Abstract
Methods for the storage and retrieval of a digital file are disclosed. The file is encrypted with a random binary key. A mathematical challenge-response-pair (CRP} mechanism is used to generate an ordered list of responses from a list of challenges. A subset of responses within the ordered list of responses is selected, which each selected response occupying a position in the ordered list that is the same position as a first binary symbol in the random key. In this way, the key can be encoded in the selection of responses. To recover the key, the selected responses are compared to a full list of responses to determine which of the responses in the full list match selected responses. Matches indicate the first binary symbol in the corresponding position in the key and non-matches indicate the second binary symbol. In this way, the key is reconstructed, and file may be decrypted.
