<p>A method for enabling secure communication between a first node in a distributed network and at least one second node in the distributed network by using a cryptographic key, including the steps of using an encrypting key to encrypt the cryptographic key to generate a wrap key in a secure hardware module, transmitting the wrap key to the at least one second node over a network, and decrypting the wrap key using the encrypting key to obtain the cryptographic key. A system for enabling secure communication in a distributed network by using a cryptographic key, including a first node transmitting the cryptographic key, a secure hardware module for encrypting the cryptographic key with a encrypting key to obtain a wrap key, a network for transmitting the wrap key, and a second node, the second node configured to decrypt the wrap key using the encrypting key to obtain the cryptographic key.</p> |
