In this research, a recently proposed lightweight block cipher LBlock, not tested against the cube attack has been analyzed. 7, 8 and 9 round LBlock have been successfully attacked with complexities of O(210.76), O(211.11) and O(247.00) respectively. For the case of side channel cube attack, full version of LBlock has been attacked using a single bit leakage model with the complexity of O(255.00) cipher evaluations. For this purpose, a generic practical platform has been developed to test various stream and block ciphers against the latest cube attack.
