“…There are several SHA3 variations including the SHA3-224-bit, SHA3-256-bit, SHA3-384-bit and SHA3-512-bit, it is made up of several rounds, each of which contains certain logical processes. It basically produces the required output by employing the sponge function, which absorbs input first before pressing it to produce the intended output [6].…”

Data security means protecting important information from unauthorised persons. In a security system, cryptography is the most secure method. Cryptography has many kinds, but the Advanced Encryption Standard (AES) is the most secure system. If combined with AES and Secure Hash Algorithm-3-512Bits (SHA3-512), it becomes compact, more secure, and more authenticated for data communications. The proposed methodology is a hybrid cryptography technique that combines AES with the SHA3-512 algorithm. This system becomes a strong, secure system and produces a strong cipher text. The proposed method AES/SHA3-512 is Hardware implementation on the Artix-7 FPGA family yields the lowest cost and highest hardware efficiency with a reduction in area usage of LUT 18.49%, Flip Flops 0.83%, and IO 3.8%. The proposed architecture is synthesised and simulated using the Vivado 2017.2 version Tool.

“…It comprises various rounds, which allows for more logical operations on each round. In order to absorb the input first, and then squeeze out the desired output [13], the sponge has been constructed. Initializing, absorbing, and squeezing the input message "M" results in three Sponge functions: Initializing, absorbing, and squeezing.…”

Cryptography is a security strategy that prevents disclosure of the information while it is transit, in storage, or both. There are a variety of methods for maintaining data security, including utilizing light weight speed algorithms for encryption and parameter validation. Many algorithms have originated in the area of information protection, helping to assure the validity of the information generated. These include the following algorithms: SHA-1, SHA-2, SHA-3, AES, RC5, RSA, and more. In order to secure the legitimacy of the information and monitoring data , the speed of encryption and authentication must be critical. . Due to the necessity of fast and secure algorithms, these features are required. In this work, modification of the SHA-3 algorithm by introducing a new function called (the keccak function), which has an extremely quick execution time and a high level of security, also versatile cryptographic function. This change is implemented via the 2D chaotic system, which is geared towards generating random values for constants for the SHA3 algorithm. These constants values are generated by the SHA3 algorithm, and so are random and unguessable by the intrude. Statistical tests conducted by the National Institute of Standards and Technology (NIST) effectively outperformed the randomness of a proposed approach .The proposed algorithm shows lower execution time compared to previous studies, which is 0.041616sec for 1MB. Index Terms — Cryptography, Hash function, keccak Function, SHA-3, Chaotic system.

“…SHA-2 and SHA-3 provide more extended hash value that is more complicated to break [11], [13], but they are more complex and not as time efficient as SHA-1 [14] [23], [24]. The increased number of rounds in SHA3 makes it less susceptible to collision resistance and preimage resistance attacks when measured against SHA2, MD5, and SHA1 and others [25] but the use of a sponge function construction can be considered neither as an advantage nor a disadvantage because this function is a new construction that is not yet very well analyzed [26].…”

Hashes are used to check the integrity of data. This paper modified SHA-1 by incorporating mixing method in every round for better diffusion. The modification increased the hash output to 192-bits. Increasing the output increases the strength because breaking the hash takes longer. Based on the different message types, avalanche percentage of modified SHA-1 showed better diffusion at 51.64%, higher than the target 50%, while SHA-1 achieved 46.61%. The average execution time noted for modified SHA-1 is 0.33 seconds while SHA-1 is 0.08 seconds. Time increases as the number of messages hashed increases; the difference is negligible in fewer messages. <a name="_Hlk507405879"></a>On character hits, that is - no same character in the same position, modified SHA-1 achieved lower hit rate because of the mixing method added. The modifications’ effectiveness was also evaluated using a hash test program. After inputting 1000 hashes from random strings, the result shows no duplicate hash.
