This work proposes a new trust management system (TMS) for the Internet of Things (IoT).
The wide majority of these systems are today bound to the assessment of trustworthiness …

Since the appearance of the authors' first volume on elliptic curve cryptography in 1999
there has been tremendous progress in the field. In some topics, particularly point counting …

A proxy signature scheme permits an entity to delegate its signing rights to another. These
schemes have been suggested for use in numerous applications, particularly in distributed …

Due to avoiding the inherent escrow of identity-based cryptography and yet not requiring
certificates to guarantee the authenticity of public keys, certificateless public key …

In this paper, we propose the security notion of certificate-based signature that uses the
same parameters and certificate revocation strategy as the encryption scheme presented at …

A blind signature scheme is a protocol for obtaining a digital signature from a signer, but the
signer can neither learn the messages he/she sign nor the signatures the recipients obtain …

Ring signature allows specifying a set of possible signers without revealing which member
actually produces the signature. This concept was first formalized in 2001 by Rivest, Shamir …

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 …

Linearly homomorphic signature schemes allow the performance of linear computations on
authenticated data. They are important primitives for many applications, such as electronic …

In threshold ring signature schemes, any group of t entities spontaneously conscript
arbitrarily n–t entities to generate a publicly verifiable t-out-of-n signature on behalf of the …
