Method and process for securing an executable image

A method for securely loading software into secured memory via multiple security modules, comprising:

• dividing the software into n images;
• generating n control hashes, each control hash a function of the nth image and the n−1 image;
• recording each of the n control hashes in a distributed ledger;
• storing each of the n images in a corresponding n security modules;
• loading a corresponding image of the n images from an ith security module of the n security modules into the secured memory, where i is less than or equal to n;
• generating an ith hash as a function of the ith image stored in the ith security module and the i−1 image stored in the i−1 security module;
• comparing the ith hash to the corresponding ith one of the corresponding n control hashes;
• and
• executing the loaded software from the secured memory based upon the comparison.

A non-transitory, computer-readable storage medium comprising executable instructions that, when executed by one or more processors, cause the one or more processors to:

• divide a software image into n images;
• generate n control hashes, each control hash a function of the nth image and the n−1 image;
• record each of the n control hashes;
• store each of the n images in a corresponding n security modules;
• load the corresponding image of the n images from an ith security module of the n security modules into secured memory, where i is less than or equal to n;
• generate an ith hash as a function of the ith image stored in the ith security module and the i−1 image stored in the i−1 security module;
• compare the ith hash to the corresponding ith one of the corresponding n control hashes;
• and
• execute the loaded software from the secured memory based upon the comparison.
