Data Encryption Standard (DES) is based on the Feistel block cipher, developed in 1971 by IBM cryptography researcher Horst Feistel. DES uses 16 rounds of the Feistel structure. But with the changes in recent years, the internet is starting to be used more to connect devices to each other. These devices can range from powerful computing devices, such as desktop computers and tablets, to resource constrained devices, When it comes to these constrained devices, using a different key for each round cryptography algorithms fail to provide necessary security and performance.

In modern communication systems, secret keys are used to secure sensitive information such as personal data, financial transactions and government secrets. However, the security of these systems is only as strong as the secrecy of the key utilized for encrypting and decrypting the data. The use of easy guessable or compromised keys can lead to unauthorized access, data breaches, and identity theft. Additionally, the distribution and management of secret keys present challenges such as key generation, key distribution, key revocation, and key renewal, which can be complex and costly. Therefore, finding secure and efficient methods to manage secret keys is crucial for ensuring the confidentiality, integrity, and availability of sensitive information in today's digital age. Therefore, to improve the security of the symmetric encryption algorithms, The new method to encrypt and decrypt the difference size files using multiple keys is proposed. In addition to investigate the impact of using multiple keys on the security and performance of symmetric algorithms. However, the multiple keys are generated previously using MD5 and SHA2. The chosen algorithms in this study are Blowfish and CAST, with chosen three modes of operation: CBC, CFB and CTR. The results presented in the paper demonstrated that the Blowfish algorithm with generated multiple keys outperforms in the CBC mode despite has the most encryption and decryption time-consuming and memory usage. Where the randomness of Blowfish with mode CBC and CTR is the best throughput then it follows Blowfish with mode CFB.

“…The stream cipher is one of the important branches of modern cryptography. The stream cipher systems depend basically on linear feedback shift register (LFSR) units [15], [16]. The Geffe generator can be defined by 3 maximum-length LFSRs whose lengths w1, w2, w3 are pairwise relatively prime, with nonlinear combining function.…”

This paper introduces a secure communication protocol that provides secured communication pathways to manipulate drones through unsecured communication. The deployment of the proposed protocol works through providing two secured communication paths; drones to the drone’s controller path and controller to data centre path. The first secured communication path has achieved a high level of security and privacy by using a modification of SHA-1 method and an advanced encryption method. The modification of the SHA-1 is called 83SHA-1. These modifications can increase rounds in the first stage up to 83 rounds, inject each round with expansion and S-Boxes procedures that are used in DES to extend length from 160 to 240 bits then reduce it from 240 to 160 bits. After hash data from the drone then use the advanced encryption method which is called Geffe-Genetic (GG) Encryption algorithm where three types of keys will be used for deception attackers. The second accomplishment is to ensure providing secure communication between the drone’s controller and datacentre by using RNA-RADG-CBC (RRCBC) encryption algorithm where will generate an initialization vector (IV) for cipher block chaining (CBC) randomly, generate keys, and propose an encryption/decryption method. The security analysis shows a promising high security level of drones’s data.
