TL;DR: In this article, the authors proposed a time slice synchronization technology, which is the basis of a multi-point synchronous communication, and belongs to the field of synchronous communications and is applicable to traffic control, traffic early warning and other wireless communication systems with large node change, high timeliness and multiple participating nodes.
Abstract: The invention provides a time slice synchronization technology, which is the basis of a multi-point synchronous communication, and belongs to the field of synchronous communications. In a general multi-point wireless communication, there are handshake waiting process, data collision conflict, low channel utilization and other time sequence synchronization problems. A multi-point synchronous communication system adopting the time slice synchronization technology has the advantages that handshake is not required, no conflict exits, the channel utilization is high and the support nodes are numerous and so on, so that the time slice synchronization technology provided by the invention is applicable to traffic control, traffic early warning and other wireless communication systems with large node change, high timeliness and multiple participating nodes.

TL;DR: In this paper , the authors quantify the size issue of post-quantum certificates in (D)TLS and QUIC and make the case for speeding up TLS handshakes by omitting the intermediate certificate authority certificates.
Abstract: Traditionally, the most data-heavy part of a (D)TLS handshake has been authentication which includes a handshake signature and digital certificates. Although most common (D)TLS usecases are not significantly affected, some constrained ones such as low bandwidth environments or delay sensitive applications can see drastic performance degradation due to big certificates or certificate chains. That has led the security community to seek options to alleviate the issue. Post-quantum signatures and keys, on the other hand, have been proven to noticeably slow down handshakes even for common Internet (D)TLS or QUIC applications due to the significantly higher amounts of post-quantum authentication data they include. In this work, we quantify the size issue of post-quantum certificates in (D)TLS and QUIC and make the case for speeding up (D)TLS and QUIC handshakes by omitting the intermediate certificate authority certificates in the handshake. We present how that can be achieved along with the usecases that will mostly benefit from such a mechanism. We offer quantitative analyses to show that this approach is relatively straightforward, backwards compatible and with little overhead introduced for caching the certificates. We also discuss caching mechanisms based on different optimization goals.

TL;DR: In this paper, the authors proposed a four-redundancy flight control computer syncing method for aircraft flight control systems. But the synchroscope is not considered in this paper.
Abstract: The invention relates to the technical field of aircraft flight control systems, in particular to a four-redundancy flight control computer syncing method, comprising: setting high logic for a synchroscope in a channel computer, and transmitting a high-logic sync signal to other channel computers through a remote channel; if a sync response signal is of high logic, determining the remote channel has successfully synced first handshake; otherwise defining the remote channel has step-out first handshake; setting low logic for the synchroscope; if the sync response signal is of low logic, determining the remote channel has successfully synced second handshake; otherwise defining the remote channel has step-out second handshake; when the remote channel has step-out first handshake or step-out second handshake, determining the remote channel is of transient step-out. The four-redundancy flight control computer syncing method can provide sampling, processing, balancing, deciding and the like simultaneously for redundancy sensor signals, and all computers use a common signal to finish calculation.

TL;DR: In this paper, the authors proposed an early four-way handshake method to reduce the time of the client side losing wireless connection during the access point transformation period time, when a wireless local area network device for supporting an APA is arranged between the access points which roams in the WLAN.
Abstract: The present invention relates to a method for connecting a wireless network device to a new access point in an early four-way handshake way. The method proposes a mechanism ''enhance pre-certification'', and the mechanism comprises two parts of an early four-way handshake part and an adjacent access point notification part. The present invention emphasizes the early four-way handshake part, the present invention aims at effectively reducing the time of the client side losing wireless connection during the access point transformation period time, when a wireless local area network device for supporting an APA is arranged between the access points which roams in the wireless local area network for supporting an APA. In the early four-way handshake method, the present invention mainly limits the negotiation of wireless local area network reconnection/connection to information exchange for only twice, and accomplishes the four-way handshake in the pre-certification period.

TL;DR: Lightweight minimal buffer router with FSM-based arbiter and priority assigner block is designed to enhance the speed, power, and area of asynchronous NOC architecture and achieves zero dynamic power consumption.
Abstract: Asynchronous NOCs are most prominent in present SOC designs, due to their low dynamic power consumption, modularity, heterogeneous nature, and robustness to the process variations. Though asynchronous designs are proved efficient over synchronous counterparts, they have some severe drawbacks when area and speed are considered, due to complex handshake control circuits which increase the static power loss. Quasidelay insensitive (QDI) class of asynchronous NOCs based on 2-phase encoding is proved beneficial for speed and throughput enhancement but with complex design. The work has introduced lightweight minimal buffer router based on LEDR encoding to design a low power, high speed with compact NOC architecture. Then, minimal buffer router with FSM-based arbiter and priority assigner block is designed to enhance the speed, power, and area. This proposed work achieves zero dynamic power consumption with a total power consumption of less than 0.082 W with a router latency of 0.8 ns.
