Welcome to the second book from RSA Press, RSA Security’s Official Guide to Cryptography! As the Internet becomes a more pervasive part of daily life, the need for e-security becomes even more critical. Any organization engaged in online activity must assess and manage the e-security risks associated with this activity. Effective use of cryptographic techniques is at the core of many of these risk-management strategies.

The development of public-key cryptography is the greatest and perhaps the only true revolution in the entire history of cryptography. From its earliest beginnings to modern times, virtually all cryptographic systems have been based on the elementary tools of substitution and permutation, and can be classed as private/secret/single key (symmetric) systems. All classical, and modern block and stream ciphers are of this form.

The Elliptic Curve Cryptography (ECC) is evolving as an important cryptography, and shows a promise to be an alternative of RSA. Small size, high security and other features characterize ECC. Based on the theory of ECC, this paper analyzes its advantages over other cryptographies and focuses on its principle.
