APPARATUS AND METHOD WITH HOMOMORPHIC ENCRYPTION - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240121076 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 processor in the apparatus generates a modulus switch ciphertext by applying modulus switching to the received data, maps a component of an input ciphertext to an odd number, generates a blind rotated ciphertext through a blind rotation operation based on the modulus switched ciphertext, and finally produces encrypted data as a homomorphic encryption operation result by performing key switching based on the blind rotated ciphertext.
- Modulus switching: The processor maps a component of the input ciphertext to an odd number.
- Blind rotation operation: A blind rotation operation is performed on the modulus switched ciphertext to generate a blind rotated ciphertext.
- Homomorphic encryption: Encrypted data is generated as a result of a homomorphic encryption operation based on the blind rotated ciphertext.
Potential Applications
The technology described in the patent application could be applied in secure communication systems, data encryption for sensitive information, and secure cloud computing.
Problems Solved
This technology helps in securing data transmission, protecting sensitive information from unauthorized access, and enabling secure computation on encrypted data.
Benefits
The benefits of this technology include enhanced data security, privacy protection, and the ability to perform computations on encrypted data without decrypting it.
Potential Commercial Applications
Potential commercial applications of this technology could include secure messaging apps, encrypted cloud storage services, and secure data processing platforms.
Possible Prior Art
One possible prior art for this technology could be the use of homomorphic encryption 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 data, making it harder for unauthorized parties to decipher the encrypted information.
What are the limitations of the modulus switching technique in terms of data encryption?
The modulus switching technique may have limitations in handling large volumes of data or complex encryption algorithms, which could impact the efficiency of the encryption process.
