Multilayer Data Security Model for Handheld Devices with Simple Encryption Technique and Hardware Software Co-Design

Data transmission increases vastly and hence the crisis in data security arises. The transmitted data are subjected to various proceedings to ensure security. From the usual way of providing security in the presentation layer alone, it is strongly put forth to provide security in the other layers too. This could be done with the help of the Software Hardware co-design. Apart from the Encryption Techniques, small mechanism to screen the trusted users is provided in the Physical layer itself to enrich the strength of the security. Comparison is done with strong encryption and combined weak encryption and hardware technique.
