A public key infrastructure (PKI) is being deployed in a field of network security. PKCS#5 is one of the most popular standards in PKI framework, intended for the practical implementation of password-based cryptography. So, the PKCS#5 encryption must be useful for general software applications within multimedia systems. However, it has a critical weak point in terms of security such as being vulnerable to off-line attacks due to the password-derived encryption key. In this paper, we observe a practical and simple method to improve security of the PKCS#5 encryption without modifying the installed base. The idea is to hide a salt by exploiting several existing schemes.
