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

LoRCA:车联网系统的轻量级圆块和流密码算法

车联网(IoV)是一项颠覆性技术,对人们的生活方式和活动产生重大影响。全自动驾驶汽车是下一代联网汽车。但是,IoV 系统受到多种安全威胁的影响,这些威胁可能会抵消预期的优势。为了解决安全和隐私问题,应采用多种加密和非加密安全解决方案。然而,传统的安全解决方案可能会给车联网网络带来更多的复杂性和计算开销。这将在已经遭受大数据和大规模挑战的网络中转化为额外的性能问题。在这种情况下,需要轻量级的安全解决方案来减少计算、功率和内存方面所需的资源,并在延迟和带宽方面优化网络性能。在本文中,我们提出了一种新的轻量级密码方案 LoRCA,它具有动态密钥相关结构,以最少的资源要求提供数据机密性。为了验证我们的解决方案在车联网环境中的稳健性和效率,我们进行了多项性能和安全测试。结果表明,所提出的解决方案在安全级别和性能之间取得了良好的平衡。提出的 LoRCA 密码实现了高吞吐量,与高级加密标准 (AES) 相比至少提高了 100%,与 Simon 相比提高了 358%,Speck 提高了 388%,与我们之前的一轮密码相比提高了 24%方案。LoRCA,具有动态密钥依赖结构,以最低资源要求提供数据机密性。为了验证我们的解决方案在车联网环境中的稳健性和效率,我们进行了多项性能和安全测试。结果表明,所提出的解决方案在安全级别和性能之间取得了良好的平衡。所提出的 LoRCA 密码实现了高吞吐量,与高级加密标准 (AES) 相比至少提高了 100%,与 Simon 相比提高了 358%,Speck 提高了 388%,与我们之前的一轮密码相比提高了 24%方案。LoRCA,具有动态密钥依赖结构,以最低资源要求提供数据机密性。为了验证我们的解决方案在车联网环境中的稳健性和效率,我们进行了多项性能和安全测试。结果表明,所提出的解决方案在安全级别和性能之间取得了良好的平衡。所提出的 LoRCA 密码实现了高吞吐量,与高级加密标准 (AES) 相比至少提高了 100%,与 Simon 相比提高了 358%,Speck 提高了 388%,与我们之前的一轮密码相比提高了 24%方案。进行了多项性能和安全测试。结果表明,所提出的解决方案在安全级别和性能之间取得了良好的平衡。所提出的 LoRCA 密码实现了高吞吐量,与高级加密标准 (AES) 相比至少提高了 100%,与 Simon 相比提高了 358%,Speck 提高了 388%,与我们之前的一轮密码相比提高了 24%方案。进行了多项性能和安全测试。结果表明,所提出的解决方案在安全级别和性能之间取得了良好的平衡。所提出的 LoRCA 密码实现了高吞吐量,与高级加密标准 (AES) 相比至少提高了 100%,与 Simon 相比提高了 358%,Speck 提高了 388%,与我们之前的一轮密码相比提高了 24%方案。
