Combating Stealthy Thermal Covert Channel Attack With Its Thermal Signal Transmitted in Direct Sequence Spread Spectrum.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Computer-Aided Design of Integrated Circuits & Systems. Nov2022, Vol. 41 Issue 11, p4064-4075. 12p.

Abstract: Many-core systems are susceptible to attacks launched by thermal covert channel (TCC) attacks. Detection of TCC attacks often relies on the use of threshold-based approaches or variants, and a countermeasure to thwart the channel can be applied only af...

MIMO spread spectrum GFDM communication systems with index modulation.

Publication Type: Academic Journal

Source(s): International Journal of Communication Systems. 1/10/2023, Vol. 36 Issue 1, p1-18. 18p.

Abstract: Summary: In the fourth‐generation communication system (4G), orthogonal frequency division multiplexing (OFDM) is widely used. However, due to the cyclic prefix (CP) being added, the low spectrum efficiency and high out‐of‐band radiation (OOB) cause OF...

State Measurement and Control Technology of Unmanned Vehicle Based on High-Precision Positioning.

Publication Type: Academic Journal

Source(s): Mobile Information Systems. 10/31/2021, p1-9. 9p.

Abstract: For the unmanned vehicle system, the state measurement and control technology is one of the key links to realize the real unmanned vehicle. Based on RTK positioning technology and ultrashort wave spread spectrum communication technology, the key techno...

Expansion the signal spectrum by increasing the bandwidth through the channel.

Publication Type: Conference

Source(s): AIP Conference Proceedings. 2022, Vol. 2394 Issue 1, p1-8. 8p.

Abstract: Preventing interference is the main advantage of Spread Spectrum communication technique, this is crucial in different intelligent applications such as Narrowband Internet of Things (NB-IoT). The concept behind spread spectrum is using more bandwidth t...

Contention Minimization in Emerging SMART NoC via Direct and Indirect Routes.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Computers. Aug2022, Vol. 71 Issue 8, p1874-1888. 15p.

Abstract: SMART (Single-cycle Multi-hop Asynchronous Repeated Traversal) Network-on-Chip (NoC), a recently proposed dynamically reconfigurable NoC, enables single-cycle long-distance communication by building single-bypass paths directly between distant communic...

A Multipath Local Route Repair Scheme for Bidirectional Traffic in an Airborne Network of Multibeam FDD Nodes.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Aerospace & Electronic Systems. Aug2022, Vol. 58 Issue 4, p2983-2995. 13p.

Abstract: A directional airborne network consisting of nodes equipped with multibeam antennas is considered. These nodes use the frequency division duplex mode of communication. This allows formation of multiple routes between a pair of source and destination no...

Space--time receiver for spread spectrum communication systems with beam tracking.

Publication Type: Academic Journal

Source(s): IET Radar, Sonar & Navigation (Wiley-Blackwell). Jun2022, Vol. 16 Issue 6, p926-941. 16p.

Abstract: A method based on beam tracking in an underwater acoustic (UWA) time-varying channel was proposed to improve the performance of UWA spread spectrum communication systems using arrays. In the ocean, the acoustic signal reaches the receiver through vario...

Distributed Detection of Minimum Cuts in Wireless Multi-Hop Networks.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Computers. Apr2022, Vol. 71 Issue 4, p919-932. 14p.

Abstract: Communicating over multi-hop connections simplifies the establishment of wireless multi-hop networks but brings new challenges such as limited reliability, bottlenecks, and weak connections. The minimum cut of a graph is the smallest subset of edges wh...

Buffer State Based Relay Selection for Half-Duplex Buffer-Aided Serial Relaying Systems.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Communications. Jun2022, Vol. 70 Issue 6, p3668-3681. 14p.

Abstract: This work investigates multi-hop serial relaying half-duplex (HD) networks comprising one source, one destination and $K$ decode-and-forward (DF) relays. Buffer-aided (BA) relays are considered where finite size buffers are added to relays. For this se...

Coherent Detection of Synchronous Low-Rate DoS Attacks.

Publication Type: Academic Journal

Source(s): Security & Communication Networks. 3/23/2021, p1-14. 14p.

Abstract: Low-rate denial-of-service (LDoS) attacks are characterized by low average rate and periodicity. Under certain conditions, the high concealment of LDoS attacks enables them to transfer the attack stream to the network without being detected at all befo...
