Abstract
Disclosed is a method of processing an encrypted message. The method of processing an encrypted message includes checking exponential data and mantissa data for numerical data, performing homomorphic encryption on the mantissa data, and merging the encrypted mantissa data and the exponential data to generate a homomorphic encrypted message.
Claims14
A method of processing an encrypted message in an arithmetic unit, the method comprising:
- checking exponential data and mantissa data for numerical data;
- performing homomorphic encryption on the mantissa data;
- and
- merging the encrypted mantissa data and the exponential data to generate a homomorphic encrypted message.
1 more element
An arithmetic unit, comprising:
- a memory configured to store numerical data;
- and
- a processor configured to generate a homomorphic encrypted message for the numerical data,
- wherein the processor checks exponential data and mantissa data for numerical data, homomorphically encrypts the checked mantissa data, and merges the encrypted mantissa data and the exponential data to generate the homomorphic encrypted message.
