In recent years, the number of companies are adopting cloud computing service for outsourcing is increasing. On the other hand, there are threats that are like falsification or leakage to data to be kept secret. Therefore, the technologies for managing encrypted data are the attractive topics in the cryptographic field. Among them, functional encryption which is constructed with pairing-based cryptography is closing to the practical stage because pairing operation is getting faster by the recent study of pairing. In addition, there are some pairing libraries which allow a user to introduce the pairing-based cryptography to their system. Nevertheless, they have some differences in several operations. In this paper, we reconstruct pairing-based homomorphic encryption by focusing on features of libraries and examine the performance evaluations of them.
