Description: Adaptive cryptography refers to a set of cryptographic techniques that can adjust to the changing security requirements of various systems. As threats and vulnerabilities evolve, adaptive cryptography allows encryption and authentication methods to be modified to maintain the integrity and confidentiality of information. This flexibility is crucial in a digital environment where cyberattacks are becoming increasingly sophisticated. Key features of adaptive cryptography include the ability to change algorithms, keys, and protocols in response to new threats, as well as the implementation of machine learning mechanisms that can identify attack patterns and adjust defenses in real-time. The relevance of this technique lies in its potential to offer robust and dynamic security, in contrast to static systems that may become obsolete against new attack techniques. In a world where information is a valuable asset, adaptive cryptography emerges as an essential solution for protecting sensitive data and ensuring trust in digital communications.
