A central task in position-based cryptography is the problem of secure positioning. ...
The goal of position-based cryptography is to use the geographical position of a party as its only "credential". ...
Then in order to authenticate a position i in which m ′ i = m i , the adversary must call P at least N/8 times with positions that are not in ci , i.e., at least N/8 bits of cj , j = i, otherwise his success ...
