Abstract

Linkable ring signatures can simultaneously provide the properties of anonymity, spontaneity as well as linkability. Linear feed-back shift register (LFSR) sequence can be used to shorten the representation of elements in a field. This paper proposes an LFSR-based linkable ring signature scheme, whose main computation operations are performed in base field GF(q) whereas security properties are under the state based discrete logarithm assumption (S-DLA) (and a new state based computational assumption weaker than state based decisional Diffie-Hellman assumption). The latter potentially says that the scheme is secure in the extension field GF(qd)(d the stage of the LFSR). All these make our scheme a flexible primitive for ubiquitous computing in which information processing has been thoroughly integrated into everyday objects and activities.
