A key-encapsulation mechanism (KEM) is a set of algorithms that, under certain conditions, can be used by two parties to establish a shared secret key over a public channel. A shared secret key that is securely established using a KEM can then be used with symmetric-key cryptographic algorithms to perform basic tasks in secure communications, such as encryption and authentication. This standard specifies a key-encapsulation mechanism called ML-KEM. The security of ML-KEM is related to the com...| csrc.nist.gov

At Open Whisper Systems, our goal is to make private communication simple. A year ago, we announced a partnership with WhatsApp and committed to integrating the Signal Protocol into their product, moving towards full end-to-end encryption for all of their users by default. Over the past year, we...| Signal Messenger
