....list is onion encrypted [57] Each route is specified by an address indicating the next hop, an HMAC of the packet (not including the list) and the encrypted remaining list. Both the HMAC and the encrypted remaining list are computed with the shared key between the source and that node. An HMAC [4] using a one way hash function such as SHA1 [1] and a standard block cipher encryption algorithm such as AES [3] can be used. When a node receives a packet it verifies the HMAC of the packet and decrypts the remainder of the source route using its shared key with the source. If the HMAC verifies, ....

....As mentioned in [25] source authentication is more of a concern in routing than confidentiality. Papadimitratos and Haas showed in [42] how im personation and replay attacks can be prevented for on demand routing by disabling route caching and providing end to end authentication using an HMAC [4] primitive which relies on the existence of security associations between sources and desti nations. Dahill et al. 19] focus on providing hop by hop authentication for the route discovery stage of two well known on demand protocols: AODV [44] and DSR [30] relying on digital signatures. Other ....

.... Integrity and confidentiality: protect the contents of the communication both from eavesdropping as well as undetected modification. An encryption mode may provide just confidentiality, or it may also provide integrity, however, in general, data integrity is usually achieved via MAC (e.g. HMAC [1]) algorithms. We distinguish among two basic approaches to integrating security services into a client server GCS. The first approach (referred to as the layered architecture) places security services in a client library layered atop the GCS client library. The second approach entails housing ....

.... key changes (time out) or maximum volume of data exchanged (data out) Generation of client group keys is much less costly in the integrated architecture, since, if no change occurs in the servers configuration, the cost of generating a new key for a group amounts to one keyed MAC (HMAC [1]) operation. When network connectivity does change (and so does the membership of the server group) the group key shared by the servers is refreshed using a full blown group key agreement protocol. For this, we use the TGDH [27] protocol because of its superior performance. The use of encryption ....

....[17] Each probe is specified by the identifier of the node, an HMAC of the packet (not including the list) and the encrypted remaining list (see Lines 3 6, Figure 4) Both the HMAC and the encrypted remaining list are computed with the shared key between the source and that node. An HMAC [12] using a one way hash function such as SHA1 [35] and a standard block cipher encryption algorithm such as AES [36] can be used. A node can detect if it is required to send acks by checking the identifier at the beginning of the list (see Lines 8 12, Figure 4) If it matches, then it verifies the ....
