Blind quantum computation allows a client who does not have enough resources or technologies to achieve on remote server such that the client's input, output, and algorithm remain unknown server. Up now, single- double-server blind been considered. In this work, we propose triple-server protocol where can delegate three servers by use of entanglement swapping. Furthermore, communicate with each other is almost classical since one require any computational power, memory, ability prepare...

Semiquantum key distribution (SQKD) allows two parties to share a common string when one of them is quantum and the other has rather limited capability. Almost all existing SQKD protocols have been proved be robust in theory, namely that if an eavesdropper tries gain information, he will inevitably induce some detectable errors. However, ideal devices do not exist reality their imperfection may result side-channel attacks, which can used by adversary get information on secret string. In this...

Recently, multiparty quantum key agreement (MQKA) protocols have gained increasing attention. Several MQKA in the traveling mode been proposed for higher generation rates, which, however, are vulnerable to a collusive attack presented by Liu.

Because system, our has huge advantages scalability and can be realized...

In the harsh environment, wireless sensor networks can suffer from a significant damage that causes many nodes/links to fail simultaneously and network get splitted into multiple disjoint partitions. such case, linking separated partitions by placing least number of relay nodes obstacle-avoiding re-establish strongly connected topology is necessary maintain functional operations network. However, problem finding minimum count position NP-hard hence heuristics methods are preferred. this...

We experimentally demonstrate a high-speed phosphorescent white light emitting diode (LED) visible communication (VLC) system without utilizing an optical blue filter. Here, the response is equalized by using proposed analog equalizers. The 3 dB bandwidth of VLC link could be extended from to 132 MHz, which allows 330 Mbit/s non-return-to-zero on–off keying (NRZ-OOK) data transmission with bit error ratio (BER) 7.2×10 10 and 672 64-quadrature amplitude modulation (64-QAM) BER 3.2×10 3. These...

Wireless sensor networks(WSNs) have many applications in recent years, especially some harsh environment, such as battlefield reconnaissance. WSNs may suffer from a large scale damage which causes nodes to fail and the network get partitioned into disjoint segments. So order avoid negative effects on application, restoring connectivity is crucial case.

Abstract Fairness is an important standard needed to be considered in a secure quantum key agreement (QKA) protocol. However, it found that most of the protocols travelling model are not fair, i.e., some dishonest participants can collaborate predetermine final without being detected. Thus, how construct fair and protocol has obtained much attention. In this paper, new multiparty QKA resist collusive attack proposed. More specifically, we show client-server scenario, possible for clients...

Mobile sensor networks (MSNs) have many applications in recent years, especially some harsh environment, such as coastal and border protection, search-and-rescue, battlefield reconnaissance so on.
