APPARATUS AND METHOD WITH HOMOMORPHIC ENCRYPTION OPERATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240340158 titled 'APPARATUS AND METHOD WITH HOMOMORPHIC ENCRYPTION OPERATION
The abstract describes a homomorphic encryption operation method performed by a computing device with processing and storage hardware.
- Receiving and storing a ciphertext with modules in the storage hardware.
- Receiving and storing an operation key with a relinearization key corresponding to the ciphertext.
- Performing a homomorphic encryption operation on the ciphertext based on the dimension and number of modules.
Potential Applications: - Secure data transmission - Privacy-preserving data analysis - Secure cloud computing
Problems Solved: - Protecting sensitive data during computation - Ensuring data privacy in outsourced computations
Benefits: - Enhanced data security - Facilitates secure data sharing - Enables privacy-preserving data analysis
Commercial Applications: Homomorphic encryption technology can be utilized in industries such as finance, healthcare, and government for secure data processing and analysis.
Questions about Homomorphic Encryption: 1. How does homomorphic encryption differ from traditional encryption methods? Homomorphic encryption allows computations to be performed on encrypted data without decrypting it first, unlike traditional encryption methods.
2. What are the key challenges in implementing homomorphic encryption in real-world applications? One of the challenges is the computational overhead associated with homomorphic encryption, which can impact performance in certain use cases.
Original Abstract Submitted
disclosed is a homomorphic encryption operation apparatus and method. the homomorphic encryption operation method is performed by a computing device that includes processing hardware and storage hardware, and the method includes: receiving, and storing in the storage hardware, a ciphertext including modules; receiving, and storing in the storage hardware, an operation key including a relinearization key corresponding to the ciphertext; and performing, by the processing hardware, a homomorphic encryption operation on the ciphertext, wherein a modulus of the ciphertext is determined by the processing hardware based on a dimension of the modules and a number of the modules.
