Are there any successful cases of timing attacks over the internet?

Summary

: Yes, there have been successful cases of timing attacks over the Internet. Timing attacks exploit variations in the time taken by a system to respond to requests or perform specific tasks. These attacks can be used to extract sensitive information from systems that rely on cryptographic algorithms, such as RSA and ECC.

1. Introduction
– Timing attacks are a type of side-channel attack that exploits variations in the time it takes for a system to respond to requests or perform specific tasks. These attacks can be used to extract sensitive information from systems that rely on cryptographic algorithms, such as RSA and ECC.
– In this article, we will explore successful cases of timing attacks over the Internet and discuss ways to mitigate these attacks.

2. Successful Cases of Timing Attacks over the Internet
– One of the most famous cases of a successful timing attack is the Dual_EC_DRBG scandal in 2007. Dual_EC_DRBG was a random number generator that was used in various security protocols, including SSL and TLS. Researchers found that an attacker could use a timing attack to determine the output of the random number generator and thereby compromise the security of the system.
– In 2013, researchers demonstrated a timing attack against the Elliptic Curve Cryptography (ECC) algorithm used in the SSL/TLS protocols. The attack was able to extract the private key of an ECC implementation by measuring the time it took for the system to respond to requests.
– In 2015, researchers demonstrated a timing attack against the RSA algorithm used in many security protocols. The attack was able to recover the private key of an RSA implementation by analyzing the time it took for the system to perform modular exponentiation operations.

3. Mitigating Timing Attacks
– There are several ways to mitigate timing attacks over the Internet:
– Randomization: Implementations can randomize the amount of time taken to perform cryptographic operations, making it difficult for an attacker to detect any patterns in the response times.
– Hardware Security Modules (HSMs): HSMs provide a secure environment for performing cryptographic operations, isolating them from external timing attacks.
– Software Defined Radio (SDR): SDR can be used to monitor and measure radio frequency signals emitted by devices during cryptographic operations, allowing attackers to detect variations in response times. However, SDR-based attacks require physical access to the device being attacked.

Conclusion

– Timing attacks are a real threat to the security of systems that rely on cryptographic algorithms. While there have been successful cases of timing attacks over the Internet, there are also ways to mitigate these attacks. Implementations can randomize response times, use HSMs, or monitor for SDR-based attacks to protect against timing attacks.
