A dynamic computer communication security encryption method or system using an initial seed key and multiple random number generators of a specific design, whereby a sequence of independent random entropy values is produced by one set of random number generators and encrypted along with the message stream using the initial seed key, or the output of a second set of random number generators initialized with the initial seed key, and following the subsequent transmission of the variable encrypted entropy / message block, the entropy values are used to symmetrically or identically augment or increase the current uncertainty or entropy of the cryptosystem at both the sender and the receiver, prior to the next encryption block operation. The encryption process effectively entailing the use of multiple encryption ciphers, and the entropy augmentation process entailing the encryption or application of various logical mathematical operations on the already dynamic but deterministic internal state values of the second set of random number generators, effectively altering their deterministic outputs in a random probabilistic manner.Random length message value sequences from one or more data sources is combined with one or more random length entropy value sequences from an independent source, following which the entropy “updates” may also be used to alter, or change any cryptosystem variable, value or component in a randomly determined manner. In addition, whilst ensuring synchronization, the random entropy sequences also serve to “pollute” the cipher-stream and thereby hinder most current forms of cryptanalysis, whilst simultaneously injecting additional entropy into the cryptographic system and allowing for its propagation to affect any connected system nodes, and thereby introducing unpredictable entropy into the system pseudorandom number generator outputs, and thereby ensuring the perpetual generation of unpredictable random numbers.Super-encryption mechanics are independent of the user data, simple, fast and efficient, and can incorporate compression, error correction and asymmetric encryption authentication routines. But most importantly, super-encryption ensures resistance to brute force attacks (not possible to verify if a message was even sent), an ability to exceed “perfect secrecy” requirements, and an improvement on previous super-encipherment design, since overhead can be dramatically reduced from 100% overhead.Communication links previously established by system nodes with central authorities may be used for secure node authentication and registration, whilst allowing the central authority to broker and synchronize communication channels and providing mutual authentication and other security functions between the system nodes.

To address the security requirements for cyber-physical systems, embodiments of the present invention include a resilient end-to-end message protection framework, termed Resilient End-to End Message Protection or REMP, exploiting the notion of the long-term key that is given on per node basis. This long term key is assigned during the node authentication phase and is subsequently used to derive encryption keys from a random number per-message sent. Compared with conventional schemes, REMP improves privacy, message authentication, and key exposure, and without compromising scalability and end-to-end security. The tradeoff is a slight increase in computation time for message decryption and message authentication.

The present invention provides methods and devices for a security architecture for use in wireless multi-hop networks. A method for implementing pair-wise encryption key establishment, network node authentication and determining tunnel encryption keys is provided in a following manner. In a multi-hop wireless network including a plurality of network nodes, pair-wise security is established between pairs of neighbouring network nodes of the plurality of network nodes. For example, pair-wise security is established in the form of temporal pair-wise encryption keys. Following establishment of pair-wise security between pairs of neighbouring network nodes, for a pair of network nodes that are not neighbours, tunnel security is established between the pair of network nodes using tunnel encryption keys derived by the pair of network nodes on an ad hoc basis. The tunnel encryption keys are used to form the connection between non-neighbouring network nodes so as to avoid the hop-by-hop encryption / decryption used in conventional multi-hop wireless systems.

The invention consists of an authentication protocol for the Home Agent to authenticate and authorize the Mobile Node's Binding Update message. Two new mobility options compatible with RADIUS AAA are used to exchange a shared secret between the Home Agent and the Mobile Node so the Mobile Node can be authenticated. A Mobile Node-AAA authenticator option is added to the Binding Update message. The Home Agent generates the Mobile Node-AAA authenticator as a shared secret that it communicates as authentication data to the RADIUS AAA server on the home network. The RADIUS AAA server authenticates the communication and generates an Access-Accept message with a Mobile Node-Home Agent authenticator option. After receipt at the Home Agent, a Binding Update message with the Mobile Node-Home Agent authenticator option is transmitted from the Home Agent to the Mobile Node to use as an authenticator.

A solution of relay node authentication is proposed. The solution includes mutual authentication of relay node and relay UICC, mutual authentication of relay node and network, secure channel establishment between relay UICC and relay node. AKA procedure in TS 33.401 is re-used so that no extra NAS message is needed. IMEI is sent to network in the initial NAS message, according to which MME-RN can retrieve RN's public key from HSS, and perform access control for DeNB. MME-RN will generate a session key based on IMSI, IMEI and Kasme, and encrypt it by RN's public key and send it to RN. UICC will also generate the same key and thus RN can authenticate both UICC and network. When the key or other parameters sent between UICC and RN do not match, UICC or RN will send Authentication Reject message with a new cause to inform network.

The invention provides for disabling communication at the access router on a visited network that supports mobile IP v6 and the home address destination option. Until a home agent or a correspondent node authenticates the home IP address of the mobile node and the access router verifies this address, the mobile node is unable to communicate with other resources over the visited network. If the home IP address included in a binding acknowledgement message is verified by the access router and affirmatively compared to the state of a corresponding binding update message from the mobile node, the access router enables subsequent messages to be communicated over the visited network between the mobile node and other resources.
