1. A method, comprising:
- generating, by a first line-replaceable unit (LRU) in a plurality of LRUs, a first encryption key;
encrypting specified data using the first encryption key, wherein the specified data is stored as backup data in a storage media device attachable to the first LRU;
generating, based on key data of at least a second LRU in the plurality of LRUs, a second encryption key; and
encrypting the first encryption key using the second encryption key.

Abstract
Techniques are disclosed for securing backup operational data (e.g., of an aircraft) maintained by a line-replaceable unit (LRU) in a removable storage media device. The LRU generates a first encryption key. The LRU encrypts the operational data using the first encryption key. The LRU generates a second encryption key based on key data of at least a second LRU. The LRU encrypts the first encryption key using the second encryption key.
