Systems and methods for securing data in motion
View Patent ↗Two approaches are provided for distributing trust among certificate authorities. Each approach may be used to secure data in motion. One approach provides methods and systems in which a secure data parser is used to distribute trust in a set of certificate authorities during initial negotiation (e.g., the key establishment phase) of a connection between two devices. Another approach of the present invention provides methods and systems in which the secure data parser is used to disperse packets of data into shares. A set of tunnels is established within a communication channel using a set of certificate authorities, keys developed during the establishment of the tunnels are used to encrypt shares of data for each of the tunnels, and the shares of data are transmitted through each of the tunnels. Accordingly, trust is distributed among a set of certificate authorities in the structure of the communication channel itself.
