Latest Patents

Wang holds a patent for a "Bootstrappable fully homomorphic attribute-based encryption method with unbounded circuit depth." This groundbreaking invention addresses the limitations of existing homomorphic attribute-based encryption (HABE) schemes, which are restricted to circuits with bounded depth or a limited number of inputs. The proposed fully homomorphic attribute-based encryption (FHABE) scheme enables computations of circuits with unbounded depth over cross-attribute ciphertexts. It features a lightweight ciphertext and eliminates reliance on the random oracle model. Furthermore, Wang's disclosure extends FHABE to a proxy re-encryption setting, introducing an attribute-based homomorphic proxy re-encryption scheme that allows efficient sharing of encrypted data. This scheme is notable for being the first lattice-based multi-hop attribute-based proxy re-encryption scheme with unbounded hops of re-encryptions.
