FISCO BCOS采用的是paillier加密算法,支持加法同态。paillier加解密兼容主流的RSA公钥加密算法,接入门槛低。同时paillier作为一种轻量级的同态加密算法,计算开销小易被业务系统接受。因此经过功能性和可用性的权衡,最终选定了paillier算法。

FISCO BCOS uses the paillier encryption algorithm which supports addition homomorphism. Paillier is compatible with mainstream RSA public key encryption algorithms, and the use costs is low. At the same time, paillier, as a lightweight homomorphic encryption algorithm, has low calculation overhead and is easily accepted by business systems. Therefore, after balancing the trade-off between functionality and usability, the paillier algorithm was finally selected.
