Graph design for data authentication over insecure communication channel

open access: yesAlexandria Engineering Journal, 2023
Data authentication is a critical issue in communication systems. Based on data authentication techniques, the receiver can affirm that the data is really sent from an authentic sender and it is not a fabricated message from an opponent.

Message Authentication, Revisited [PDF]

open access: yes, 2012
Traditionally, symmetric-key message authentication codes (MACs) are easily built from pseudorandom functions (PRFs). In this work we propose a wide variety of other approaches to building efficient MACs, without going through a PRF first. In particular, unlike deterministic PRF-based MACs, where each message has a unique valid tag, we give a number of

Information-Theoretically Secure Data Origin Authentication with Quantum and Classical Resources

open access: yesCryptography, 2020
In conventional cryptography, information-theoretically secure message authentication can be achieved by means of universal hash functions, and requires that the two legitimate users share a random secret key, which is at least twice as long as the tag ...

Authentication of satellite navigation signals by wiretap coding and artificial noise

open access: yesEURASIP Journal on Wireless Communications and Networking, 2019
In order to combat the spoofing of global navigation satellite system (GNSS) signals, we propose a novel signal authentication method based on information-theoretic security.

Group Message Authentication [PDF]

open access: yes, 2010
Group signatures is a powerful primitive with many practical applications, allowing a group of parties to share a signature functionality, while protecting the anonymity of the signer. However, despite intensive research in the past years, there is still no fully satisfactory implementation of group signatures in the plain model.

Efficient authentication scheme for cross-trust domain of IoV based on double-layer shard blockchain

open access: yesTongxin xuebao, 2023
To solve the problems of poor scalability, slow synchronization of authentication information, and high authentication overhead in cross-trust domain message authentication in the Internet of vehicles (IoV), an efficient authentication scheme for cross ...

A Secure Pseudonym-Based Conditional Privacy-Preservation Authentication Scheme in Vehicular Ad Hoc Networks

open access: yesSensors, 2022
Existing identity-based schemes utilized in Vehicular Ad hoc Networks (VANETs) rely on roadside units to offer conditional privacy-preservation authentication and are vulnerable to insider attacks.

A Routing Path Construction Method for Key Dissemination Messages in Sensor Networks

open access: yesThe Scientific World Journal, 2014
Authentication is an important security mechanism for detecting forged messages in a sensor network. Each cluster head (CH) in dynamic key distribution schemes forwards a key dissemination message that contains encrypted authentication keys within its ...
