Abstract:
An improved approach to public key passing is provided to inhibit man-in-the-middle (MITM) attacks during an exchange of public keys over one or more public networks. In one embodiment, a method for securely passing public keys includes encrypting a first user public key, wherein the first user public key is associated with a first user device. The method also includes passing the encrypted first user public key to a first gateway server over a secure communication link. The method further includes receiving an encrypted second user public key from the first gateway server over the secure communication link, wherein the second user public key is associated with a second user device, and wherein the second user device is associated with a second gateway server. In addition, the method includes decrypting the second user public key.
