The Self-Anti-Censorship Nature of Encryption: On the Prevalence of Anamorphic Cryptography

As part of the responses to ongoing crypto wars, notion Anamorphic Encryption was put forth. The allows private communication in spite a dictator who is engaged an extreme form surveillance and or censorship, where it asks for all keys knows may even dictate messages. original work pointed out efficient ways use two known schemes anamorphic mode, bypassing draconian censorship hiding information from all-powerful dictator. A question left open whether these examples are outlier results mode pervasive existing systems. Here we answer above question: develop new techniques, expand notion, show that Cryptography is, fact, very much prevalent. We first refine with respect nature covert communication. Specifically, distinguish Single-Receiver many one communication, Multiple-Receiver within group conspiring users. then can be embedded randomness used encryption, give families constructions applied numerous ciphers. In total cover classical encryption schemes, some which actual use. Among our channel higher capacity than regular channel. sum, shows large extent potential futility control over strong by (typical stronger governments engaging crypto-wars): While such limitations obviously hurt utility typically brings safety computing systems, they essentially, not helping implications what here means practice require further policy legal analyses perspectives, technical aspects regarding issues clearly showing war against Cryptography.
