This invention discloses a fully decentralized multi-committee attribute-based encryption method, belonging to the field of information security. It modifies the attribute organization into a committee composed of multiple nodes and designs the committee initialization, attribute key issuance and verification, and encryption and decryption algorithms. The committee uses the DKG protocol to generate public and private keys between nodes, while ensuring that the committee can tolerate 1 / 2 Byzantine nodes. An attribute key verification algorithm is designed to allow users to filter out invalid keys issued by Byzantine nodes. This invention applies X-ABE to implement the Decentralized Access Control Protocol (DACCS) in cloud storage scenarios, applying X-ABE to the stages of issuing user attribute keys and encrypting session keys to achieve encrypted data transmission. Combined with a sharded blockchain architecture, intra-shard consensus is used to ensure consistency among committee nodes during key issuance. User attribute information, ciphertext hash values, and other information are recorded on the blockchain.

This invention discloses a backdoor attack method, system, and medium based on multi-object semantic coexistence in text-to-image diffusion models. This method utilizes the perspective of multi-object semantic coexistence in text-to-image diffusion models to develop MOBA backdoor attack schemes. First, by constructing a trigger alignment dataset and optimizing backdoor implantation and semantic preservation in parallel, the attack success rate and visual concealment are effectively improved, reducing the impact of semantic corruption on attack effectiveness. Second, during model training, an attention-based decoupling backdoor enhancement mechanism is adopted. By decoupling the attention regions of different objects, the semantic integrity of the input prompt is maintained while the backdoor is activated and the attention distribution is reasonably adjusted to reduce the impact of generation bias on attack concealment. The method of this invention ensures both visual concealment and model performance under benign input while achieving efficient backdoor attacks.
