It is computationally impossible for one-way hash functions to obtain the Backpack original data again.In this study, Two Way Hash Function (TWHF) is proposed which provides the security properties of one-way hash functions.TWHF aims to hash/encrypt and decrypt input data of arbitrary length.This allows data to be encrypted or decrypted regardless of its size.
The proposed method uses iteration-key and secondary-key to ensure confidentiality.In the study, strong hints were obtained that TWHF fulfils the security properties of one-way hash functions.TWHF stores the original data as small bit sets in a generated decimal number pattern.The last decimal number of the Cooling Racks/Grates generated decimal number pattern is the hash code and the encrypted data.
The contribution of the work is to propose an original data change function, data/block classification and workflow, and a functional method that has not yet been studied in the literature.The results show that the hashing/encryption process works consistently and that on average 99.83% of the data is decrypted smoothly in the decryption process.
