N2 - In this era, user privacy is a very important issue and encryption is a general solution. However, the encryption technique cannot keep user privacy while the key is leaked under outside coercion. To solve this problem, the deniable encryption technique is a useful tool since it makes the user be able to answer the outside coercer with fake data and proofs. In this paper, we propose a deniable encryption scheme based on the LWE problem (Learning with Errors). We enhance the Regev LWE encryption scheme proposed in 2009 by increasing the probability of decryption failure. So the user can cheat the outsider with the fake message. We also apply the multi-distributional concept proposed by O’Neill et al. scheme to construct our deniable encryption scheme.
