Extracted text: 2. Describe the flaw in this argument: Consider the following attack against one-time pad: upon seeing a ciphertext c, the eavesdropper tries every candidate key k e {0,1}^ until she has found the one that was used, at which point she outputs the plaintext m. This contra- dicts the argument in the book that the eavesdropper can obtain no information about m by seeing the ciphertext.
