How were codes in WW1 reciphered (to enhance security levels) without them turning meaningless?

The concept is called superencipherment or multiple encryption, and works as follows: The original message M is enciphered using the code book, resulting in an enciphered message C1. C1 is then ...

How were codes in WW1 reciphered (to enhance security levels) without them turning meaningless?

Anyone could be confused by this, especially by the part about the Zimmermann telegram. Codebooks come in three flavors: one-part, two-part, and hybrid. You described a one-part codebook. These are ...

How do encrypted radios perform key exchange?

P25 AFAIK does not include a radio to radio key exchange protocol. Keys are loaded onto the radio by a key fill device or over the air rekeying which relies on a long term per device key protects the ...
