Cryptography in fiction refers to the use of codes, ciphers, and other techniques for secure communication as a plot device or thematic element in literary works. In many stories, cryptography plays a key role in mystery, espionage, adventure, or science fiction narratives. It allows authors to create tension, build intrigue, and challenge characters in their quest to decipher hidden messages or protect sensitive information.
The Communication Theory of Secrecy Systems, primarily discussed by Claude Shannon in his foundational work on cryptography and information theory, provides a systematic approach to understanding how information can be securely transmitted over insecure channels. The key elements of this theory include the following: 1. **Information and Uncertainty**: At the core of the theory is the concept of information as a measure of uncertainty. Shannon introduced the idea of quantifying information using bits and entropy, which measures the unpredictability of information.
CAdES, which stands for CMS Advanced Electronic Signatures, is a standard for digital signatures that extends the Cryptographic Message Syntax (CMS) to provide advanced features for electronic signatures. It is defined under various specifications from the European Telecommunications Standards Institute (ETSI) and is particularly recognized in the context of eIDAS (the Electronic Identification and Trust Services Regulation) in the European Union.
PKCS #8 (Public Key Cryptography Standards #8) is a standard that specifies a syntax for storing private key information in a platform-independent way. It is part of a set of standards developed by RSA Laboratories to facilitate secure communications and cryptographic operations.

Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.Figure 1. Screenshot of the "Derivative" topic page.
