Privacy in wireless sensor networks using ring signature

Journal of King Saud University: Computer and Information Sciences, 2014
The veracity of a message from a sensor node must be verified in order to avoid a false reaction by the sink. This verification requires the authentication of the source node.

ID-based Ring Signature and Proxy Ring Signature Schemes from Bilinear Pairings

, 2005
In 2001, Rivest et al. firstly introduced the concept of ring signatures. A ring signature is a simplified group signature without any manager. It protects the anonymity of a signer. The first scheme proposed by Rivest et al. was based on RSA cryptosystem and certificate based public key setting.

Ring adaptor signature scheme based on SM2 digital signature algorithm

网络与信息安全学报
Adaptor signature can guarantee the atomicity of cross-chain transactions without relying on trusted third parties, but most adaptor signature algorithms fail to protect the privacy of user identities.

Property-Based Anonymous Attestation in Trusted Cloud Computing

Journal of Electrical and Computer Engineering, 2014
In the remote attestation on Trusted Computer (TC) computing mode TCCP, the trusted computer TC has an excessive burden, and anonymity and platform configuration information security of computing nodes cannot be guaranteed.

Efficient Identity Based Ring Signature [PDF]

, 2005
Identity-based (ID-based) cryptosystems eliminate the need for validity checking of the certificates and the need for registering for a certificate before getting the public key. These two features are desirable especially for the efficiency and the real spontaneity of ring signature, where a user can anonymously sign a message on behalf of a group of ...

Identity-based Linkable Ring Signcryption on NTRU Lattice [PDF]

Jisuanji kexue
Although the current lattice-based ring signcryption scheme resists quantum attacks,it has large key storage and high encryption/decryption time.The linkable lattice ring signcryption scheme not only can protect signer anonymity,but also can determine ...

Identity-based ring signature scheme under standard model

Tongxin xuebao, 2008
An identity based ring signature scheme using the method of Waters for constructing private key was presented. This scheme is secure in the standard model under the computational Diffie-Hellman assumption.
