The indications of circuit activity in an electrical signal may be obtained by monitoring the electrical terminal or wire by way of an electrical connection or by sensing changes in magnetic and electric fields. A cloaking circuit may be coupled to the electrical terminal to obfuscate the indications of circuit activity of the processing circuit to reduce or avoid successful monitoring that may lead to a breach of data security. Obfuscating the indications of circuit activity includes modifying a signal on the electrical terminal to render the circuit activity more obscure, unclear, or unintelligible. In some examples, modifying the signal on the electrical terminal may include generating a cloaking signal on the electrical terminal. In some examples, generating the cloaking signal may include analyzing the signal to detect indications of circuit activity and generating the cloaking signal based on the circuit activity.
