Forward Secure Asynchronous Messaging from Puncturable Encryption

Explore forward secure encryption mechanisms for asynchronous messaging systems in this IEEE Symposium on Security & Privacy presentation. Delve into the concept of puncturable encryption, allowing recipients to update decryption keys without sender communication. Learn how combining puncturable encryption with forward-secure public key encryption achieves practical, low-overhead messaging security. Examine implementation results and performance metrics, and consider the implications of key expiration in secure communication systems.
