1. A method of encrypting information, comprising:

  • defining a plaintext message to be encrypted;

    defining a subset of the plaintext message comprising a plurality of digital information elements of the plaintext message having a pseudorandom order defined by an algorithm;

    constructing a keystream using at least one automated processor with an initialization vector formed from the defined subset, wherein the initialization vector is not constrained to a predetermined length;

    encrypting a residual portion of the plaintext remaining after separation of the defined subset from the residual portion, with the keystream into a ciphertext using at least one automated processor; and

    storing the defined subset at a location, communicated through a communication network, remote from the encrypted residual portion of the plaintext, such that for at least one time period, the defined subset and the encrypted residual portion of the plaintext are stored remotely from each other with respect to the communication network.
