Boomerang analysis is a type of differential attack that use two bits of key difference and comparing both to examine any differences in bit after encryption. This paper describe boomerang analysis of permutation function of three-dimensional Advanced Encryption Standard or 3D-AES. The objective of this paper is to analyze 3D-AES security using boomerang cryptanalysis. The new block cipher algorithm not been tested by boomerang analysis before. From boomerang cryptanalysis on 3D-AES block cipher, from the experiment and significance results, it can be concluded 3D-AES block cipher is secure using boomerang analysis
