Abstract
The present application describes a method, system, and non-transitory computer-readable medium for exchanging encrypted communications using hybrid cryptography protocol. According to the present disclosure, a first device divides a first communication into at least a first secret and a second secret. The first device encrypts the first secret using a first cipher suite and the second secret using a second cipher suite. The first device generates a first signature of the first encrypted secret and the second encrypted secret according to a first signature generation algorithm associated with the first cipher suite and a second signature of the first encrypted secret and the second encrypted secret according to a second signature generation algorithm associated with the second cipher suite. The first device transmits the first encrypted secret and the second encrypted secret, the first signature, and the second signature to the second device.
