Puncturable fully homomorphic encryption based on Bloom filter

Fully Homomorphic Encryption (FHE) empowers secure computation over encrypted data, offering a crucial solution for privacy-preserving applications in cloud computing. However, the security of FHE is contingent upon robust key management practices. This article introduces a novel FHE scheme that integrates a robust key revocation mechanism. By incorporating key revocation, our scheme ensures forward secrecy, guaranteeing that the confidentiality of previously encrypted data remains intact even if the secret key is subsequently compromised.
