Security Enhancement of an Authentication Scheme Based on DAC and Intel SGX in WSNs Document Type : Research Article Authors: Maryam Rajabzadeh Asaar ،Mustafa Isam Ahmed Al-Baghdadi https://lnkd.in/d9WBgqwJ Abstract Designing authentication techniques suitable for wireless sensor networks (WSNs) with their dedicated consideration is critical due to the nature of public channel. In 2022, Liu et al. presented an authentication protocol which employs dynamic authentication credentials (DACs) and Intel software guard extensions (SGX) to guarantee security in WSNs, and it was shown that it is secure by formal and informal security analysis. In this paper, we show that it is not secure against desynchronization attack and offline guessing attack for long-term random numbers of users. In addition, it suffers from the known session-specific temporary information attack. Then, to address these vulnerabilities an improved authentication scheme using DAC and Intel SGX will be presented. It is shown that not only it is secure against aforementioned attacks with employing formal and informal analysis, but also it has a reasonable communication and computation overhead. It should be highlighted that the communication and computation overheads of our proposal are increased negligibly, but it provides more security features compared to the baseline protocol.

**"Unlocking the Power of Radio and Wireless Signals with HackRF One** As a cybersecurity enthusiast and penetration tester, I'm always excited to explore the capabilities of innovative tools like the HackRF One. Recently, I had the opportunity to experiment with this powerful device, and I was impressed by its ability to capture, store, and emulate radio and wireless signals. Using the HackRF One, I was able to intercept and record a wireless bell signal, which I could then store and replay at will. This capability has significant implications for security testing and research, as it allows us to analyze and understand the underlying protocols and vulnerabilities of wireless systems. The HackRF One's versatility and customizability make it an invaluable tool for anyone working in the fields of cybersecurity, radio frequency (RF) engineering, or signal processing. Its ability to transmit and receive signals across a wide range of frequencies (from 10 MHz to 6 GHz) makes it an ideal platform for experimenting with various wireless protocols and technologies. Some potential applications of the HackRF One include: * **Wireless penetration testing**: Use the HackRF One to simulate and analyze wireless attacks, such as replay attacks or jamming. * **RF research and development**: Leverage the HackRF One's capabilities to design and test new wireless protocols or systems. * **Signal analysis and processing**: Utilize the HackRF One to capture and analyze RF signals, and develop custom signal processing algorithms. If you're interested in learning more about the HackRF One and its capabilities, I'd be happy to share more information and resources. Let's connect and explore the possibilities of RF and wireless signal processing together! #HackRF #WirelessSecurity #RadioFrequency #SignalProcessing #Cybersecurity #PenetrationTesting #RFResearch #WirelessProtocols"

TIL: Your computer's hardware is secretly fighting cybercrime **TL;DR:** Modern CPUs have built-in security features, memory design affects vulnerabilities, and even power consumption can leak data. Hardware is the unsung hero of cybersecurity. --- Fellow tech enthusiasts, prepare to have your minds blown! 🤯 I just discovered something wild in my computer architecture studies: our hardware is secretly battling cyber threats! Here's the scoop: 1. **CPUs are undercover security guards** * Not just number crunchers anymore * Features like ARM's TrustZone and Intel's SGX create secure zones in the chip * It's like having a bouncer for your data! 2. **Memory: The double agent of computer security** * How computers handle memory can be a strength AND a weakness * Ever heard of cache timing attacks or row hammer vulnerabilities? Yeah, me neither until now 3. **Your computer is whispering secrets** * Hackers can potentially steal data by listening to power consumption or electromagnetic emissions * It's like eavesdropping, but for machines. Mind-boggling, right? The big revelation: Cybersecurity isn't just about fancy software. It's baked into the silicon and circuits of our devices. Now I'm wondering: How will quantum computing shake all this up? Are we looking at a whole new level of hardware security? What do you think? Is hardware the unsung hero of cybersecurity? Let's geek out in the comments! **Edit:** Wow, this blew up! Thanks for all the insightful comments. Looks like a lot of us are fascinated by the hidden world of hardware security! #Cybersecurity #ComputerHardware #TechTrends #InfoSec #CPUSecurity #QuantumComputing #DataProtection #TechInnovation #ComputerArchitecture #HardwareSecurity #CyberThreats #FutureOfTech #TechTalk #STEM

Let's talk about the evolution of rootkits! Modern rootkits are more sophisticated and harder to detect. Here's a quick breakdown. # Firmware and Hardware-Level Rootkits: Firmware Rootkits: These hide in device firmware (like BIOS or UEFI) and are tough to remove. Microcode Attacks: Target CPU microcode to introduce malware. FPGA and ASIC Compromises: Attacks on custom hardware (like FPGA or ASICs) are rare but growing, especially in critical sectors. # Kernel and Bootkits: Kernel-Level Rootkits: They manipulate OS kernels to stay hidden and avoid detection. Bootkits: Infect the boot process to control the system before the OS loads, even bypassing encryption. Advanced Stealth Techniques: Hypervisor Rootkits (Blue Pill): Use virtualization to create undetectable hypervisors. Memory Resident Rootkits: These live in memory and avoid traditional antivirus detection. Modern Threat Vectors: Supply Chain Attacks: Rootkits can come through compromised supply chains and updates. Cloud & Virtualization: Exploit weaknesses in cloud services and virtualization platforms. Detection and Mitigation: Behavioral Analysis & Machine Learning: Use AI to spot rootkit activity. Hardware Security: Intel TXT and AMD Secure Processor help defend at the hardware level. Firmware Checks: TPM and secure boot processes keep firmware safe. #AI #SupplyChain #CloudSecurity #Hypervisor #StealthTech #KernelSecurity #Bootkits #FPGA #ASIC #HardwareHacks #Firmware #HardwareSecurityCyberSecurity #Rootkits #InfoSec

Security is no longer an afterthought but a fundamental aspect of electronic design. Hackers, ranging from hobbyists to nation-states, continually target vulnerabilities in our electronic devices. Currently, around 60% of chips feature some form of built-in security, and this number is rising. The decision on the level of security is complex, involving performance, cost, and regulatory compliance considerations or tradeoffs. The future of security in electronics lies in increasing standardization and possibly leveraging technologies like fully homomorphic encryption. #cryptoprocessor #systemonchip #chipsecurity #cybersecurity #softwaresecurity #encryption #semiconductordesign
