“…We call this scheme threshold attribute-based encryption (t-ABE) for describe simplicity. Yang et al [4] introduce a new cryptographic primitive called Fuzzy Identity Based Signature(FIBS) which the signature analogue of FIBE. Shahandashti et al [5] proposed a threshold attribute-based signature construction for small attribute universe and large attribute universe.…”

Attribute based signature (ABS) scheme is an important cryptographic primitive which provides a powerful way for user to control their privacy. However, the computational and storage cost of ABS is reasonable when the number of users involved in the system is huge. In order to reduce the bandwidth needed to transmit attribute based signatures and the time needed to verify them, we propose attribute based sequential aggregate signature (ABSAS) scheme. The ABSAS scheme allows a set of players to sign the different messages compress into a short signature which can greatly decrease the store space. In this paper, we also formalize ABSAS scheme and prove the security of this scheme in the standard model. The analysis shows that our ABSAS scheme has less signature length and need less verify computation than the traditional ABS which is more appropriate for the actual situation, especially where bandwidth is a bottleneck.

“…As a similar notion to ABS, fuzzy identity-based signature was proposed and formalized in [21,22], which enables users to generate signatures with part of their attributes. To achieve the same goal, the notion of attribute-based signature was given in [2], but Tan et al [23] pointed out that this scheme is vulnerable to the partial key replacement attack.…”

Attribute-based signature (ABS) is a new cryptographic primitive, in which a signer can sign a message with his attributes, and the verifier can only known whether the signer owns attributes satisfying his policy. Moreover, the signature cannot be forged by any user not having attributes satisfying the policy. ABS has many applications, such as anonymous authentication, and attribute-based messaging systems. But these applications may require a user to obtain attributes from different authorities, which calls for a multiauthority ABS scheme. In addition, multiple authorities can distribute the trust to all authorities, instead of concerning on a single attribute authority. In this paper, we propose a multi-authority ABS scheme, supporting complex policies, expressing AND, OR, and threshold conditions. We use a central authority to assure the usability of attribute keys a user getting from different attribute authorities. To prevent collusion attacks, we adopt a unique global identity (GID) for a user to bind his attribute keys and identity together. And a secret key from the central authority help the verification be independent of the user's identity. So our scheme can fit the requirements of real applications, and also distribute the trust to all authorities in the system.

“…As a similar notion, fuzzy identitybased signature was proposed and formalized in [6,25], which allows a user with attribute identity x to sign with part of his attributes. The verifier can check if the signature is signed by some user with these attributes.…”
