A New Variable Length Key Block Cipher Technique For Network Security In Data Transmission

The algorithm that is going to be discussed in this work will consider a random matrix key which on execution of sequence of steps generates a sequence. Based on the equality of values, this sequence is being divided into basins. The basins with minimum values will be eliminated. Remaining each basin represents one block of data. Depending on starting input value of plain text character, corresponding basin is considered as a key. The procedure is repeated for certain plain text depending on chosen value. Thus the cipher text obtained becomes very difficult to be broken with out knowing the key.
