“…The performance of random Speck exceeds the acceptable success rate, indicating that the algorithm's sequence is insecure [21], [22]. Because Speck requires the key to be supplied alongside the plaintext to be encrypted, as well as the good attack point in a side-channel attack is where the plaintext directly mixes with the key.…”

<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>

“…The key properties of lightweight cryptography primitives [41], [42], [200], [201], [192]- [199] are listed in Table VI which summarizes different encryption algorithms and their characteristics including algorithm structures, key size, security strength and their implementation environment. Based on the literature, the security strength of cryptographic primitives can be measured as follows: low = below 55%; good = 55% to 69%; very good = 70% to 85%; excellent = 86% and above [41], [42], [200], [201], [192]- [199]. For instance, if an algorithm is capabe of providing 90% protection of a system then the security strength is considered excellent.…”

“…Being ARX structure, SPECK was evaluated [20] by formulating SAT/SMT model for Rotational-XOR cryptanalysis. Prior studies relate to its enhancement on the randomness of key-schedule for more secured block cipher and perform faster encryption in software implementation [21].…”

Lightweight Block Cipher's (LBC) various algorithms need to meet the security requirements for all resource-constrained devices and Internet of Things (IoT) technologies. Various LBC addressed such concerns as the SIMON and SPECK block ciphers, which are known for security and performance. SIMECK, a combination of SIMON and SPECK, shows better performance. However, the SIMECK round function remains a concern. This paper aims to present a modification on the SIMECK round function method simulated on its circular and ARX structure. It took at least seven attempts to reach the appropriate structure. The seventh modification had a circular parameter of (3,5) and a change of right-shift on the structure. The results show that the modified round function achieves 54.58% average on the avalanche effect, the runtime performance of 1.3945ms with a randomness p-value of 0.46931 compared with p-value 0.51512 of the original algorithm. The study explores the ARX structure of LBC, which leads to a good venue to implement with other block ciphers. It is recommended that further evaluation of the modified algorithm will be conducted to test its efficiency, like to verify its vulnerability through different attacks.
