“…The restrictiveness property is essentially the guarantee for traceability in the restrictive blind signature systems. Partial blind signature schemes [28], [29] allow the resulting signature to convey publicly visible information on common agreements between the signer and the signee. This is useful when certain information in the signature needs to be reviewed by a third party.…”

Abstract-Anonymity has received increasing attention in the literature due to the users' awareness of their privacy nowadays. Anonymity provides protection for users to enjoy network services without being traced. While anonymity-related issues have been extensively studied in payment-based systems such as e-cash and peer-to-peer (P2P) systems, little effort has been devoted to wireless mesh networks (WMNs). On the other hand, the network authority requires conditional anonymity such that misbehaving entities in the network remain traceable. In this paper, we propose a security architecture to ensure unconditional anonymity for honest users and traceability of misbehaving users for network authorities in WMNs. The proposed architecture strives to resolve the conflicts between the anonymity and traceability objectives, in addition to guaranteeing fundamental security requirements including authentication, confidentiality, data integrity, and nonrepudiation. Thorough analysis on security and efficiency is incorporated, demonstrating the feasibility and effectiveness of the proposed architecture.

“…In this section, our proposed Identity-based partially based blind signature is compared in terms of computation cost, with existing scheme [5,6,7] shown in Table 1. Here, according to [6], we represent G 1 A as the point addition on elliptic curve G 1 , G 1 M as the point multiplication on elliptic curve G 1 , Pa denote as the pairing operation on elliptic curve, MTP represent as the map-to-point hashing operation, Z q M denotes the multiplication operation on Z q and Z q d denotes the division operation on Z q .…”

“…With the incorporated properties of blindness and Untraceability, it plays an important role in many e-commerce applications where user anonymity is the main concern such as e-payment system, e-wallet [3,4]. However, experts feel that fully blinded signature have some disadvantages, for example, except the public information; bank could not access the malicious customer for double spent money [5][6][7][8]. A kind of Blind Signature, partially blind signature allows a user to request the signatory authority on some pre-shared information such that signatory authority only sign the message but could not able to see to message's content except the preshared information.…”

Blind signature is a crucial technique to provide anonymity in many information systems such as e-cash, e-voting, and smart grid systems. Partially blind signature is a more applicable extension where the part of the message includes some common information known by the signer and the signature requestor. In the family of lattice-based schemes, blind signatures are given in ASIACRYPT 2010 by RR uckert in the random oracle model, and until now, no partially blind signatures are given. We here design the first scheme based on Lyubashevsky's signature scheme in EUROCRYPT 2012 and Abe and Okamoto's construction of partially blind signature in CRYPTO 2000 in the random oracle model. The scheme shows an alternative approach to achieve the blindness property without the supports of a commitment scheme and of a final round communication to confirm the validity of a signature.
