Editing Chapter 6: Edge Security and Privacy (section)

==='''Side-Channel Attacks'''===

''Side-Channel Attacks'' happen when an attacker constantly obtains certain ''side-channel information'', like using public information that is not privately-sensitive for a user, from the target edge computing infrastructure and then feeds it into specific algorithms or machine learning models that outputs the desired sensitive information. There are three kinds of Side-Channel attacks: attacks exploiting communication channels, attacks exploiting power consumption, and attacks exploiting smartphone-based channels.

*''Attacks exploiting communication channels'' are when an attacker can use a malicious node, that doesn't have to be an edge server or device, in order to exploit communication channels and uses the node to continuously sniff the network traces and wishes to extract sensitive information out of them. 

*''Attacks exploiting power consumption'' are when attackers use smart meters and oscilloscopes in order to measure the power consumption of a system since it carries information related to either the device that consumes the energy as different devices have different power. 

*''Attacks exploiting smartphone-based channels'' are when attackers exploit vulnerabilities using /proc and smartphone embedded sensors due to how sensors can leak information and send malware to the user that they can install but disguised as something important and attack /proc.
