A New Multiplication Technique for LWE Based Fully Homomorphic Encryption
Uddipana Dowerah, Srinivasan Krishnaswamy · Letters of the IEEE Computer Society · 2020
We propose a new multiplication technique for LWE based fully homomorphic encryption schemes. Unlike previous schemes, multiplication does not increase the size of the ciphertext. As a result, there is no need for relinearization. The noise associated with it increases only linearly.
