Homomorphic encryption is considered a major privacy-preserving technique, especially in, but not limited to, machine learning (Aono et al.2017). Even though the need for privacy-preserving techniques has been stressed by many in the context of ABAC (i.e., Xu et al. (2020); Park and Chun...

Homomorphic Encryption (HE) represents a revolutionary stride in the field of cryptography. This technique allows for computations to be performed on encrypted data without needing to decrypt it first, thereby maintaining data privacy throughout the process. The potential applications of HE are vast an...

Among them,homomorphic encryptionis obviously related to cryptography. At present, the open source projects of homomorphic encryption algorithms have their own advantages and disadvantages, and users are more complicated to use them. As a basic cryptographic library, BabaSSL should provide a set of eas...
