RFID is an identication technology that has a wide range of applications. One of the main areas of interest is the Supply Chain Management (SCM), traceability management, multimodality shopping, etc. In suppy chains readers are placed into manufacturing facilities, the supplier attaches RFID tags to all outgoing products and some data is stored on each tag , attached to the products. At each stage, every player in the supply chain will be able to track relevant information on the product. The information can be used to ensure quality, on time delivery, fast re-stocks, ad hence greater overall e ciency. NSCCA (Nested Supply Chain Cryprographic System) is an algorithm derived from the Nested Cryptographic Algorithm, that aims to ensure authenticity, privacy and protection along one suppy chain, and is based on public cryptog- raphy. The scope of this project is to develop a programming class library and an appli- cation that implement the NSCCA algorithm, as well as testing its performance, as well as an interface that permit to communicate through an RFID reader in order to save and load the result of the algorithm in RFID tags. structure of this report is as follows: In Chapter 2, some important concepts involved in the project are explained, as well as the NSSCA algorithm, public key cryptography and RFID technology. Then, in Chapter 3 the development framework (programming language, ID) is explained, and the program structure is de ned. Continuing, the Chapter 4some tests on the platform are performed, and the main results are discussed. After that, in Chapter 5 there is a little user manual for the application developed to test the libraries. Finally, in Chapter 6 the conclussions on the project realization are explained.
