Modern cities are undergoing rapid expansion. The number of connected devices in the networks in and around these cities is increasing every day and will exponentially increase in the next few years. At home, the number of connected devices is also increasing with the introduction of home automation appliances and applications. Many of these appliances are becoming smart devices which can track our daily routines. It is imperative that all these devices should be secure. When cryptographic keys used for encryption and decryption are stored on memory present on these devices, they can be retrieved by attackers or adversaries to gain control of the system. For this purpose, Physical Unclonable Functions (PUFs) were proposed to generate the keys required for encryption and decryption of the data or the communication channel, as required by the application. PUF modules take advantage of the manufacturing variations that are introduced in the Integrated Circuits (ICs) during the
fabrication process. These are used to generate the cryptographic keys which reduces the use of a separate memory module to store the encryption and decryption keys. A PUF module can also be recon gurable such that the number of input output pairs or Challenge Response Pairs (CRPs) generated can be increased exponentially. This dissertation proposes three designs of PUFs, two of which are recon gurable to increase the robustness of the system.
