Abstract
Methods for a server include defining a starting element and an element step size. A pad mapping is applied to a data Random Cipher Pad (RCP) to obtain a Key RCP using each element of the Data RCP once in a predetermined non-sequential order. The starting element and the element step size are combined with the Data RCP. The Data RCP is encrypted using the Key RCP to produce a subsequent Data RCP. The subsequent Data RCP is transmitted to another computer. Methods for clients include applying a pad mapping to a Data RCP to obtain a Key RCP using each element of the Data RCP once in a predetermined non-sequential order to develop the Key RCP. The Key RCP is encrypted using the Data RCP to produce a subsequent Key RCP. A data structure is encrypted using the Data RCP to produce an encrypted data structure.
