“…The increasing demand for the confidentiality of information necessitates the creation of new encryption techniques and algorithms [1], [2], [5], [6]. According to William Stalling, the security of encrypted data is entirely dependent on two factors: the strength of the cryptographic technology and the secrecy of the key [7]. These algorithms must be fast and secure enough to prevent wasting resources in low constrain devices.…”

<span lang="EN-US">Encryption algorithms aim to make data secure enough to be decrypted by an attacker. This paper combines the Speck and the Salsa20 to make it difficult for an attacker to exploit any weaknesses in these two algorithms and create a new lightweight hybrid algorithm called Speck-Salsa20 algorithm for data integrity and confidentiality (SSDIC). SSDIC uses less energy and has an efficient throughput. It works well in both hardware and software and can handle a variety of explicit plaintext and key sizes. SSDIC solves the difficulties of the Speck algorithm. The sequence generated by Speck is not random and fails to meet an acceptable success rate when tested in statistical tests. It is processed by generating a random key using the Salsa20 algorithm. Salsa20 is a high-speed secure algorithm that is faster than advanced encryption standard (AES) and can be used on devices with low resources. It uses a 256-bit key hash function. The recovery of the right half of the original key of the Speck algorithm is also handled by modifying the Speck round function and the key schedule. Simulation results show, according to a National Institute of Standards and Technology (NIST) test, the performance achieved by the SSDIC is increased by nearly 66% more than that achieved from the Speck in terms of data integrity and confidentiality.</span>

“…Cryptographic analysts have successfully exploited any flaws in algorithm designs and there have been security breaches in [7]- [9]. To prevent a cryptanalyst from exploiting algorithm weaknesses, two or more algorithms are combined to create a new one called a hybrid cipher.…”
