Abstract
This disclosure includes techniques for using multiple cryptographic certificates for a secure connection. One embodiment is a method including: receiving by a client N public encryption keys over a network from a server, wherein N is an integer greater than 1; generating N session keys in response to receiving the N public encryption keys; encrypting each of the N session keys with a respective one of the N public encryption keys; subsequent to encrypting each of the N session keys, sending the N session keys encrypted over the network to the server; encrypting, with a first one of the N session keys, a first portion of a payload associated with a first message; encrypting, with a second one of the N session keys, a second portion of the payload associated with the first message; and sending the first message, comprising the payload encrypted, to the server from the client.
