Abstract
Multi-layer key for AES encryption technique are present in this paper. LFSR and MD5 as a primary key layer was used to increase the security of the key. Three types of tests for ten round for each key layer are tested and analyzed. From the tests the MD5 is present as more suitable for security but it more complexity while LFSR is good for both. The usage of them will be depending on the natural of applications.
Keywords
