Passwords constitute the main mean for authentication in computer systems. In order to maintain the user-related information at the service provider end, password hashing schemes (PHS) are utilized. The limited and old-fashioned solutions led the international cryptographic community to conduct the Password Hashing Competition (PHC). The competition will propose a small portfolio of schemes suitable for widespread usage until 2015. Embedded systems form a special application domain, utilizing devices with inherent computational limitations. Lightweight cryptography focuses in designing schemes for such devices and targets moderate levels of security. In this paper, a lightweight poly PHS suitable for lightweight cryptography is presented. At first, we design two lightweight versions of the PHC schemes Catena and PolyPassHash. Then, we integrate them and implement the proposed scheme – called LightPolyPHS. A fair comparison with similar proposals on mainstream computer is presented.
