Would this be an appropriate reference (though also a dicdef, and slightly obscure to non-computer experts)? Jackiespeel (talk) 10:49, 1 March 2020 (UTC)
The article states that: "Cover coding is secure if the tag signal can't be intercepted and the random number is not re-used.".
This is only true if the random number is just as long as the message being sent. Otherwise you are effectively re-using a one-time pad.
If you know the random number length of N, it is possible to know the XOR value of two bits that are length N apart.
In general all attacks that apply to re-using a one-time pad also apply here. — Preceding unsigned comment added by Rocqua (talk • contribs) 15:02, 9 June 2022 (UTC)
