摘要：Data security has become a very important aspect in recent years due to drastic progress in the use ofinternet. Many ciphers have been developed to provide data security but all the conventional encryption techniques haveproved to be weak and amenable to attack even by use of brute force and traditional cryptanalysis. Caesar cipher is thesimplest and weakest because it can be simply attacked by brute force cryptanalysis. This work proposes an improvementover Caesar cipher by using row shift and column transformations. The improvement will no doubt eliminate theweakness of the Caesar cipher and provide cipher text that is harder to crack.
