- In 3.2.2 data collection, the Average function in the construction of proposed scheme the notation f is not used in the subsequent construction, please explain the function of this notation in detail
- $TD_{ij}$ is used in the text but $TD_i$ in the notation table is not mentioned, and the expression of s, s' notation mentioned in construction is not clear (is it under the same Edge?)
- This paper doesn't mention the initialization of $k^t_{ij}$.
- Security analysis is informal.
- This paper claim to use lightweight cryptography, but it intend to use differential privacy in the extensions section which will make your system less lightweight.
