APPARATUS AND METHOD WITH HOMOMORPHIC ENCRYPTION - A simplified explanation of the abstract
This abstract first appeared for US patent application 18301343 titled 'APPARATUS AND METHOD WITH HOMOMORPHIC ENCRYPTION
Simplified Explanation
The apparatus described in the patent application is designed to perform various encryption operations on data received by a receiver. The operations include modulus switching, blind rotation, and key switching to generate encrypted data as a homomorphic encryption operation result.
- Modulus switching: Mapping a component of an input ciphertext generated from the received data to an odd number.
- Blind rotation: Performing a blind rotation operation based on the modulus switched ciphertext.
- Key switching: Generating encrypted data by performing key switching based on the blind rotated ciphertext.
Potential Applications
The technology described in the patent application could have potential applications in secure communication systems, data encryption for sensitive information, and privacy-preserving data analysis.
Problems Solved
This technology helps in securing data during transmission and storage, protecting sensitive information from unauthorized access, and enabling secure computation on encrypted data without revealing the underlying information.
Benefits
The benefits of this technology include enhanced data security, privacy protection, secure computation capabilities, and the ability to perform operations on encrypted data without decrypting it.
Potential Commercial Applications
- Secure messaging applications
- Financial data encryption services
- Healthcare data protection solutions
Possible Prior Art
One possible prior art for this technology could be the use of homomorphic encryption techniques in secure communication systems and data protection applications.
Unanswered Questions
How does the blind rotation operation enhance the security of the encrypted data?
The blind rotation operation helps in further obfuscating the ciphertext, making it harder for attackers to decipher the original data.
What are the computational requirements for performing key switching in this encryption scheme?
The computational requirements for key switching may vary depending on the size of the ciphertext and the complexity of the encryption keys used.
Original Abstract Submitted
An apparatus including a receiver and a processor configured to generate a modulus switch ciphertext by performing modulus switching with respect to data received by the receiver, the modulus switching including mapping a component of an input ciphertext generated from the received data to an odd number, generate a blind rotated ciphertext by performing a blind rotation operation based on the modulus switched ciphertext, and generate encrypted data, as a homomorphic encryption operation result, by performing key switching based on the blind rotated ciphertext.
