| Abstract | Photons can be exploited to reveal secrets of security ICs like smartcards, secure microcontrollers, and cryptographic coprocessors. One such secret is the secret key of cryptographic algorithms. This work gives an overview about current research on revealing these secret keys by exploiting the photonic side channel. Different analysis methods are presented. It is shown that the analysis of photonic emissions also helps to gain knowledge about the attacked device and thus poses a threat to modern security ICs. The presented results illustrate the differences between the photonic and other side channels, which do not provide fine-grained spatial information. It is shown that the photonic side channel has to be addressed by software engineers and during chip design. |

| Abstract | This paper explores the design of a QRNG based on a massively parallel array of SPAD. The matrix comprises 512x128 independent cells that convert photons onto a raw bit-stream of random bits. The sequences are read out in a 128-bit parallel bus, concatenated, and pipelined onto a de-biasing filter. Reported results, achieved on the manufactured devices, show that the architecture can reach up to 5 Gbit/s while consuming 25pJ/bit, demonstrating scalability and performance for any RNG based on SPADs. |

| Abstract | We report on a quantum key distribution (QKD) experiment where a client with an on-chip polarisation rotator can access a server through a telecom-fibre link. Large resources such as photon source and detectors are situated at server-side. We employ a reference frame independent QKD protocol for polarisation qubits and show that it overcomes detrimental effects of drifting fibre birefringence in a polarisation maintaining fibre. |
