Secure information distribution between nodes (network devices)

摘要

In an embodiment, a method of secure information distribution between nodes, includes: performing a handshake process with an adjacent node to determine membership in a secure group; and distributing secure information to the adjacent node, if the adjacent node is a member of the secure group. In another embodiment, an apparatus for secure information distribution between nodes, includes: a node configured to performing a handshake process with an adjacent node to determine membership in a secure group, and distribute secure information to the adjacent node, if the adjacent node is a member of the secure group.

1. A method of secure information distribution with an adjacent network device, the method comprising:
providing, by a first network device, a component value A1 to the adjacent network device; receiving, by the first network device, a component value B1 from the adjacent network device; performing, by the first network device, a handshake process with the adjacent network device to determine membership of the adjacent network device in a secure group, wherein the handshake process comprises calculating a value by applying the component values A1 and B1, and a key value associated with the secure group, to a one-way function f(x), wherein the key value is obtained prior to the handshake process; distributing secure information to the adjacent network device if a determination is made from the calculated value that the adjacent network device is a member of the secure group; and allowing for construction of the secure group by transmitting a burst of NB handshakes for every amount of time TB, where NB is a number of handshakes and TB is a time amount between burst of handshakes.
