Abstract
Cellular Message Encryption Algorithm (CMEA) has been widely used for wireless security and the breaking of the scheme proves the requirement of alternatives. In the current paper the properties of the CMEA, which has lead to the successful cryptanalysis, has been identified. Accordingly the algorithm has been modified to prevent the attacks. Finally the customized CMEA has been subjected to standard linear and differential cryptanalysis to evaluate its security margin. The endeavour demonstrates that with appropriate modifications the CMEA can be transformed into a strong cipher, which is essential for wireless security.
