Homomorphic Encryption (HE) aims to perform computations on encrypted data. Still in research stage, a lot of HE schemes have been created but their comparison remains costly as execution exhibits prohibitive costs. PAnTHErS is a HE schemes modeler. Modeling with a common formalism allows the evaluation of input parameters variation impact on performances of a HE scheme execution i.e. on its execution time and its memory cost. However, choosing a values interval that makes sense during the exploration phase still requires high expertise. This may prevent the tool from a large adoption by novice users. In this paper, we remind functionalities of PAnTHErS and present an automated exploration method. This exploration method will offer designers a simplified access to PAnTHErS functionalities.
