State-of-the-Art of Voice Assistance Technology, Mitigating Replay Attacks: A Comprehensive Discussion

In recent years, smart home assistants have become increasingly popular among consumers worldwide. These intelligent devices, powered by artificial intelligence and voice recognition technology, Smart home assistants bring convenience and effectiveness to handling daily activities and overseeing different aspects of our residences. Nevertheless, the expanding use of these assistants raises apprehensions regarding security and privacy due to heightened connectivity and data gathering capabilities. The intensity of security threats associated with these devices is alarming. Specifically, security concerns regarding replay attacks have emerged as a critical challenge. While various strategies have been proposed by researchers in this domain, there is a need for more robust mechanisms. This research paper proposes a novel approach to mitigate replay attacks by combining nonce numbers and timestamps. The proposed use of timestamp and nonce number methods in preventing replay attacks in smart home assistants is highly promising. The proposed solution enhances the security of voice commands transmitted between the user and the smart home assistant. By introducing unique nonce numbers and timestamps in the communication protocol, the system effectively detects and prevents the replaying of previously recorded commands.
