Study Notes
Image Compression and Physical Layer Security
- Image compression reduces file size without degrading image quality, allowing more images to be stored and reducing bandwidth when transmitted over the internet.
- There are two types of image compression: lossy and lossless.
- Lossy compression permanently removes less critical information, potentially distorting image quality if overly compressed.
- Lossy compression is irreversible and can lead to increased distortion with repeated application.
- Despite its limitations, lossy compression is valuable for web applications where some image degradation can be tolerated.
- Physical Layer Security (PLS) encompasses technologies like wiretap coding, secret key generation, authentication using physical unclonable functions, and others.
- Incorporating PLS in future wireless security standards requires further steps in terms of channel engineering and pre-processing.
- The practical deployment of PLS in 6G wireless networks faces key hurdles that need to be addressed.
- Research directions and possible solutions are presented in the context of incorporating PLS into 6G security.
- Key approaches to authentication in the context of PLS include physical unclonable functions, localization-based authentication, and RF fingerprinting.
- Challenges such as secure key distribution, user and device authentication, and resilience to physical layer denial of service attacks have been identified in the context of PLS.
- The paper reflects on the growing discussion in the community and presents a vision for context-aware 6G security that incorporates PLS.
