“…Also, each round in the AES algorithm needs round key from the key expansion algorithm. So the AES algorithm depends on the speed of the round key www.ijacsa.thesai.org generation [16]. In contrast, the ETSFS algorithm needs the key generation only one time before doing the encrypt function.…”

“…Moreover, hardware issues may cause inconsistent relations. The AES algorithm consumes more time than the ETSFS algorithm for selecting queries because in the AES algorithm, the decryption module depends mainly on the key expansion module [16]. Also, the execution of the query that retrieves the complete table consumes little more time than those that depend on the condition because the former retrieves more tuples than the latter; this tuples need more decryption operations.…”

Abstract-Virtually all of today's organizations store their data in huge databases to retrieve, manipulate and share them in an efficient way. Due to the popularity of databases for storing important and critical data, they are becoming subject to an overwhelming range of threats, such as unauthorized access. Such a threat can result in severe financial or privacy problems, as well as other corruptions. To tackle possible threats, numerous security mechanisms have emerged to protect data housed in databases. Among the most successful database security mechanisms is database encryption. This has the potential to secure the data at rest by converting the data into a form that cannot be easily understood by unauthorized persons. Many encryption algorithms have been proposed, such as Transposition-Substitution-Folding-Shifting encryption algorithm (TSFS), Data Encryption Standard (DES), and Advanced Encryption Standard (AES) algorithms. Each algorithm has advantages and disadvantages, leaving room for optimization in different ways. This paper proposes enhancing the TSFS algorithm by extending its data set to special characters, as well as correcting its substitution and shifting steps to avoid the errors occurring during the decryption process. Experimental results demonstrate the superiority of the proposed algorithm, as it has outperformed the well-established benchmark algorithms, DES and AES, in terms of query execution time and database added size.
