Securing Machine‐Type Communications: A Survey on Privacy Threats and Countermeasures
Machine‐type communication (MTC) is a fundamental enabler of the Internet of Things (IoT) and emerging 5G/6G networks, supporting massive deployments of heterogeneous and resource‐constrained devices. However, large‐scale data collection, persistent connectivity, and limited device capabilities introduce critical privacy challenges that are not ...

Black Box Traceable Ciphertext Policy Attribute-Based Encryption Scheme
In the existing attribute-based encryption (ABE) scheme, the authority (i.e., private key generator (PKG)) is able to calculate and issue any user’s private key, which makes it completely trusted, which severely influences the applications of the ABE ...

LIMA: Local and Lightweight Mutual Authentication for VANETs
This work presents LIMA, a lightweight local authentication protocol for VANETs. It is a SAE J2735 compliant certificateless vehicle authentication that eliminates traditional PKI dependencies while providing geographic zone‐based security and time‐based attribute control.

Multi-Authority Ciphertext-Policy Attribute Based Encryption With Accountability
Attribute-based encryption (ABE) is a promising tool for implementing fine-grained access control.To solve the matters of security in single authority, access policy public, not traceable of malicious user,we proposed a scheme of multi-authority. Moreover, multi-authority may bring about the collusion of different authorities.In order to solve these ...

A ciphertext-policy attribute-based proxy re-encryption scheme for data sharing in public clouds
Ciphertext-policy attribute-based proxy re-encryption (CP-ABPRE) extends the traditional Proxy Re-Encryption (PRE) by allowing a semi-trusted proxy to transform a ciphertext under an access policy toanother ciphertext with the same plaintext under a new ...

Group-oriented ciphertext-policy attribute-based encryption with expressive access policy
Based on the study of the traditional attribute-based encryption,a scheme called group-oriented ciphertext-policy attribute-based encryption was proposed.In the scheme,the access policy consists of AND-gate and OR-gate.Users were split up into different ...

QuantumShield integrates quantum key distribution (QKD) with software‐defined networking (SDN) to provide information‐theoretic security for IoT systems. The framework enhances the BB84 protocol with adaptive QBER thresholding, achieving 97.2% attack detection accuracy and computational infeasibility against brute‐force attempts.
