“…In combination with a set of configuration parameters, the storage of path delays provide distinct advantages over response bitstrings by enabling a very large, exponential set, of response bitstrings to be generated using a fixed set of stored path delays on the verifier. This paper builds on the work described in [6,8]. The novel contributions of this paper over previous work are:…”

This paper describes an authentication protocol using a Hardware-Embedded Delay PUF called HELP. HELP derives randomness from within-die path delay variations that occur along the paths within a hardware implementation of a cryptographic primitive, such as AES or SHA-3. The digitized timing values which represent the path delays are stored in a database on a secure server (verifier) as an alternative to storing PUF response bitstrings. This enables the development of an efficient authentication protocol that provides both privacy and mutual authentication. The security properties of the protocol are analyzed using data collected from a set of Xilinx Zynq FPGAs.

“…Although references describe previous research on HELP [4][5][6][7], no prior work exists that describes the distribution effect presented in this paper. We have found no related work that leverages the membership characteristics of a group of physical elements as a mechanism to increase bit string diversity.…”

Leveraging Distributions in Physical Unclonable Functions

A special class of Physical Unclonable Functions (PUFs) referred to as strong PUFs can be used in novel hardware-based authentication protocols. Strong PUFs are required for authentication because the bit strings and helper data are transmitted openly by the token to the verifier, and therefore are revealed to the adversary. This enables the adversary to carry out attacks against the token by systematically applying challenges and obtaining responses in an attempt to machine learn, and later predict, the token's response to an arbitrary challenge. Therefore, strong PUFs must both provide an exponentially large challenge space and be resistant to machine-learning attacks in order to be considered secure. We investigate a transformation called temperature-voltage compensation (TVCOMP), which is used within the Hardware-Embedded Delay PUF (HELP) bit string generation algorithm. TVCOMP increases the diversity and unpredictability of the challenge-response space, and therefore increases resistance to model-building attacks. HELP leverages within-die variations in path delays as a source of random information. TVCOMP is a linear transformation designed specifically for dealing with changes in delay introduced by adverse temperature-voltage (environmental) variations. In this paper, we show that TVCOMP also increases entropy and expands the challenge-response space dramatically.
