Assignment Description
The majority of modern cryptographic algorithms were designed for desktop/server
environments, many of these algorithms could not be implemented in the low-power devices
used in applications such as automotive systems, sensor networks, healthcare, distributed
control systems, the Internet of Things (IoT), cyber-physical systems, and the smart grid.
Security and privacy is important in all of these areas. The lightweight cryptography has the
goal of providing cryptographic solutions that need to maintain the resource vs security
constraint.
In this context write a report including the following sections:
A. Introduction about the lightweight cryptography and its goals
B. The potential security threats in systems using low-power devices
C. The working mechanism of lightweight cryptography
D. Performance metrics (Hardware-specific metrics and Software-specific metrics)
E. Lightweight cryptographic algorithms
F. Cu
ent and Future challenges in lightweight cryptography
G. Conclusion
H. References
The Viva voce of the assignment will take place during Laboratory session in Week 7. The
student has to answer the viva questions related to the assignment.
Assignment Instructions:
 Do not use Wikipedia as a source or a reference
 Must consider at least five cu
ent references from journal/conference papers and
ooks. Must follow IEEE referencing style.
 Make sure you properly reference any diagrams/ graphics used in the assignment.

					Lightweight cryptography 
Introduction
As world is developing electronically latest gadgets are likewise getting created that consist of good battery and great performance, constrained assets, execution time. The New threats are moreover occurred on this type of gadgets hence there is a need to give more thoughtful privacy and security. In market, previous cryptography algorithms give great safety however consumes high battery power. So there is requirement of designing good encryption algorithm with high security and consume less battery power.  Lightweight cryptography algorithm fulfils the needs of this. [2]
The primary goal of lightweight cryptography algorithm is to give high security for gadgets with constrained assets. These gadgets with constrained assets deploy lightweight ciphers that are genuine and need less power consumption and less computation. The lightweight cipher is developed with quick encryption rate and little utilization of assets. While designing of lightweight cryptographic algorithm, it is a tradeoff among performance and assets needed for a provided security level. The word Performance is described as power and energy consumption, latency and output. 
This algorithm is deployed in lesser costs and for little energy consumption in comparison to old cryptography algorithms that supposed to have different apps such as medical assets and on-vehicle gadgets. It is frequently difficult for experts without mastery to misuse this innovation by picking a legitimate lightweight cryptographic algorithm and trying it with proper awareness. 
The lesser price, lesser energy consumption, lightweight cryptographic methodology is used in gadgets that consist of on-vehicle device and healthcare assets. This will be supposed to become best security techniques that are helpful for producing next-gen network services like IoT ,smart grid and the cyber-physical model.  [1]
The potential security threats in systems using low-power devices
There is important role played by security in every area. Most of present day cryptographic algorithms would build for desktop/server conditions, huge numbers of these algorithms are not executed in the low-power gadgets utilized in applications, for example, “automotive frameworks, wireless sensor networks, medical assets,  IoT (the Internet of Things), cyber-physical models, and the smart grid.”
There are various security threats in low-power device such as the Internet of Things (IoT). An IoT framework is vulnerable physically, or vulnerable from inside its system or from software’s on the framework, and in conclusion from threats on encryption schemes. IoT is deployed utilizing various available system advances such as RFIDs, Wireless Sensor Networks, distributed control system, Internet and so forth. However, there is a need for a right listing of the threats with the final objective that it typifies the most of the innovative type of dangers, so better protective measures can be produced and actualized for protecting it. Below table shows different security threats or attacks in low-power device: [5]
The working mechanism of lightweight cryptography
S Box (Substitution Box): For lightweight cryptography block ciphers, input data to box s is structure that is basically four bits block that outcome into four bits result from interchange function.
Rounds: The Encryption and decryption algorithm in lightweight cryptography does calculations in different rounds. In every round, there are various subkeys to be used. All these subkeys are created by utilizing key generation algorithm.
