WebIND-CCA1 security is still an open problem (in contrast, group homomorphic schemes can be IND-CCA1-secure, e.g., CS-lite [14]). Some generic constructions of FHE schemes … WebCryptography forms the foundation of information security. In the last decade, many services affecting people's life and privacy have been put online and ensuring that sensitive information stays secure is very important. It is, therefore, necessary to understand why modern cryptography is considered secure, and exactly which security guarantees …
