The Field of Cryptography

Cryptography is the study of how to make data private or secure. It is an important branch of mathematics, and many aspects of it are included in computer science. The field of cryptography also uses aspects of information theory, computational complexity, statistics, combinatorics, number theory, and other fields. It is a branch of engineering and is used to secure information. The secret to its success lies in the ability to secure both the transmission and storage of sensitive data.

Cryptography can also be used for storing and transmitting confidential information. It is one of the key components of digital rights management, a set of techniques used to control copyrighted material. The Digital Millennium Copyright Act was signed by President Bill Clinton in 1998, which criminalized the use of some cryptanalytic techniques and technologies. As of 2016, this law only applies to the U.S., not the European Union. As of today, it is possible to protect personal data through the use of deterministic algorithms.

In the past, cryptography was associated with encryption. It is the process of converting information into incomprehensible nonsense. The sender of an encrypted message will share the secret to decode the message with the intended recipient and with adversaries. In the literature, these two parties are often referred to as Alice and Bob. However, since the rise of cheap computers, the field of cryptography has become more complex and varied. This has led to a wide variety of uses and controversial legal issues.
