WebSep 29, 2024 · One Time Pad (OTP) requires uniform random key bits to be information-theoretically secure. Once the key is transmitted securely with a trusted carrier, than the messages transmitted between the two sides are secure as long as the keystream is never used again ( keywords: two-time pad, many-time pad, and crib-dragging). WebAug 19, 2014 · c := E (k,m) = m XOR G (K) In this case, c is the cipher text, m is the plain text, the k is the key, and the G is a Pseudo Random Generator to generate a pad that has the equal length with m. This cipher is safe when using only one-time, but is not safe when using many-time.
