Adversary Sample Clauses

Adversary. The adversary is a very powerful agent with powerful computing resources. It is able to move about freely in the deployment space to monitor transmissions, replay messages and insert its own fabricated messages. It is also able to physically capture nodes and extract all the keying material, including the public key IDs, the private key sets S and the keying parameters from ROM and RAM memory.

Adversary. The adversary is neither a client, nor the server, and in our formalization it is given enormous capabilities to closely model its abilities in the real life: the adversary can tap on the wire to eavesdrop, delete, delay, insert, replay, modify messages. We model these capabilities through the following queries: – The adversary has the ability to send arbitrary messages to the base station S using the SendServer-query. This query on input a message m returns the message that S would have produced in processing the message. If the message is not a valid one, the query returns a special symbol ⊥. The query SendServer(setup, J ) (resp. SendServer(join, J ) and SendServer(remove, J )) return the flows output by the base station when initiating a Setup( ) (resp. Join( ) and Remove( )) depending on the scheme. A ⊥ – The adversary has the ability to send arbitrary messages to clients using a Send-query. This query on input a client Ui and a message m returns the message Ui would have produced in processing the message. If the message is not a valid one, a special symbol is returned. The queries Send(setup, ), Send(join, ) and Send(remove, ), respectively, return the flows output by the client when initiating a Setup( ), Join( ) and Remove( ), respectively, depending on the scheme. A – Known-key attacks are modeled by the Reveal-query. This query allows the adversary to learn the value of a particular session key sk, if of course the attacked player (client or server) has already computed the key. This query on input a player returns sk to the adversary but not the player internal state. A – Forward-secrecy is modeled through the Corrupt-query. This query allows to learn the value of long-lived keys. This query on input a player returns to the adversary the value of the long-lived keys. Forward-secrecy means that loss of a LL-key does not compromise the semantic security of previously-distributed session keys. The adversary has, unlike in the wired environment, true and full control over the com- munication medium. The adversary can cut off mobiles, modify the mobile network topology and make mobiles disappear and reappear continuously. The adversary’s abilities to modify the network topology are modeled through the following queries: J – The Send/SendServer(setup, )-queries provide the adversary the capability to bring to- gether a pool of players. – The Send/SendServer(remove, )-queries provide the adversary the ability to make clients disappear. – The Send/Send...

Adversary. Adversary A 1 does not have access to the master key, but A 1 can replace the public keys of any entity with a value of his choice, since there is no certificate involved in CLPKC.
