等于9/8。最后通过一个具体实例来验证该关系式。

An imperfect quantum sealing protocol was studied,and an inequality based on the readabilityα which Bob can measure the information and security β which Alice can detect the information to be measured was provided.The results show that,when the security β is not greater than 1/2,the sum of readability α and security β is not greater than 9/8.Finally,the inequality was proved through a specific example.
