摘要：Cryptography is a security technique that must be applied in both communication sides to protectthe data during its transmission through the network from all kinds of attack. On the sender side,the original data will be changed into different symbols or shapes by using a known key; this iscalled encryption. On the other communication side, the decryption process will be done and thedata will be returned to its former shape by using the agreed key. The importance of cryptographyis to fulfil the communication security requirements. Real time applications (RTA) are vulnerablefor the moment because of their big size. However, some of the current algorithms are not reallyappropriate for use with these kinds of information. In this paper, a novel symmetric block ciphercryptography algorithm has been illustrated and discussed. The system uses an 8x8x8 cube, andeach cell contains a pair of binary inputs. The cube can provide a huge number of combinationsthat can produce a very strong algorithm and a long key size. Due to the lightweight and fasttechnique used in this idea, it is expected to be extremely rapid compared to the majority of currentalgorithms, such as DES and AES
