Mitigating the risk of side channel attacks requires a multi-faceted approach:
Encryption: Ensure all email communications are encrypted to make it harder for attackers to extract useful information. Randomization: Introduce random delays and noise in email processing to confuse timing analysis. Secure Hardware: Use hardware that is designed to resist side channel attacks, such as those with built-in countermeasures. Regular Audits: Conduct regular security audits to identify and address potential vulnerabilities.
