Therefore, the newlinedata increase has revolutionized technology in the current era, which is known as BigtData. newlineNowadays, onetof thetvitaltchallenges istto securetBig Data. newlineData security is represented by cryptography that can be defined as converting newlineplaintexttintotciphertexttand reversing from ciphertext into plaintext. These operations are newlinecalledtencryptiontandtdecryption by using a cipher. newlineConventional cryptography has different standard algorithms like thetAdvancedt newlineEncryptiontStandard (AES) algorithm, andtDatatEncryptiontStandardt (DES) talgorithm. newlineHowever, the security level is not strong in DES compared with AES.

Due to the ubiquitous tremendous development of technology, traditional newlinealgorithms must be updated with other algorithms that are compatible with the newlinecharacteristics of Big Data. This thesis is dedicated to provide solutions to this problem newlineXV newlinethrough presenting two algorithms to encrypt big data and one algorithm to authenticate the newlinebig data. newlineIn the first proposed algorithm, a technique has been adopted totsecuretdatatviata newlineproposedtnew blocktcipherttechniquettotprocesstmoretthantonetblocktbytdividingtthettotal newlinesizetof thetblocktinto twotparts, tswapping them, co
