Secure computation revolves around a fundamental question: Is it possible for multiple individuals to run a joint computation while concealing all information about the data involved in the computation? This question has fascinated cryptographers, complexity theorists, and security enthusiasts ever since it was first scientifically studied in the early 80s. In essence, it asks how finely one can control the information leaked by a conversation.

Secure computation revolves around a fundamental question: Is it possible for multiple individuals to run a joint computation while concealing all information about the data involved in the computation? This question has fascinated cryptographers, complexity theorists, and security enthusiasts ever since it was first scientifically studied in the early 80s. In essence, it asks how finely one can control the information leaked by a conversation.
