A security enhanced password authentication and update scheme based on elliptic curve cryptography

As two fundamental requirements to ensure secure communications over an insecure public network channel, password authentication and update of password have received considerable attention. To satisfy the above two requirements, Islam et al. proposed a password authentication and update scheme based on elliptic curve cryptography. They claimed that their scheme could withstand various attacks. ...

An ECC-Based Mutual Authentication Scheme with One Time Signature (OTS) in Advanced Metering Infrastructure

Advanced metering infrastructure (AMI) is a key part of the smart grid; thus, one of the most important concerns is to offer a secure mutual authentication.  This study focuses on communication between a smart meter and a server on the utility side. Hence, a mutual authentication mechanism in AMI is presented based on the elliptic curve cryptography (ECC) and one time signature (OTS) consists o...

Note on 'Design of improved password authentication and update scheme based on elliptic curve cryptography'

Secured password authentication and update of passwords are two essential requirements for remote login over unreliable networks. In this paper, an elliptic curve cryptography (ECC) based technique has been proposed that not only satisfies the above two requirements, but also provides additional security requirements that are not available in some schemes proposed so far. For instances, the Pey...

Cryptanalysis on 'Robust Biometrics-Based Authentication Scheme for Multi-server Environment'

Authentication plays an important role in an open network environment in order to authenticate two communication parties among each other. Authentication protocols should protect the sensitive information against a malicious adversary by providing a variety of services, such as authentication, user credentials’ privacy, user revocation and re-registration, when the smart card is lost/stolen or ...
