| Abstract(in English) | Homomorphic encryption is the cryptographic system with additively or multiplicatively homomorphism. Paillier and RSA are as known as the examples which have those properties. In 2009, Gentry et.al. proposed the fully homomorphic encryption which has both additively and multiplicatively homomorphism. In this paper, we propose the algorithm to compare two different encrypted data using common key encryption. Common key encryption, considering its performance, we use the encryption based on non-commutative algebra and perform implementation with plaintext of 2048-bit. Moreover, we compare previous research and our result. |
