Honey encryption (HE) is a novel password-based encryption scheme which is secure against brute-force attack even if users' passwords have min-entropy. However, because decryption under a wrong key produces fake but valid-looking messages to everyone, typos in password may confuse even legitimate users in HE. This has been one of the most challenging problems in HE. In this paper, we propose two types of protocols that enable legitimate users to detect the typos in a password. We compare and analyze the performance and security of each scheme. The analysis results show that the proposed schemes can effectively solve the typos problem in HE while providing message recovery security.
