Security of Low Computing Power Devices: A Survey of Requirements, Challenges & Possible Solutions

Security has been a primary concern in almost all areas of computing and for the devices that are low on computing power it becomes more important. In this paper, a new class of computing device termed as Low Computing Power Device (LCPD) has been defined conceptually. The paper brings out common attributes, security requirements and security challenges of all kinds of low computing power devices in one place so that common security solutions for these can be designed and implemented rather than doing this for each individual device type. A survey of existing recent security solutions for different LCPDs hasve been presented here. This paper has also provided possible security solutions for LCPDs which include identification of countermeasures against different threats and attacks on these devices, and choosing appropriate cryptographic mechanism for implementing the countermeasures efficiently.
