A Secure Identity Authentication Scheme Based on Blockchain and Identity-based Cryptography

2019 IEEE 2nd International Conference on Computer and Communication Engineering Technology (CCET), 2019
Most blockchain-based identity authentication systems focus on using blockchain to establish the public key infrastructure (PKI). It can solve the problem of single point of failure and certificate transparency faced by traditional PKI systems, but there

Secure V2V Communication with Identity-based Cryptography from License Plate Recognition

International Conference on Internet of Things: Systems, Management and Security, 2019
The deployment of secure vehicle-to-vehicle communication is essential for recent technologies such as autonomous driving and traffic optimizations. In this paper we experiment with the use of license plates as a mean to identify vehicles and use this ...

Blockchain-based Distributed Identity Cryptography Key Management

International Conference on Computer Research and Development, 2023
The identity-based cryptography algorithm SM9 requires a trusted third-party key generation center KGC to generate the user's private key. This will bring the risks and problems of key escrow and single point failure.

Secure and Efficient Two-Party Signing Protocol for the Identity-Based Signature Scheme in the IEEE P1363 Standard for Public Key Cryptography

IEEE Transactions on Dependable and Secure Computing, 2020
Mobile device and application (app) security are increasingly important, partly due to the constant and fast-paced cyberthreat evolution. To ensure the security of communication (e.g., data-in-transit), a number of identity-based signature schemes have ...

Multi-identity management for identity-based cryptography

Journal of Discrete Mathematical Sciences and Cryptography, 2008
Abstract In identity-based (or ID-based) cryptography, user identities can be employed as public keys, where each public key maps a unique private key generated by a trusted authority usually called Private Key Generator (PKG). In some situations, a user could hold multiple identities; therefore, he has to manage the same number of private keys.

Identity-Based Cryptography in Credit Card Payments

2014
In this paper we describe how to apply identity based cryptography to credit card payments. This would help with reducing the possibility of credit card fraud that is prevalent on the Internet. Our method is founded on the identity-based cryptography and it secures the credit card transactions in such a way that many types of credit card fraud become ...

DOPIV: Post-Quantum Secure Identity-Based Data Outsourcing with Public Integrity Verification in Cloud Storage

IEEE Transactions on Services Computing, 2022
Public verification enables cloud users to employ a third party auditor (TPA) to check the data integrity. However, recent breakthrough results on quantum computers indicate that applying quantum computers in clouds would be realized.

Simple Identity-Based Cryptography with Mediated RSA [PDF]

, 2003
In this paper, we present a general framework for evaluating the performance characteristics of block cipher structures composed of S-boxes and Maximum Distance Separable (MDS) mappings. In particular, we examine nested Substitution-Permutation Networks (SPNs) and Feistel networks with round functions composed of S-boxes and MDS mappings.

An Efficient Identity-Based Provable Data Possession Protocol With Compressed Cloud Storage

IEEE Transactions on Information Forensics and Security, 2022
Cloud storage is more and more prevalent in practice, and thus how to check its integrity becomes increasingly essential. A classical solution is identity-based (ID-based) provable data possession (PDP), which supports certificateless cloud storage ...
