Abstract

Aspects of the invention include a computer-implemented method of executing a hybrid quantum safe key exchange system. The computer-implemented method includes initially retrieving an authenticated random value from a trusted source, generating a first Z value using a first elliptic curve (EC) private key and a first certified form of an EC public key with an EC Diffie-Hellman (ECDH) algorithm, deriving a shared key using the authenticated random value and the first Z value with a key derivation function, decrypting the authenticated random value using a quantum safe algorithm (QSA) private key, generating a second Z value using a second EC private key and a second certified form of the EC public key with the ECDH algorithm and deriving the shared key using the authenticated random value and the second Z value with the key derivation function.
