Table 4 Comparison of SMCP and SAKA computation costs
From: SMCP: a Secure Mobile Crowdsensing Protocol for fog-based applications
| Â | SMCP | SAKA |
|---|---|---|
Fog Registration | \(T_{tls}+2T_{cert}+2T_{sed}\) | \(T_{kafc}+2T_{sed}\) |
Edge Registration | \(3T_{sed}+T_{tls}+T_{sig}+T_{cert}+2T_{ecm}\) | \(3T_{sed}+T_{kafc}+T_{sig}\) |
Edge-Fog | \(T_{x3dh}+4T_{sed}\) | \(T_{kaef}+4T_{sed}\) |
Fog-Cloud | \(T_{tls}+T_{sed}\) | \(T_{kafc}+T_{sed}\) |
Total cost | \(3T_{tls}+3T_{cert}+9T_{sed}+T_{sig}+T_{x3dh}\) | \(3T_{kafc}+9T_{sed}+T_{sig}+T_{kaef}\) |
