When evaluating Homomorphic Encryption (HE) schemes, only one set of input parameters is usually considered. Evaluation reports HE scheme time execution and memory consumption because these are the main challenges of HE. PAnTHErS enables to evaluate HE schemes without executing the scheme, hence with an affordable processing time. Results are provided in terms of computational complexity and memory cost. This allows to evaluate a scheme for numerous sets of input parameters. In this paper, PAnTHErS is improved by a calibration phase, and four HE schemes based on Ring-LWE are analyzed and compared using the proposed tool.
