CWE-1300 – Improper Protection of Physical Side Channels

Read Time:59 Second

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.
