“…The 56-bit keys required by the original DES symmetric encryption technique were insufficient by 1999 to fend against actual brute force attacks. For a total key length of 168 bits, Triple DES calls for the usage of three different DES keys [7].…”

Cryptography is the practice of secure communication and the study of secure communication techniques. The theoretical foundations of cryptography include concepts such as cryptography, secure key exchange, digital signatures, and authentication. These technologies are used to protect the confidentiality, integrity, and reliability of information while it is being transmitted over a network or stored in digital form. The core of encryption is the concept of an encryption algorithm, which is a set of mathematical rules used to encrypt and decrypt data. The security of a cryptographic system depends on the strength of the underlying algorithm and the confidentiality of the key used to encrypt and decrypt the data. In this paper, Cryptography concepts and modern techniques are reviewed for types of encryption algorithms and the best ones, and many types of attacks and their impact on the encryption process

“…Rijndael algorithm have been selected as the AES by NIST in 2001 among several encryption candidates to be the official standard [9], [31]. Data are encrypted-decrypted on 128-bit blocks using a secret key of three options, 128, 192, or 256 bits' length.…”

“…Other works suggest using lightweight encryption as a low-power, memory-efficient encryption standard that requires low computing power [6]. In [7], [8], two comprehensive reviews have been conducted on the literature relating to encryption standards used for IoT applications. The reviews concluded that classic encryption standards like AES, DES, RSA and TDES cannot be used efficiently due to their complex implementation requiring large memory and high computing facilities.…”

“…The reviews concluded that classic encryption standards like AES, DES, RSA and TDES cannot be used efficiently due to their complex implementation requiring large memory and high computing facilities. A performance comparison between the advanced encryption standard (AES) and the extended tiny encryption algorithm (XTEA) for IoT applications is given in [9]. XTEA is a lightweight encryption standard while AES is a traditional encryption standard for IT.…”

A large number of sensors and intelligent devices are interconnected via the internet to collect data as part of the internet of things (IoT) applications. Data security is one of the important challenges for these applications due to vulnerability of the internet. IoT devices limiting factors, such as delay-sensitivity, restricted memory, and low computing capability, make choosing the appropriate data encryption standard extremely important. The current research focuses on evaluating four data security, block cipher standards for the IoT smart home application. Considering the encryption/decryption speed, DES, TDES, AES, and SAFER+ standards are evaluated by implementing the algorithms with MATLAB to determine the best security solution. The simulation of the four standards shows the superiority of SAFER+ standard in term of encryption speed compared to others added to its capabilities on security, and software implementation opportunity. The use of classical symmetric key standards for real time data security in the IoT application can be validated through the selection of SAFER+.

“…As with any asymmetric technique, RSA uses two key pairs for encrypting and decrypting data. The data are encrypted with a public key shared with other users, while the private key is only used to decrypt the data and must be secret [37]. The encryption and decryption processes in the RSA algorithm could be calculated as follows:…”

The need for cloud storage grows day after day due to its reliable and scalable nature. The storage and maintenance of user data at a remote location are severe issues due to the difficulty of ensuring data privacy and confidentiality. Some security issues within current cloud systems are managed by a cloud third party (CTP), who may turn into an untrustworthy insider part. This paper presents an automated Encryption/Decryption System for Cloud Data Storage (AEDS) based on hybrid cryptography algorithms to improve data security and ensure confidentiality without interference from CTP. Three encryption approaches are implemented to achieve high performance and efficiency: Automated Sequential Cryptography (ASC), Automated Random Cryptography (ARC), and Improved Automated Random Cryptography (IARC) for data blocks. In the IARC approach, we have presented a novel encryption strategy by converting the static S-box in the AES algorithm to a dynamic S-box. Furthermore, the algorithms RSA and Twofish are used to encrypt the generated keys to enhance privacy issues. We have evaluated our approaches with other existing symmetrical key algorithms such as DES, 3DES, and RC2. Although the two proposed ARC and ASC approaches are more complicated, they take less time than DES, DES3, and RC2 in processing the data and obtaining better performance in data throughput and confidentiality. ARC outperformed all of the other algorithms in the comparison. The ARC’s encrypting process has saved time compared with other algorithms, where its encryption time has been recorded as 22.58 s for a 500 MB file size, while the DES, 3DES, and RC2 have completed the encryption process in 44.43, 135.65, and 66.91 s, respectively, for the same file size. Nevertheless, when the file sizes increased to 2.2 GB, the ASC proved its efficiency in completing the encryption process in less time.
