Abstract
A cryptographic method includes (1) with the first chiplet, parsing a message into one or more message blocks (2) dynamically generating a first target value that is associated with a first key (3) dynamically generating a second target value that is associated with a second key (4) encrypting at least one message block of the at least one or more message blocks to generate some ciphertext, the encryption being performed with at least one operation that includes at least one XOR operation, the at least one XOR operation performed at least in part with the first target value and with at least the second target value, the first target value and the second target value being accessed via the first and second keys, respectively; and (5) with at least one processing device associated with the first chiplet, transmitting the some ciphertext to a second chiplet.
