Abstract
Methods for providing for secure communications across data networks, including untrusted networks. In one embodiment, the method comprises establishing security associations between devices on the network using a digital certificate and key exchange protocol. In one variant, the digital certificate comprises a public encryption key; the recipient of the certificate authenticates the sender using at least the signature, and then generates a cryptographic element (e.g., key), and initialization vector. The key is encrypted and sent back to the originator, where it is decrypted and used to encrypt datagrams sent between the devices. The initialization vector may be used to initialize the encryption algorithm on the receiving device.
