What is a cryptography system?

Cryptography refers to the techniques and algorithms that are used today for secure communication and data in storage. It incorporates mathematics, computer science, electronics and digital signal processing. Broadly speaking, there are four types of cryptography systems:

What is lightweight cryptography?

Lightweight cryptography is used in applications and technologies that are constrained in computational complexity: limiting factors can be memory, power and computing resources. The need for lightweight cryptography is expanding in our modern digital world.

When did cryptography start?

Extensive open academic research into cryptography is relatively recent, beginning in the mid-1970s. In the early 1970s IBMpersonnel designed the Data Encryption Standard (DES) algorithm that became the first federal government cryptography standard in the United States.

What are the security goals of cryptography?

As security has advanced, the field of cryptography has expanded to include a broader range of security goals. These include message authentication, data integrity, secure computation, and more. Cryptography is at the foundation of the modern society.
