Key Encapsulation Mechanism, also known as KEM, is a triple of algorithms and a corresponding key space , a ciphertext space with
- The algorithm takes a public parameter as an input and returns a public and secret-key pair ().
- The probabilistic (encapsulation) algorithms takes as an input and returns a ciphertext and a key .
- The deterministic (decapsulation) algorithm takes as inputs and returns a key , with denoting as a failure.
