【摘要】 超奇异同源密码交换协议(SIDH)因其密钥长度短、且可以进一步对公钥进行压缩，使得SIDH协议在后量子密码领域更具竞争力。本文主要针对SIDH公钥压缩中双线性对计算这一“瓶颈”问题，在分析已有研究工作的实现过程基础上，采用预计算的方式提高公钥压缩中双线性对的计算速度。更多还原

【Abstract】 Supersingular isogeny Diffie-Hellman(SIDH) exchange protocol is a competitive candidate in the field of post quantum cryptography due to the short key length and the capability of further compressing the public key. To overcome the bottleneck of bilinear pairs calculation in SIDH public key compression, related available research works are reviewed in this paper, and pre-computation is adopted to improve the calculation speed of the bilinear pairs in public key compression.更多还原
