摘要
In one exemplary embodiment, a method includes: storing a key on a storage medium of a first apparatus, where a value of the key varies over time, where the key is configured to enable decryption of encrypted information; and sending a plurality of communications from the first apparatus to a second apparatus, where each communication comprises at least one portion of the key, where no single communication comprises an entirety of the key. In further exemplary embodiments, the encrypted information is encrypted in accordance with a threshold-based encryption scheme having a threshold such that the encrypted information is configured to be decrypted only if a decryptor is in possession of sufficient accurate portions of the key as compared to the threshold.
