Introduction Computer security is undeniably important, and as new vulnerabilities are discovered and exploited, the perceived need for new security solutions grows. "Trusted computing" initiatives propose to solve some of today s security problems through hardware chAnges to the personal computer. Changing hardware design isn t inherently suspicious, but the leading trusted computing proposals have a high cost: they provide security to users while giving third parties the power to enforce policies on users computers against the users wishes -- they let others pressure you to hand some control over your PC to someone else. This is a "feature" ready-made for abuse by software authors who want to anticompetitively choke off rival software. It needn t be this way: a straightforward chAnge to the plans of trusted computing vendors could leave the security benefits intact while ensuring that a PC owner s

The combinatorial core of the OVSF code assignment problem that arises in UMTS is to assign some nodes of a complete binary tree of height h (the code tree) to n simultaneous connections, such that no two assigned nodes (codes) are on the same root-to-leaf path. Each connection requires a code on a specified level. The code can chAnge over time as long as it is still on the same level. We consider the one-step code assignment problem: Given an assignment, move the minimum number of codes to serve a new request. Minn and Siu proposed the so-called DCAalgorithm to solve the problem optimally. We show that DCA does not always return an optimal solution, and that the problem is NP-hard. We give an exact nO(h)-time algorithm, and a polynomial time greedy algorithm that achieves approximation ratio Θ(h). Finally, we consider the online code assignment problem for which we derive several results
