Abstract: This paper presents a survey of key evolving cryptosystems in the public key setting, focusing on two main approaches: |forward security| and |intrusion resilience|. The essential feature of this design strategy is that the secret key changes over time, while the corresponding public key remains unchanged. Key evolving cryptosystems can limit the damage caused by an attacker who occasionally learns your secret key.

Keywords: public keys; cryptography; key evolution; forward security; intrusion resilience; networks; secret keys.
