LoRCA: Lightweight round block and stream cipher algorithms for IoV systems

The Internet of Vehicles (IoV) is a disruptive technology that has great impact on people's lifestyle and activities. Fully autonomous vehicles are the next generation connected cars. However, IoV systems suffer from several security threats could offset intended advantages. To address privacy issues, cryptographic non-cryptographic solutions should be adopted. traditional might burden network with further complexity computational overhead. This would translate into additional performance issues in already suffering big data large-scale challenges. In this context, lightweight needed to reduce required resources terms computations, power memory, optimize latency bandwidth. paper, we propose new cipher scheme, LoRCA, dynamic key-dependent structure provide confidentiality minimum resources' requirements. validate our solution's robustness efficiency within tests were performed. results show proposed solution strikes good balance between level performance. LoRCA ciphers achieve high throughput an enhancement at least 100% improvement as compared Advanced Encryption Standard (AES), 358% Simon, 388% for Speck 24% previous one round scheme.
