Title: Sharing cryptographic material
Inventor: THOMAS PREST
IPC: H04L9/32
Filed: 2021-04-16
Abstract: A group of communications devices includes a first symmetric key generator and at least one second key receiver. The key receivers each create key encapsulation asymmetric key pairs dkj, ekj and make the public encapsulation key (ekj) available to the key generator. The key generator creates a symmetric key k using key encapsulation techniques on the set of encapsulation keys. The key generator creates a commitment tok based on the symmetric key. The key generator creates ciphertext ct from the symmetric key using the group keys. The ciphertext including a portion specific to each key receiver and possibly a common portion. The key generator sends relevant ciphertext portions and the commitment to each key receiver. Each key receiver recovers the symmetric key and validates it using the commitment. The system may reduce key message sizes in some instances and may be used with post quantum te
