Executable command security

A method of using an executable command, the method comprising

• transferring, by processing circuitry, transferring individual code segments of the executable command and storage instructions to memory circuitry, wherein the storage instructions direct the memory circuitry to store individual code segments of the executable command in different isolated memories, wherein the individual code segments comprise portions of the executable command and the different isolated memories isolate the individual code segments from each other;
• receiving, by the memory circuitry, receiving the individual code segments of the executable command and the storage instructions, and in response, storing the individual code segments of the executable command in the different isolated memories;
• identifying, by the processing circuitry, identifying individual digital certificates for the individual code segments and validating the individual digital certificates for the individual code segments with individual cryptographic keys for the individual code segments, and in response, transferring retrieval instructions to the memory circuitry, wherein the retrieval instructions direct the memory circuitry to transfer the individual code segments of the executable command from the different isolated memories, and wherein the individual digital certificates for the individual code segments comprise individual data strings that are encrypted with individual private keys for the individual code segments and the individual cryptographic keys for the individual code segments comprise individual public keys for the individual code segments;
• receiving, by the memory circuitry, receiving the retrieval instructions from the processing circuitry, and in response, transferring the individual code segments of the executable command from the different isolated memories to the processing circuitry;
• receiving, by the processing circuitry, receiving the individual code segments of the executable command from the memory circuitry and assembling the executable command from the received individual code segments;
• and
• executing, by the processing circuitry, executing the assembled executable command, wherein executing the assembled executable command comprises accessing digital content.

A user communication device to process an executable command, the user communication device comprising:

• processing circuitry configured to transfer individual code segments of the executable command and storage instructions to memory circuitry, wherein the storage instructions direct the memory circuitry to store individual code segments of the executable command in different isolated memories, wherein the individual code segments comprise portions of the executable command and the different isolated memories isolate the individual code segments from each other;
• the memory circuitry configured to receive the individual code segments of the executable command and the storage instructions, and in response, store the individual code segments of the executable command in the different isolated memories;
• the processing circuitry further configured to identify individual digital certificates for the individual code segments and validate the individual digital certificates for the individual code segments with individual cryptographic keys for the individual code segments, and in response, to transfer retrieval instructions to the memory circuitry, wherein the retrieval instructions direct the memory circuitry to transfer the individual code segments of the executable command from the different isolated memories, and wherein the individual digital certificates for the individual code segments comprise individual data strings that are encrypted with individual private keys for the individual code segments and the individual cryptographic keys for the individual code segments comprise individual public keys for the individual code segments;
• the memory circuitry further configured to receive the retrieval instructions from the processing circuitry, and in response, transfer the individual code segments of the executable command from the different isolated memories to the processing circuitry;
• the processing circuitry further configured to receive the individual code segments of the executable command from the memory circuitry and assemble the executable command from the received individual code segments;
• and
• the processing circuitry further configured to execute the assembled executable command, wherein the assembled executable command is to access digital content.
