| | | | | The Okamoto-Uchiyama cryptosystem is a semantically secure, asymmetric encryption algorithm. It was first introduced in 1998 by Tatsuaki Okamoto and Shigenori Uchiyama. The method is additive-homomorphic, which means that the plaintexts are added by multiplying two ciphertexts. It is therefore not necessary to decrypt the ciphertexts in order to be able to operate on the plaintexts. While searching for implementations of this algorithm on github, I realized that there were only two rough implementations. | |

| | | | | In this article I'll derive a trick used in FHE called sample extraction. In brief, it allows one to partially convert a ciphertext in the Ring Learning With Errors (RLWE) scheme to the Learning With Errors (LWE) scheme. Here are some other articles I've written about other FHE building blocks, though they are not prerequisites... | |
