Pairing-based cryptography (PBC) provides us new cryptographicprotocols which cannot be constructed by the conventional public-key cryptosystems. In this research, we implemented ηT pairing and R-ate pairing on real-life computing environments such as mobilephones and GPGPU, and eventually we showed that PBC has become as efficient as RSA or elliptic curve cryptography on those devices. Moreover, we investigated the further development of ID-based encryption, and then we proposed an ID-based signcryption which is provably secure in the standard model.

基于配对的密码学（Pairing-based cryptography，PBC）为我们提供了传统公钥密码系统无法构造的新的密码协议。在这项研究中，我们在手机和GPGPU等现实计算环境中实现了ηT配对和R-ate配对，最终我们证明了PBC在这些设备上与RSA或椭圆曲线密码一样有效。此外，我们还研究了基于身份加密的进一步发展，并提出了一个在标准模型下可证明安全的基于身份的签密方案。
