Secure Data Access in Cloud Environments Using Quantum Cryptography
Cloud computing has made storing and accessing data easier but keeping it secure is a big challenge nowadays. Traditional methods of ensuring data may not be strong enough in the future when powerful quantum computers become available. To solve this problem, this study uses quantum cryptography to protect data in the cloud environment. Quantum Key Distribution (QKD) creates secure keys by sending information using quantum particles like photons. Specifically, we use the BB84 protocol, a simple …

Design high-confidence computers using trusted instructional set architecture and emulators
High-confidence computing relies on trusted instructional set architecture, sealed kernels, and secure operating systems. Cloud computing depends on trusted systems for virtualization tasks. Branch predictions and pipelines are essential in improving performance of a CPU/GPU. But Spectre and Meltdown make modern processors vulnerable to be exploited. Disabling the prediction and pipeline is definitely not a good solution. On the other hand, current software patches can only address non-essentia…

proud of little #footiMac. 2008 Core2 Duo iMac with 16GB RAM and a 1.5TB SSD
She's done excellent work in her space under the stairs. nearly a full year of uptime and chugging away doing Mastodon, Pixelfed (until just now), weewx Weather server, homebridge, streaming relay point, and general web server.
My next trick will be to see if I can move mastodon from using local storage for media to using cloud storage. I'm at about 70% usage now, so it's time.
Your old computers always have a purpose friends! Don't throw them away!
