Abstract

Dividing the data into blocks and there by arranging the blocks in hierarchal order is termed as a linear hierarchical cipher approach for data .The encryption code, a access id code for each level based on the propagation code is generated in this technique. However the level propagation code and the access-id code of previous hierarchy level are matching with upper hierarchical level .The access-id code is set based on the time sensing key and a time seed, and the time seed updates with respect to the encryption pulse. By simply modifying and inversing the data security it is possible to decrease the number of key volume.
