Performance of Adder Architectures on Encrypted Integers

The fully Homomorphic encryption scheme is corner stone of privacy in an increasingly connected world. It allows to perform all kinds computations on encrypted data. Although, time bottleneck numerous applications real life. In this paper, a brief description made the homomorphic TFHE Illaria Chillota and others. TFHE, implemented c language library, improves bootstrapping execution FHEW 13 milliseconds. performs processing multitude logic gates. This variety it possible construct, implement five adder architectures compare them terms per gate. singleprocessor computing environment, Carry Look-ahead Adder completed two-integer addition 90 seconds, whereas Ripple carry did same 109 seconds. An improvement 15% observed. And, ratio about was obtained four integers, respectively for 279 seconds first 320 Wallace's dedicated adder. While dual-processor 50% seen adders integers. saw his handling improved by sum two numbers from 46 139 respectively.
