The private set intersection(PSI) protocol allows two parties holding a set of integers to compute the intersection of their sets without revealing any additional information to each other. The unbalanced PSI schemes consider a specific setting where a client holds a small set of the size n and a server holds a much larger set of the size m(n ■ m). The communication overhead of state-of-the-art balanced PSI schemes is O(m + n) and the unbalanced PSI schemes are O(nlogm). In this paper, we propose a novel secure unbalanced PSI protocol based on a hash proof system. The communication complexity of our protocol grows only linearly with the size of the small set. In other words, our protocol achieves communication overhead of O(n). We test the performance on a personal computer(PC) machine with a local area network(LAN)setting for the network. The experimental results demonstrate that the client only takes 2.01 s of online computation, 4.2. MB of round trip communication to intersect 1600 pieces of 32.bit integers with 2.0pieces of 32.bit integers with the security parameter λ = 512. Our protocol is efficient and can be applied to resource-constrained devices, such as cell phones.

Spiral tube heat exchangers have been widely used in phase change energy storage due to the compact structure and large heat transfer area. Therefore, this study numerically analyzes the effects of spiral tube diameter, number of rotations, and unsteady heat source on the melting process in conical spiral tube energy storage tanks using Fluent software. The results indicate that when the tube diameter is increased from 8 to 11 mm and the number of rotations is increased from 5 to 8, the melting time is extended by 15.74% and 17.83%, respectively. The energy storage capacity increases by 0.64% and 1.83%, respectively. The average energy storage rate decreases by 13.05% and 13.58%, respectively. Furthermore, the sinusoidal wave heat source with small heat source periods has little effect on the melting process, while large heat source periods can significantly accelerate the melting. And the influence of amplitudes on the thermal storage performance under large heat source periods is more *** the heat source period is increased from 2.to 160 min and the amplitude is increased from 5 to 2. K, the melting time is reduced by 2..50% and 17.2.%, respectively. The total energy storage capacity decreases by 6.36% and increases by 1.62.,respectively. The average energy storage rate increases by 2..03% and 2..74%, respectively. The study provides guidance for the performance optimization of spiral tube phase change systems.
