Abstract
Systems and/or methods that facilitate security of data are presented. A random number generation component generates random numbers based in part on electron activity in a select memory cell(s) to facilitate data security. Sensor components that are highly sensitive can be employed to sense activity of the select memory cell(s) and/or reference memory cell in a noise margin associated with respective memory cells in the memory component. The activity of the select memory cell is compared to the reference memory cell(s) to facilitate generating binary data. The binary data is provided to the random number generation component where the binary data is evaluated to determine whether a predetermined level of entropy exists in the binary data. The binary data, or a portion thereof, can be processed to generate random numbers that are utilized in cryptographic processes and/or as a physical signature to facilitate data security.
