OS の脆弱性が報告されており，秘匿性の高いデータを処理するプログラムの実行環境として，OS の信頼性は不確実なものとなっている．これに対して信頼実行環境の一つである Intel SGX では，Enclave と呼ばれる隔離環境の中で重要なデータを扱うプログラムを実行することで，OS に対する悪性の攻撃などからデータを保護する．しかしながら，アプリケーションのホストと Enclave の間で授受可能なデータ構造は現状では配列のような単純なものに限られており，ポインタを含むデータ構造を扱う場合は高コストなデータのシリアライズ処理を要する．本稿では，ファットポインタとメモリプールを用いることで，ポインタを含むデータ構造について柔軟かつ効率的なデータ授受を可能とする手法を提案する．本手法を用いて vector と list の授受を行ったところ，シリアライズを行った場合と比較してそれぞれ最大で 18.52 倍，19.64
