.... [15] 16] 29] Recently, a set of techniques has been proposed for the protection of digital circuit IP through watermarking at various levels in the design hierarchy using the superimposition of additional constraints in conjunction to those specified by the user [9] 10] 17] 18] 24] [31]. In this paper, we propose the first fingerprinting technique for FPGA designs at the physical design level. Addressing the design at a lower level of abstraction has one additional advantage: all designs are significantly larger at lower levels of abstraction, enabling more and or larger marks ....

....proof of authorship, and very low overhead in terms of speed, area, and power. In the last several years a number of watermarking based IPP techniques have been developed at all levels of the design process, including system synthesis, behavioral synthesis, logic synthesis, and physical design [5, 6, 8, 13]. The key observation on which all watermarkingbased IPP techniques are based on is the fact that many synthesis problems are associated with computationally intractable or difficult optimization problems for which there exists a high number of different solutions with identical or Permission to ....

....the prominence of the Internet are creating a mounting need for copyright enforcement schemes to protect ownership. Hence, watermarking of digitized media is becoming increasingly common [3, 15] In the last three years, a number of watermarking based IPP techniques have been propsosed including [9, 10, 11, 13, 14]. Several cryptographic techniques are useful to the first step of our watermarking approach, that of finding a set of constraints for the instance of the optimization problem that is to be watermarked. The specific method we use involves the cryptographic hash function MD5 , the public key ....

The majority of intellectual property is already programmable components, and all economic and historical trends indicate that the importance of these components will continue to rise.

....documents. In [2] a hierarchical watermarking method was proposed for the protection of multiple design abstraction levels and for tracking purposes. Moreover, methods were proposed to watermark physical design phases in full and semi custom circuits [3] FPGAs [4, 4] and finite state machines [5, 6]. An alternative approach, known as tagging consists of generating a compressed representation of the hierarchy of a design using a given naming convention. The compressed hierarchy is then stored in a specific layer. The approach is less robust, as it is potentially easy to delete or recreate ....

....(FSMs) The technique consists of finding a sequence of states in the state transition diagram which is activated by a given sequence of (not necessarily legal) inputs. The corresponding sequence of outputs is also identified and the resulting sequence of input outputs is called IO signature [5]. Unlikeother approaches found in the literature [3, 4, 9] fingerprints do not require any modification of the original designs and they are used merely as a verification tool. Identical fingerprints are however extremely unlikely to be achieved in significantly different designs. The odds that ....

....watermark. Several authors have proposed to use other design constraints to implant watermarks. In [8] fixed placement and delay constraints implemented the watermark. In [9] a sequence of nodes in a multilevel logic function was permuted according to a seeded pseudorandom selection scheme. In [10] and [11] schemes have been proposed to implant watermarks in regular sequential functions by modifying the original function in a structured fashion. In this paper, we will focus on this kind of watermarking scheme, due to the omnipresence of regular sequential functions in industrial designs ....
