WebCryptography is the mathematical foundation on which one builds secure systems. It studies ways of securely storing, transmitting, and processing information. Understanding what cryptographic primitives can do, and how they can be composed together, is necessary to build secure systems, but not su cient. Webexample, variations of factoring and modular exponentiation (with inverse being the discrete logarithm problem) are all plausible one-way functions. It turns out that one-way functions …
