An overview of public key cryptography

Lecture 6: Overview of Public-Key Cryptography and RSA

In this lecture, we give an overview to the public-key cryptography, which is also referred to as asymmetric cryptography. We will first introduce the background of public-key cryptography. Then we will study the model of public-key cryptosystem, and the requirement to design a practical public-key algorithm. Finally, we will study the design of RSA algorithm. The concept of public-key (asymmet...

Cryptography. key exchange, public key

General cryptographic schemes are presented where keys can be one-time or ephemeral. Processes for key exchange are derived. Public key cryptographic schemes based on the new systems are established. Authentication and signature schemes are easy to implement. The schemes may be integrated with error-correcting coding schemes so that encryption/coding and decryption/decoding may be done simultan...

An Algebraic Method for Public-key Cryptography

Algebraic key establishment protocols based on the difficulty of solving equations over algebraic structures are described as a theoretical basis for constructing public–key cryptosystems.

Public Key Cryptography

2 Public-key Cryptography

Secure transmission of private information is a crucial issue in today’s highly computerized world. Cryptographic algorithms are used to provide privacy of message transmission and to certify authenticity of sender and/or receiver of a message and message integrity as well as undeniability of transmitted messages (Menezes et al., 1996). The message that is sent by the sender is called the plain...
