There is some interest in encryption schemes meant for humans to perform without computational aid. (Relevant questions here, here, and here.) People often cite the VIC pen-and-paper cipher, the Schneier Solitaire cipher, or more recently the LC4 cipher. These would be useful in the context of, say, two people using communication devices where one or both may be monitored.
I've seen these referred to as pen-and-paper ciphers, human-computable ciphers, and as low-tech ciphers. They've also been compared to historical ciphers.
I could not find any lit-reviews for these schemes. Generally, I'm wondering if this is a field, and how much it has been explored. More specifically, is there a name for this class of modern, strong, human-computable encryption schemes? Have there been any attempts at defining, describing or measuring what makes a cipher "human computable"?
