Computing Resources. NJIT students taking courses offered at the MCCC campus will have access to all computer software available to students attending the same degree program at the NJIT main campus. Students will be provided technical support via the NJIT Computing Help Desk which is accessible remotely. Basic technology support will be also offered to these students through the corresponding MCCC office/unit.
Computing Resources. The visitor needs computing resources for checking whether a received voucher is valid or not e.g. verifying the voucher signature. Also, computing re- sources are needed for the visitor to get authenticated to the issuing party upon delivering the voucher. From the webserver perspective, computing resources are required to verify and agree on received vouchers. Also, such resources are needed in case specific vouchers are sent to visitors based on specific criteria e.g. specific time. Regarding the issuing party, initially it has to construct and agree on vouchers with webservers. Also, it has to check received vouchers from visitors against its repository. For processing-based schemes, computing resources are used both at the webserver and the visitor sides depending on the computations required by the challenge. Also, the audit agency needs computing resources to construct the challenge and check its result. – Communication The voucher size should be typically small. The signature can be attached to the voucher as done in appendix signature schemes or recovered from the voucher as in message recovery signature schemes. The second scheme, where the voucher is recovered from the signature, will save communica- tion overhead. Initially, the voucher has to be communicated to webserver. During the visitor-webserver interaction, the webserver sends the voucher to the visitor who typically sends it again to the issuing party. Typically in processing-based schemes, only the computational result, which is relatively small, has to be communicated among the web metering entities. – Storage The webserver has to store received vouchers before submitting them to visitors or forward them on-the-fly to visitors. Similarly, the visitor has to store the received vouchers before submitting them to the issuing party or directly forward the received voucher to the issuing party. Processing-based schemes do not require storage requirements as the required information is typically communicated online.
Computing Resources. Depending on the third-party-centric scheme, computing resources at the visitor and webserver are needed accordingly. Script-based schemes should require more computing resources at the visitor than audit-based schemes because a script is executed at the visitor side. There are no computing resources required for In- line schemes, besides the codes and their replies, as the third party intercepts the visitors’ requests. • Communication There are no additional communication messages required at In-line schemes as the normal traffic is captured at the intercepting party. Generally, depending on the audit-based scheme, additional messages have to be communicated to the webserver and the visitor to initialise the scheme. Similarly, depending the exe- cuted script at script-based schemes, messages are sent to the metering provider accordingly. Calling and executing such tracking code require the visitor to have separate inbound and outbound connections to the third party. • Storage There is no storage requirements for both In-line and script-based schemes. How- ever depending on the audit-based schemes, there can be storage requirements at the visitor side e.g. storing the hash chain described in [19].

Computing Resources the Faculty and the Linguistics Department will provide those employed on the project with relevant state-of-the-art desktop and/or laptop computers (both IBM and Macintosh are supported); all Faculty offices have high-speed internet connections. Through the University Library, nearly all current and past linguistics journals are available electronically, as are the major databases such as the World Atlas of Language Structures (xxxx://xxxx.xxxx/), The Syntactic Structures of the World’s Languages (xxxx://xxxx.xxxxxxxxxxxxxxx.xxx/) and the Konstanz University database of universals (xxxx://xxxx.xxx-xxxxxxxx.xx/archive/intro/). Library resources: Cambridge University Library is one of four deposit libraries in the UK, holding all UK publications. Partly because of this and partly because of a traditionally very generous acquisitions policy, the Library has excellent holdings in all areas related to Linguistics. Most importantly for the present project, these holdings include numerous grammars of languages from all over the world. This clearly represents an invaluable resource for the present project. In addition to the University Library, there are College, Faculty and Departmental libraries, which in many cases offer access to hard-to-find grammars and other relevant linguistic resources. Finally, the University Library’s online catalogue is linked to the following libraries worldwide: the Catalogue collectif de France, the Deutsche Bibliothek Database, LibDex (an index to 17,000 University, Further Education and Public libraries worldwide), the Library of Congress, the Karlsruhe Virtual Catalog, the National Library Catalogues Worldwide, WorldCat (OCLC) and The European Library.
