Survey on secure identity authentication mechanisms for fog-based internet of things (IoT)‎ applications

الملخص EN

Fog computing enabled scalability and flexibility features to the internet of things (IoT) since it helped in reducing the communication traffic and enhanced the communication response time between the devices and the cloud.

however, fog computing inherited vulnerabilities for many attacks including Sybil attacks, impersonating attacks, and even denial of service attacks.

for that reason, it became essential to provide security to the fog layer.

thus, implementing a secure authentication scheme as the first security line for a system is a necessity.

in this paper, we are reviewing some recent approaches that have been developed for secure authentication in fog computing and presenting a comparison between them considering different criteria such as user identification’s methodology, the used cryptographic algorithm, and the mobility support.
