One-Time Pad The most famous primitive which provides information-theoretic security is the one-time pad. Here, a binary message m ∈ {0,1}t is encrypted by taking a key k ∈ {0,1}t uniformly at random, and then producing the ciphertext c= m⊕k. In terms of our earlier security models, this is an IND-PASS scheme even in the ...
