Secure communications using organically derived synchronized processes

A system with secure communication within a security group having a first plurality of nodes, the system comprising:

• a first node of the security group, each node of the security group having a synchronized data set, the synchronized data set having at least a first seed, the first node being configured to
• store a parameter data set containing a plurality of values;
• select, using the first seed value, one or more of the plurality of values in the parameter data set to form a first parameter subset;
• generate a first cipher key using the first parameter subset at the first node;
• encrypt user data at the first node using the first cipher key;
• generate a first signature based on the user data;
• transmit a start frame including the parameter data set, the encrypted user data, and the first signature at a first signature location in the start frame;
• and
• a second node storing the synchronized data set and configured to
• receive the start frame;
• select one or more of the plurality of values in the parameter data set in the received start frame using the first seed value stored at the second node, to form a second parameter subset equivalent to the first parameter subset;
• generate the first cipher key using the second parameter subset;
• decrypt the encrypted user data using the first cipher key;
• and
• verify the signature in the received start frame.

A method for secure communication, the method comprising:

• storing, at a first node of a first security group of one or more security groups, a parameter data set containing a plurality of values, the first security group having a first plurality of nodes each having a synchronized data set, the synchronized data set having at least a first seed value;
• selecting, using the first seed value stored at the first node, one or more of the plurality of values in the parameter data set to form a first parameter subset;
• generating a first cipher key at the first node using the first parameter subset;
• encrypting user data at the first node using the first cipher key;
• generating a first signature based at least the user data;
• and
• transmitting, from the first node to a second node of the first security group, a first start frame including the parameter data set, first encrypted user data, and the first signature at a first signature location in the first start frame.
