# Identifying Adversary Impact Using End User Verifiable Key with Permutation Framework
###### Abstract  
In the Internet of Things (IoT), security is a crucial aspect that ensures secure communication, transactions, and authentication for different applications. In IoT security, maintaining the user interface and platform security is a critical issue that needs to be addressed due to leaky security distribution. During communication, synchronisation and security are important problems. The security problems are caused by the adversary impact and vulnerable attacks, leading to service failure. Therefore, the Permutated Security Framework (PSF) is designed to manage security in the IoT by providing secure communication, transactions, and authentication for different applications. The PSF uses time intervals to manage transaction security. These intervals are secured using end-verifiable keys generated using the conventional Rivest-Shamir-Adleman (RSA) technique in IoT-based communication-related applications. In this approach, the key validity is first provided for the interval, and in the latter, the access permitted time modifies its validity. The security of transactions is managed by dividing time into smaller intervals and providing different levels of security for each interval. By using time intervals, the framework is adaptable and adjustable to changes in the system, such as user density and service allocation rate, adapting parallel transactions per support vector classifications' recommendations. The proposed framework aims to synchronise interval security, service allocation, and user flexibility to mitigate adversary impact, service failures, and service delays while improving the access rate and transactions. This allows for more flexibility and better management of transaction security. The proposed framework reduces adversary impact (10.98%), service failure (11.82%), and service delay (10.19%) and improves the access rate by 7.73% for different transactions.

and provide a better authentication process. Security is a major concern in IoT due to the large amount of data that needs to be managed. IoT is used in smart devices and wireless sensor networks (WSN) to enhance user services [2]. Proper authentication processes are used to address security issues, such as Authentication and Key Agreement (AKA) schemes. AKA schemes are applied in IoT to identify unauthorised persons from accessing the personal information of users [3]. A secret session key is shared with the users for the authentication process, and authentication will be declined without the key. AKA helps protect users from attackers by providing a better authentication process and maximising the system's performance by ensuring users' security and privacy. WSN is also used in security issues to find the users' exact location and identify intruders. While authenticating, a device's current location is traced, which helps to finalise the authentication process [4; 5]. The IoT is widely utilised in various applications to improve communication among organisations and users and provide better services. Data processing is one of the main tasks in IoT, which helps to improve user performance [6]. IoT enables users to transfer data or information from one person to another using smart devices. Data transaction or transfer allows users to send information from their current location without travelling [7]. However, data transfer may also cause some security threats, and a proper authentication process is needed to ensure a secure data processing system [8]. Privacy and security are major concerns in IoT while transferring data. To address these concerns, technologies such as radiofrequency identification (RFID) are used in IoT to enhance security and privacy. RFID interacts with tags of the information and provides a better solution to security issues [9]. RFID tags have electronic product codes for each transaction, which helps to track the exact whereabouts of the data being transferred.
