WebExamples of public-key cryptography include: RSA, used widely on the internet Elliptic Curve Digital Signature Algorithm (ECDSA) used by Bitcoin Digital Signature Algorithm (DSA) … WebTLS is an example of implementing PKI over TCP. This is used to prevent a MITM attack over a secured HTTP connection on internet. The defense is that client and server exchange PKI certificates issued and verified by a common certificate authority. Mutual authentication is the main defense in a PKI scenario.
