## Timing Attacks

Timing attacks are a type of side-channel attack where the time taken to execute a cryptographic algorithm is measured to infer information about the secret key. If a function takes a different amount of time to process based on the value of the key bits, an attacker can measure these variations to reconstruct the key.

This is a common vulnerability in software implementations of cryptography that do not account for constant-time execution. In the financial domain, where every millisecond counts, developers must ensure that sensitive operations do not leak information through execution duration.

Protecting against this involves implementing algorithms that perform the same number of operations regardless of the input data. It is a critical aspect of writing secure code for high-stakes financial applications.
