1. A method for controlling an engine having a control module and smart nodes comprising: (10) (7)

maintaining a block chain ledger at the control module of the aircraft engine, wherein the block chain comprises an information block from at least a preceding engine start;

maintaining a hash of at least a digital certificate and data at one of the smart nodes;

transmitting a message including the hash to the control module;

receiving the message at the control module;

at the control module determining a control hash based upon the information from at least a preceding engine start;

at the control module comparing the hash to the control hash;

based upon the comparison, starting the engine and updating the block chain ledger as a function of the received message.

2. The method of claim 1, further comprising maintaining a second hash of at least the digital certificate and data at another of the smart nodes; wherein the message includes the second hash; (0) (1)

3. The method of claim 1, wherein the step of transmitting the message also includes encrypting the message with one of a private key or public key. (0)

4. The method of claim 1, wherein the step of receiving the message also comprises decrypting the message with one of a private key or public key. (0)

5. The method of claim 1, further comprising at the one of the smart nodes maintaining a local block chain ledger, wherein the local block chain comprises a digital certificate and data from at least the preceding engine start and wherein the step of transmitting further comprises updating the local block chain ledger. (1) (0)

6. The method of claim 1, wherein the data is selected from the group consisting of manufacturer, serial number of the smart node, software configuration, date of manufacture, date of qualification, public key and a preceding hash. (0)

8. The method of claim 1, further comprising updating the digital certificate. (1) (0)

10. The method of claim 1, wherein the step of determining a control hash further comprises updating the block chain ledger with a digital certificate and data associated with the one smart node prior to the comparison. (1) (0)

12. The method of claim 1, wherein the control module and smart nodes are arranged in a DCS architecture. (0)

13. The method of claim 1, wherein the control module and smart nodes are arranged in a CCS architecture. (0)

14. The method of claim 1, wherein the control module maintains block chain ledgers for each of the smart nodes. (0)

15. A method of authentication of a smart node in a gas turbine engine, comprising: (2) (7)

determining the required operational characteristics for the smart node;

generating a hash at a control module reflective of required operational characteristics for the smart node;

storing the hash in a block chain;

receiving a second hash at the control module from the smart node;

comparing the hash in the block chain with the second hash;

authenticating the operation of the smart node based upon the comparison; and,

updating the block chain with the second hash.

16. The method of claim 15, further comprising generating the second hash at the smart node as at least a reflection of operations characteristics of the smart node. (2) (0)

18. The method of claim 15, further comprising starting a gas turbine subsequent to the authentication of the smart node. (0)

20. A method for authenticating a component on a gas turbine prior to operation, comprising: (0) (7)

maintaining a block chain ledger at a control module of the gas turbine, wherein the block chain comprises successive information blocks;

wherein the information blocks include information reflective of at least the component;

receiving a message at the control module from the component;

at the control module determining a control hash based upon the information reflective of at least the component;

determining a hash based at least upon the received message and at the control module comparing the hash to the control hash;

based upon the comparison, authenticating the component, updating the block chain ledger as a function of the receive message; and,

operating the gas turbine.
