Webb22 mars 2024 · To simplify the certificate management, Naccache introduced a notion of identity-based fully homomorphic encryption (IBFHE), where there is no user-specific key that the evaluator must use. In particular, in an IBFHE scheme, data encrypted under a single identity can perform homomorphic operations by any evaluator with only public … WebbAll IBFHE constructions mentioned above use the single identity based setting in the sense that homomorphic addition and multiplication can be done on the ciphertexts en-crypted under the same identity. Clear and McGoldrick Clear and McGoldrick (2015) extends this to multi-identity setting and obtained the first leveled multi-identity IBFHE
WebbEncryption (IBFHE) scheme and the rst leveled Attribute-Based Fully Homomorphic Encryption (ABFHE) scheme from the Learning with Errors (LWE) problem. Clear and McGoldrick [7] extended the former to achieve \multi-identity" leveled IBFHE where evaluation can be performed on ciphertexts associated with di erent identities. Webb4 apr. 2024 · Identity-based fully homomorphic encryption (IBFHE) provided a fundamental solution to the problem of huge public key size that exposed in fully homomorphic encryption (FHE) schemes, thus it is significant to make FHE become more practical. In recent years, the construction of IBFHE schemes were mainly based on lattices due to …

Finally, we characterize presently-known leveled IBFHE schemes with a view to developing a ``compiler'' from a leveled IBFHE scheme to a bootstrappable IBFHE scheme, and sufficient conditions are identified.
