Abstract: A system includes processor(s) and memory(s). When encryption key(s) need to be generated to encrypt a key, processor(s): generate encryption key(s); encrypt key using encryption key(s) to generate encrypted key; split encrypted key and encryption key(s) into set(s) of key components, wherein subset of key components can be used to reconstruct encrypted key and encryption key(s); and erase key from memory(s). When encryption key(s) need to be used, processor(s): receive set(s) of key components from subset(s) of users that can be used to reconstruct encrypted key and encryption key(s) used to decrypt key from encrypted key; when set(s) of key components is received from subset(s) of users that can be used to reconstruct encrypted key and encrypted key(s), reconstruct encrypted key and encryption key(s); and when the encrypted key and the encryption key(s) have both been reconstructed, decrypt encrypted key into key using encryption key(s).

Abstract: Disclosed is a sensor for monitoring a composite structure. The sensor includes multiple sensing elements of different sizes, each configured for different respective monitoring tasks. Also disclosed are methods of fabricating the sensor, designing and manufacturing the sensor, and attaching the sensor to the composite structure.

Abstract: A system includes at least one processor and at least one memory communicatively coupled to the at least one processor. The at least one processor is configured to receive a plurality of doubly-encrypted secret parts that were encrypted using at least a public key belonging to a public/private keypair. The at least one processor is also configured to decrypt each of the plurality of doubly-encrypted secret parts into a corresponding singly-encrypted secret part using a private key belonging to the public/private keypair. The at least one processor is also configured to decrypt each corresponding singly-encrypted secret part into a corresponding secret part. A secret is reconstructed from a quantity of corresponding secret parts that is a subset of a total number of secret parts. The public key, the private key, or both are rotated by creating a new version of the public key, the private key, or both.

Abstract: A system includes processor(s) and at least one memory communicatively coupled to the processor(s). The processor(s) is/are configured to encrypt at least one set of asset encryption key parts into at least one set of encrypted asset encryption key parts using at least one symmetric key or at least one public key, each public key belonging to a corresponding one of at least one public/private keypair. At least a subset of the at least one set of asset encryption key parts are used to reconstruct the asset encryption key, which is used to perform an action using at least one asset key. The processor(s) is/are also configured to encrypt the encrypted asset encryption key parts and corresponding metadata using a public key of a public/private keypair so the at least one set of encrypted asset encryption key parts is doubly-encrypted.
