SmokeStack is a Personal Chat Server - an Android Echo Server Application for the Chat Messenger Smoke which is known as worldwide the first mobile McEliece Messenger (McEliece, Fujisaka and Pointcheval). This Volume II is about the Chat Server SmokeStack. Volume I of the same author is about the referring Smoke Chat Messenger Client. This Open Source Technical Website Reference Documentation on paper addresses to students, teachers, and developers to create a Personal Chat Server on Android based on Java for learning and teaching purposes. The book introduces into TCP over Echo (TCPE), Cr. Discovery, FF Keys, an Argon2id key-derivation function, the Steam file transfer protocol and the Juggling Juggernaut Protocol for Juggernaut Keys, mobile Server Technologies, Ozone Postboxes and further topics.

Based on the historical development of so-called Crypto Chips, the current Transformation of Cryptography shows numerous changes, innovations and new process designs in the field of Cryptography, which also need to be integrated in a hardware design of Microprocessors and Microcontrollers for a Secure Embedded System. Using the example of the encrypting Echo protocol, a design of a hardware architecture based on three Chips is presented: The central Echo Chip #1 represents a "Trusted Execution Environment" (TEE), which is not connected to the Internet for the conversion processes from plain text to cipher text and is supposed to remain quasi original, to prevent software injections or possible uploads of copies of the plain text. The technical specifications of all three microprocessors are described in detail. The established paradigm of separation is recognized as a security feature and discussed as a perception for a Next Generation of Microcontrollers in the field of Mobile Messaging under the technical term "Going the Extra Mile". This security architecture is then discussed in the context of seven different current risk cases with the consolidated result that the well-known OSI (Open Systems Interconnection) Model is expanded to the Secure Architecture Model, abbreviated SAM.
The global crisis of Privacy in the 21st century also includes discussions about the right to encryption and restrictions on so-called end-to-end encryption. In order to communicate confidentially and secure against eavesdropping, simple and practical encryption is required for everyone. But how can it be available to everyone? The magic of replacing legible characters with other apparently random and therefore illegible characters had been almost religious for centuries: only those initiated into the invention of a secret language could crack the messages. Encryption remained Super Secreto - Top Secret - Streng Geheim! In the age of smartphone and pocket computers, it is now available to everyone: ever more sophisticated math calculates the so-called cipher text with corresponding keys in our messengers. Both keys and encrypted text used to have to be transmitted to the recipient. In today's Epoch of Cryptography, the transmission of the keys is no longer necessary: The risky transport route for the keys can even be omitted! From the fascination of how Cryptography became abstinent in the transmission of keys - what effect it has on the desire of state agencies for secondary keys - and how multiple and exponential encryption makes resistant against the decryption-attempts of super-quantum-computers ... ... tells Theo Tenzer in this exciting political, technical and socially relevant innovation and science portrait on the Third Epoch of Cryptography.
In their book "Era of Exponential Encryption - Beyond Cryptographic Routing" the authors provide a vision that can demonstrate an increasing multiplication of options for encryption and decryption processes: Similar to a grain of rice that doubles exponentially in every field of a chessboard, more and more newer concepts and programming in the area of cryptography increase these manifolds: both, encryption and decryption, require more session-related and multiple keys, so that numerous options even exist for configuring hybrid encryption: with different keys and algorithms, symmetric and asymmetrical methods, or even modern multiple encryption, with that ciphertext is converted again and again to ciphertext. It will be analyzed how a handful of newer applications like e.g. Spot-On and GoldBug E-Mail Client & Crypto Chat Messenger and other open source software programming implement these encryption mechanisms. Renewing a key several times - within the dedicated session with "cryptographic calling" - has forwarded the term of "perfect forward secrecy" to "instant perfect forward secrecy" (IPFS). But even more: if in advance a bunch of keys is sent, a decoding of a message has to consider not only one present session key, but over dozens of keys are sent - prior before the message arrives. The new paradigm of IPFS has already turned into the newer concept of these Fiasco Keys. Fiasco Keys are keys, which provide over a dozen possible ephemeral keys within one session and define Fiasco Forwarding, the approach which complements and follows IPFS. And further: by adding routing- and graph-theory to the encryption process, which is a constant part of the so called Echo Protocol, an encrypted packet might take different graphs and routes within the network. This shifts the current status to a new age: The Era of Exponential Encryption, so the vision and description of the authors. If routing does not require destination information but is replaced by cryptographic insights, then it is "beyond cryptographic routing". "Cryptographic Discovery" means: If the cryptographic token is matching, the message belongs to me. The Echo Protocol is in this regard an initial welcome within the Era of Exponential Encryption. The authors identify also four arms within the Era of Exponential Encryption and derive from these developments social, legal, political and economic recommendations.
Das vorliegende Buch bietet eine Übersicht an quell-offenen Software-Programmen und -Projekten zur Verschlüsselung. Sie sind zentral, um Bürger:innen einen Schutz vor Überwachung sowie eine Perspektive zur Absicherung des Briefgeheimnisses und ihrer Privatheit zu ermöglichen. Mit diesem Band "Open-Source Verschlüsselung - Quell-offene Software zur Demokratisierung von Kryptographie: Schutz vor Überwachung" legt der Verein Aktion Freiheit statt Angst e.V.
