“…Additionally, we plan to improve bandwidth efficiency and audio quality by implementing a more advanced audio codec in the PL. Moreover, the current implementation of NaCl on the MicroBlaze could be removed in favor of a pure hardware implementation since first results for Curve25519 seem to be promising [28].…”

In this work we propose a secure architecture for Voice-over-IP (VoIP) that encapsulates all security and privacy critical components and I/O functions into secure hardware and thus drastically reduces the underlying trusted computing base. Our proof-of-concept implementation shows that high security and reliance on established standards and software (e.g., device drivers, transmission control, and protocols) to keep development costs down are no contradiction. Security is ensured as all security and privacy critical operations of the VoIP system are performed in protected hardware and as a consequence a successful attack on any software component (e.g., buffer overflow) does not lead to a violation of security. All I/O devices like microphones, speakers, displays, and dial buttons are directly connected to the secure hardware and cannot be controlled by an adversary even if the software part has been compromised.

“…Other works [1,20,36,19,29,27] outperform our architecture in terms of speed, but use a much larger number of embedded multipliers. Also, implementations only focusing on NIST curves are able to use the special prime shape, yielding a significant speed-up.…”

Abstract. This work revisits the recent complete addition formulas for prime order elliptic curves of Renes, Costello and Batina in light of parallelization. We introduce the first hardware implementation of the new formulas on an FPGA based on three arithmetic units performing Montgomery multiplication. Our results are competitive with current literature and show the potential of the new complete formulas in hardware design. Furthermore, we present algorithms to compute the formulas using anywhere between two and six processors, using the minimum number of parallel field multiplications.

“…In fact, a parameter of that curve, can be decomposed into 15 × 17 bit blocks and then directly processed by the 18-bit block operations of the DSP embedded in most of the Xilinx devices. The two main blocks of our architecture, describe in [20] are the Modular Addition Unit and the Modular Multiplication Unit. The Modular Addition Unit block is composed by two DSP blocks supporting 18x25-bit multiplications and up to 48-bit additions, subtractions or accumulations.…”

Security and privacy of data traversing internet have always been a major concern for all users. In this context, The Onion Routing (Tor) is the most successful protocol to anonymize global Internet traffic and is widely deployed as software on many personal computers or servers. In this paper, we explore the potential of modern reconfigurable devices to efficiently realize the Tor protocol on embedded devices. In particular, this targets the acceleration of the complex cryptographic operations involved in the handshake of routing nodes and the data stream encryption. Our hardware-based implementation on the Xilinx Zynq platform outperforms previous embedded solutions by more than a factor of 9 with respect to the cryptographic handshake -ultimately enabling quite inexpensive but highly efficient routers. Hence, we consider our work as a further milestone towards the development and the dissemination of low-cost and high performance onion relays that hopefully ultimately leads again to a more private Internet.
