Abstract: The day to day amplification on technology and the demand on shrinking the device sizes reflect in the diminution on memory sizes and constraints on device outlay. In the present times of mass communication with the swift escalating technology, there is a dire necessity for security on the information traversing between authorized individuals. All these factors invite the property of light weightiness and the focused security algorithms such as Hummingbird for devices with humiliated resources. This study present an efficient software implementation of modified Humming Bird algorithm on an 8-bit microcontroller with randomization on sub-key selection based on LFSR. We also do comparative analysis on performance in terms of memory foot print and execution time between our modified one and the original algorithm implementations. The obtained results make it evident that the proposed method raises the complexity significantly without hike in resource consumption and makes it more suitable to provide security in extremely constrained devices.
