EFFICIENT KEY MANAGEMENT IN DISTRIBUTED APPLICATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 18479601 titled 'EFFICIENT KEY MANAGEMENT IN DISTRIBUTED APPLICATION

Simplified Explanation

The apparatus described in the patent application facilitates efficient key refresh in a node within a distributed system. Here are the key points of the innovation:

  • The apparatus can determine a collective operation initiated by the node.
  • It can generate a new key based on a previous key maintained at the apparatus.
  • The new and previous keys are used for encrypting and decrypting inter-node packets in the distributed system.
  • The apparatus maintains the keys for the duration of the collective operation and discards the previous key at a threshold point.

        1. Unanswered Questions
      1. How does the apparatus handle key synchronization among nodes in the distributed system?

The patent abstract does not provide details on how the apparatus ensures all nodes have the updated key during the collective operation.

      1. What encryption algorithms are compatible with the key refresh mechanism described in the patent application?

The abstract does not specify the encryption algorithms or protocols used for generating and maintaining keys in the apparatus.


Original Abstract Submitted

An apparatus facilitating efficient key refresh in a node is provided. During operation, the apparatus can determine a collective operation initiated by the node. The node can include a processor and can be in a distributed system comprising a plurality of nodes. The collective operation can be performed by a subset of the plurality of nodes in conjunction with each other. The apparatus can generate a new key based on a previous key maintained at the apparatus. Here, a respective key can be used for encrypting an inter-node packet in the distributed system. The apparatus can maintain the new and previous keys for the duration of the collective operation. Either of the new and previous keys can be used for decrypting messages received at the apparatus from other nodes of the distributed system. Upon determining a threshold point of the collective operation, the apparatus can discard the previous key.
