“…While significant investment continued to be put into QR codes along with ingenious visions of the technology’s role, QR and other barcodes were widely believed to soon be eclipsed by the development of a replacement for QR codes, Radio Frequency Identification (RFID) technology, with their new standards, device, and network infrastructure for object identification heralding the Internet of Things (IoT) (Chabanne et al, 2013: 94). Actually, it turns out that the trajectory of RFID and its “infrastructures of identification” (Frith, 2019) are recursive.…”

“…The invention of the barcode in 1970 (credited to Ted Williams) formed a watershed moment. Barcodes used different protocols to represent information via encoding and symbolization to be read by an optical laser scanner (Chabanne et al, 2013). The first kind of barcodes were one-dimensional (or linear) developed through various standards (Berry, 2013), and were later extended via “stacked linear” barcodes.…”

In this article, we explore Quick Response (QR) codes (machine-readable optical labels that link to information) and how, after a period of having fallen out of favor, they have been reactivated and have come to underpin COVID-19 automation and contact-tracing efforts. During the pandemic, they were used especially for “safe entry” and other kinds of check-in to locations to facilitate contact tracing. In this context, QR codes facilitate automated decision-making in relation to infectious disease surveillance and disease outbreak control. However, the use of QR codes for contact-tracing purposes has enjoyed mixed success and its implementation has encountered several challenges, as we illustrate through a case study that explores QR codes and COVID contact tracing in Singapore and Australia.

“…Bringer et al [24] used a white-box implementation of the AES algorithm by inserting scrambled terms. The means used is to add scrambling to the original scheme, which makes the algebraic structure more complex and thus much more difficult for an attacker to carry out the attack.…”

The attacker in white-box model has full access to software implementation of a cryptographic algorithm and full control over its execution environment. In order to solve the issues of high storage cost and inadequate security about most current white-box cryptographic schemes, SPN-AS, a novel white-box block cipher based on AS iterative structure is proposed. This scheme utilizes the AS iterative structure to construct a lookup table with a five-layer ASASA structure, and the maximum distance separable matrix is used as a linear layer to achieve complete diffusion in a small number of rounds. Attackers can be prevented from recovering the key under black-box model. The length of nonlinear layer S and affine layer A in lookup table is 16 bits, which effectively avoids decomposition attack against the ASASA structure and makes the algorithm possess anti-key extraction security under the white-box model, while SPN-AS possesses weak white-box (32KB, 112)-space hardness to satisfy anti-code lifting security. SPN-AS has provable security and better storage cost than existing schemes, with the same anti-key extraction security and anti-code lifting security, only 128KB of memory space is required in SPN-AS, which is only 14% of SPACE-16 algorithm and 33% of Yoroi-16 algorithm.
