In this chapter we will discuss public-key cryptography(PKC) and it’s various applications and its probable use. Limitations and disadvantages of symmetric-key cryptography(private-key cryptography) motivates the extensive use of public-key cryptography. Well known limitations are: Key exchange is a major problem in symmetric key cryptography. you

In this chapter, we will explore some computational aspects of modular arithmetic, which we studied in Chapter 6. We will be concerned about how to compute certain numbers in a most efficient way. There is a whole field at work here, of which we barely scratch the surface, called computational complexity.

The basic idea of public-key cryptography are public keys. Each person’s key is separated into two parts: a public key for encryption available to everyone and a secret key for decryption which is kept secret by the owner. In this chapter we introduce the concept of public-key cryptography.

Non-secret encryption Until relatively recently cryptosystems were always symmetric. They relied on the use of a shared secret key known to both sender and receiver. This all changed in the 1970s. Public key cryptosystems, as they are now called, revolutionised the theory and practice of cryptography by relying for their impenetrability on the ...

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).

This chapter presents an asymmetric approach to cryptography – it uses different keys for encryption and decryption. The key for encryption is announced publically so that everybody can encode a message. Only the owner of the matching secret key can decode the encrypted message.

Introduction to Public-Key Cryptography
2005In this chapter we introduce the basic building blocks for cryptography based on the discrete logarithm problem that will constitute the main motivation for considering the groups studied in this book. We also briefly introduce the RSA cryptosystem as for use in practice it is still an important public-key cryptosystem.
