We can be optimistic because most IA32 attack codes are at least dozens of bytes long, but if a software flaw existed that was exploitable with, say, a single 1-byte opcode, then RISE would be vulnerable, although the process of guessing even a 1-byte representation would cause system crashes easily detectable by an administrator. An alternative path for an attacker is to try to inject arbitrary address ranges of the process into the network, and recover the key from the downloaded information.

8, No. 1, February 2005. 46 • D. Liu et al. assign each polynomial a unique ID. For each sensor node i, the setup server picks a subset of polynomials Fi ⊆ F, and assigns the shares of these polynomials to node i. The main issue in this phase is the subset assignment problem, which specifies how to pick a subset of polynomials from F for each sensor node. Here we identify two ways to perform subset assignments: random assignment and predetermined assignment. 1 Random Assignment. With random assignment, the setup server randomly picks a subset of F for each sensor node.
