Abstract: Hybrid Cube (HC) is generated from a combination and permutation of integers. All possible combinations of hybrid cube layers are the source for the generation of encryption and decryption keys in the non-binary block cipher. This study extends the hybrid cube encryption algorithm (HiSea) and analyzing their security issues by increasing the complexity in mathematical approaches. Based on existing HC technique, this research proposed a new coordinate extraction technique for data security. For this purpose, four key matrices generated from HiSea of order 4. Each key matrix generates one row of a new matrix based on our proposed Triangular Coordinate Extraction (TCE) technique. The proposed technique undergoes the following phases; selecting the surface of HC, intersection of diagonals, TCE for Hybrid Cube surface (HCs) stages and extraction of coordinates during the rotation of HCs. The rotation has been needed in the development of ciphertext by rotating the plaintext and to obtaining the original plaintext from ciphertext.
