Perfect Secrecy other than One-time Pad
There is a famous result about perfect secrecy, usually called Shannon's theorem:
If an encryption scheme has perfect secrecy, then $|\mathcal{K}| \ge |\mathcal{M}|$, where $\mathcal{K}$ is the set ...

Perfect Secrecy other than One-time Pad
There's computational perfect secrecy and information-theoretic perfect secrecy, and OTP belongs to the latter.
If it's well-known information-theoretic perfect secrecy that you seek and is no less ...

How were one-time pads and keys historically generated?
This procedure, though not entirely random theoretically, did serve as one-time pad generator.
At the exhibition, besides many interesting encryption machines, a
copy of the book “Achtung Spione” was ...
