In identity-based ring signatures (IBRS) (Zhang and Kim, 2002), a binary string ID∈{0,1}L for L∈N, representing a unique information about a signer (e.g., e-mail address, telephone number), is associated with a secret-key. Its owner can anonymously signs a message under a set of IDs called ring including the signer’s ID. Wildcarded IBRS (WIBRS) (Ishizaka&Kiyomoto, ISC’20) is a generalization of IBRS, in which the ring consists of wildcarded IDs. The signer correctly signs iff her ID matches at least one of the wildcarded IDs. To the best of our knowledge, the only one known WIBRS scheme adaptively secure under standard assumptions is obtained as an instantiation of the attribute-based signatures scheme by Sakai et al. (PKC’16). It has signatures of length O(kL) and secret-keys of (constant) length O(1), where k denotes cardinality of the ring. In this paper, we propose a generic WIBRS construction, built by linearly homomorphic signatures and non-interactive witness-indistinguishable proof. We instantiate it to obtain a concrete WIBRS scheme secure under standard assumptions, whose length of signatures (resp. secret-keys) O(k+L) (resp. O(L)).
