Description
The device does not contain sufficient protection
mechanisms to prevent physical side channels from exposing
sensitive information due to patterns in physically observable
phenomena such as variations in power consumption,
electromagnetic emissions (EME), or acoustic emissions.
Modes of Introduction:
– Implementation
Related Weaknesses
CWE-203
CWE-203
Consequences
Confidentiality: Read Memory, Read Application Data
Potential Mitigations
Phase: Architecture and Design
Description:
Apply blinding or masking techniques to implementations of cryptographic algorithms.
Phase: Implementation
Description:
Add shielding or tamper-resistant protections to the device to increase the difficulty of obtaining measurements of the side-channel.
