Public-key cryptography is like a superhero for your cybersecurity needs. Essentially, it's an advanced method of encrypting data that uses two keys: one public and one private. The public key can be shared with anyone and allows others to encrypt messages that can only be decrypted using the private key, which is kept secret by the owner. This tech trend is on the rise with various sub-trends appearing under its umbrella, such as passwordless authentication and the principle of least privilege. These trends indicate that businesses are starting to take cybersecurity seriously, with a growing focus on user-centric security and the need to reduce risky behaviors. Expect to see more advancements in public-key cryptography and related fields as businesses strive to stay ahead of the ever-evolving threat landscape.
