Table 3 Comparison of energy and computational, communication and storage costs
From: An anonymous authenticated key-agreement scheme for multi-server infrastructure
Protocols | Computational cost | Energy(mJ) | Communication cost(bits) | Storage cost(bits) |
|---|---|---|---|---|
Proposed | \(8T_{h}+7T_{h}+1T_{H}=0.0120 ms\) | 0.91 | 1920 | 1440 |
Liao and Wang [20] | \(9T_{h}+9T_{h}= 0.0117 ms\) | 0.98 | 2944 | 1024 |
Hsiang and Shih [21] | \(9T_{h}+12T_{h}= 0.0132 ms\) | 1.10 | 3296 | 1440 |
Lee et al. [22] | \(9T_{h}+10T_{h}= 0.0125 ms\) | 1.05 | 3296 | 1440 |
Chen and Lee [23] | \(12T_{h}+10T_{h}=.0146 ms\) | 1.24 | 3252 | 1440 |
Irshad et al. [25] | \(13T_{h}+13T_{h}+3T_{H}=0.0169 ms\) | 1.64 | 3872 | 1952 |
