Abstract (in Japanese) (See Japanese page) 
(in English) Aggregator Oblivious Encryption (AOE) was proposed by Shi et al. in NDSS 2011. AOE with public verifiability was also proposed by Leontiadis et al. in CANS 2015 and Emura in ACISP 2017 respectively. This paper gives implementation of Leontiadis et al. and Emura schemes and evaluates their performances. We employed Raspberry-Pi as a power-constrained device such as a smart meter, and also set the message space by considering the capability of a commercially available smart meter. Due to the reduction loss of these schemes and the evaluation by Menezes et al. in Mycrypt 2016, we employed Barret-Naehrig curves with 1031 bits order for the Leotiadis et al. scheme and 383 bits order for the Emura scheme to achieve 112-bit security. In addition, we applied the condition given by Benhamouda et al. in ACM TISSEC 2016 (length for the time period and the number of users are $2^{20}$). Consequently, we demonstrate that the running time of data encryption, data aggregation, and verification in the Emura scheme are approximately 25%, 36%, and 11% respectively compared to those of the Leontiadis et al. scheme.
