Abstract:
1. A method of distributing encryption keys among nodes in a mobile ad hoc network, comprising: creating a private key and a public key based on a first encryption method by a first node; transmitting, by the first node, the created public key to a second node and receiving parameters encrypted with the public key based on the first encryption method from the second node; decrypting, by the first node, the parameters by using the private key of the first node; creating, by the first node, a private key, a public key and a common key based on a second encryption method by using the decrypted parameters; and encrypting, by the first node, the public key based on the second encryption method with a public key of the second node based on the first encryption method, and then transmitting the encrypted public key to the second node; wherein the parameters comprise global public elements which are used in creating the private key of the first node based on the second encryption method; wherein the parameters comprise the public key of the second node based on the first encryption method, the global public elements, and the public key of the second node based on the second encryption method.
