To incorporate cryptography in low-power devices, a new subfield of cryptography called lightweight cryptography is being developed. Research lightweight cryptography. What are its goals? How will it work? Who is behind it? Will it be standardized?

Answer 1

Lightweight cryptography is a subfield of cryptography that focuses on developing efficient and secure cryptographic algorithms that are specifically designed for use in resource-constrained environments, such as low-power devices like sensors, RFID tags, and IoT devices. The goals of lightweight cryptography include reducing computational complexity, minimizing memory requirements, and optimizing power consumption while still maintaining a high level of security.

These algorithms typically use less memory and computational resources compared to traditional cryptographic algorithms like AES or RSA, making them more suitable for implementation in low-power devices with limited processing capabilities. Lightweight cryptographic algorithms often rely on simpler and more efficient designs, such as lightweight block ciphers and hash functions, to achieve a balance between security and efficiency.

Various research institutions, universities, and industry partners are actively involved in the development of lightweight cryptography. Some of the prominent researchers and organizations working in this field include the National Institute of Standards and Technology (NIST), the European Telecommunications Standards Institute (ETSI), and the Cryptanalysis and Security group at Ruhr University Bochum.

As lightweight cryptography continues to gain momentum, efforts are being made to standardize lightweight cryptographic algorithms to ensure interoperability and security across different platforms and devices. Standardization bodies like NIST and ETSI are actively involved in the evaluation and selection of lightweight cryptographic algorithms for potential inclusion in industry standards. This standardization process is crucial for promoting the widespread adoption of lightweight cryptography and ensuring the security of low-power devices in the IoT ecosystem.
