Question
Case Project 3-3
Lightweight Cryptography Due to the importance of incorporating cryptography in low-power devices, a new “subfield” of cryptography is being developed called lightweight cryptography. This has the goal of providing cryptographic solutions that are uniquely tailored for low-power devices that need to manage resource vs. security constraints. Research lightweight cryptography. What are its goals? How will it work? Who is behind it? Will it be standardized? When will it appear? Write a one-page paper on your findings.
Explanation / Answer
Lightweight Cryptography:
Cryptography is the combination process of encryption and decryption. That is, Cryptography is a process in which an ordinary plain text information is converted into unintelligible text or cypher text and then back to the plain text. Lightweight Cryptography is almost the same thing but with a consideration of lightweight and security. Lightweight Cryptography helps to reach high levels of security using only a small computing power. The definition for Lightweight Cryptography on Internet is - Lightweight cryptography is a cryptographic algorithm or protocol tailored for implementation in constrained environments including RFID tags, sensors, contactless smart cards, health-care devices and so on.
The goal of lightweight cryptography is to enable a diverse range of modern applications. The modern applications like the smart meters, vehicle security systems, wireless patient monitoring systems, Intelligent Transport Systems (ITS) and the Internet of Things. The Lightweight Cryptography helps a very wide variety of devices. It can be implemented on a wide range of hardware and software. It's communication can be wired or wireless. Wireless devices are powered either by electromagnetic induction or by a battery. The battery can be disposable or rechargeable. For some applications, the energy or power consumption is important. But for other applications a low latency is more important. The limiting factor can be that hardware area or software code size is small or that only a small amount of RAM is available.
The Lightweight cryptography works with the help of various features. They can be the block ciphers, stream ciphers, hash functions and so on. Lightweight cryptography contributes to the security of various smart objects networks because of its efficiency and smaller footprint. The lightweight primitives should be be implemented in the networks.
Lightweight cryptography is mainly used in the Internet of things. The Internet of things faces a number of challenges like security, privacy, power, bandwidth, scalability and heterogeneity. The two reasons that support lightweight cryptography are: Efficiency of end-to-end communication and Applicability to lower resource devices.
The lightweight cryptography will be standardized so that the public can access all the benefits of lightweight cryptography. The lightweight cryptography has been already a hot topic of discussion. It has already appeared for the first round of standardization.
