Encryption Symmetric secret Key in Wireless Sensor Network Using AES Algorithm

Abstract

Wireless sensor network (WSN) security is an important component for protecting data from an attacker. For improving security, cryptography technologies are divided into two kinds: symmetric and asymmetric. Therefore, the implementation of protocols for generating a secret key takes a long time in comparison to the sensor’s limitations, which decrease network throughput because they are based on an asymmetric method. The asymmetric algorithms are complex and decrease network throughput. In this paper, an encryption symmetric secret key in wireless sensor networks (WSN) is proposed. In this work, 24 experiments are proposed, which are encryption using the AES algorithm in the cases of 1 key, 10 keys, 25 keys, and 50 keys. In each experiment, two chains are combined by using a hash function (SHA-2) to produce secret keys. The Network Simulator Version 2 (NS2) was used to assess the network throughput for the generated key. The randomness of the suggested LWM method has been tested by using the Diehard statistical test and the Entropy test. The results of the tests show that the encryption secret keys have a high level of data randomness.

“…Key generation technique is one of the most important factors for improving network security [8,15]. Public-key schemes are asymmetric and require two keys, unlike typical one-key encryption based on mathematical functions [2]. Passwords can be lost, stolen, or compromised, which is the main drawback of using a key generation approach to ensure security.…”

“…The basis for user authentication in conventional cryptosystems is holding secret keys; this mechanism breaks down if the secrets are shared with unauthorized users. Furthermore, keys cannot offer non-repudiation because they might be misplaced, stolen, or forgotten [2]. The degree of security of a symmetric or asymmetric encryption system depends on how secret the cryptographic key or private key is [1,2].…”

“…Furthermore, keys cannot offer non-repudiation because they might be misplaced, stolen, or forgotten [2]. The degree of security of a symmetric or asymmetric encryption system depends on how secret the cryptographic key or private key is [1,2]. The information is secure when using different cryptographic techniques, including Rivest-Shamir-Adleman (RSA), Data Encryption Standard (DES), Triple DES (3DES), and Advanced Encryption Standard [1,3].…”

“…The system shall generate the same key for the same person, even if the biometric record is subject to different conditions. The system's security ensures that the user's biometric data is unique and that neither the key nor the biometric original can be traced or guessed [2,3]. Therefore, the ability of biometric-based security to provide security in sophisticated technologies is quite high [3].…”
