Common use of Comparisons Clause in Contracts

Comparisons. 𝜂2 = 𝑞 = 7𝑛 = 14.3% We have selected three different types of key negotiation protocols for comparison with our protocol, and the results are shown in Table 2: Table 2 Comparison among related protocols Protocols η (%)1 η (%)2 Semi- quantum Controlling party Ref. [26] 6.7 8.3 Yes Yes Ref. [22] 8.3 11.1 No Yes Ref. [25] 10 12.5 Yes No our protocol 12.5 14.3 Yes Yes According to the data in the table, we can see that the efficiency of our protocol is the highest when there is a third party and semi-quantum agreement function is realized. Under the condition of three- particle entangled resources, our protocol does not require the third party to distribute the key with the classical party in advance, which is much better than the protocol [22] in terms of scheme steps and quantum resources. In addition, our proposed protocol simplifies the work of the quantum cloud, where the cloud Trent is only responsible for generating and distributing quantum resources. All measurements are entrusted to the Quantum Center. To sum up, our protocol simplifies steps on the premise of ensuring security, and maintains efficiency at a relatively high level, which has certain practical application value.
