“…Because of the encryption process, even if the transaction data is captured during transmission, it will still be unreadable and useless to outsiders. Only the authorized recipient, such as the card issuer or the payment terminal, can decrypt the encrypted data using the proper encryption keys (Furkan Altınok, Peker, Tezcan, & Temizel, 2022). Additionally, contactless cards frequently use tokenization, lowering the danger of hacking card information by substituting distinct tokens for the actual card details (Al-Maliki & Al-Assam, 2022).…”

The contactless bank card is a replica of the old fashion payment methods. The contactless card saves the customer a lot of time and effort because the cardholder can tap the card on the card reader instead of carrying a massive amount of cash or memorizing a long password. The transaction will be done in a few seconds, which is a magnificent technique for a very rush and speedy world like this. However, because the contactless card does not require a PIN or signature, it is vulnerable to different types of attacks, and the card can be used by every single person who has the card, even if they are not the real cardholder. Nevertheless, for each new problem, there is a unique solution. Hence this paper presents an innovative way to overcome this problem by embedding a fingerprint sensor into the contactless card to add an extra level of security by creating a virtual environment giving a contactless card and using a minutiae-based algorithm for fingerprint recognition in this contactless card. The work is evaluated based on accuracy using two metrics, false acceptance rate (FAR) and false rejection rate (FRR), algorithm’s matching time, and transaction time. This work shows a good result regarding the transaction time and the possibility of integrating the fingerprint into the contactless card. It displays how fingerprint image quality and features affect fingerprint authentication results. However, it also shows that minutiae-based techniques are not adequate when the dataset is relatively small and has data with low-quality and/or noisy data.

The ARIA block cipher algorithm is Korean standard, IETF standard (RFC 5794), and part of the TLS/SSL protocol. In this paper, we present the parallel implementation of ARIA block cipher on ARMv8 processors and GPU. The ARMv8 processor is the latest 64-bit ARM architecture and supports ASIMD for parallel implementations. With this feature, 4 and 16 parallel encryption blocks are implemented to optimize the substitution layer of ARIA block cipher using four different Sboxes. Compared to previous works, the performance was improved by 2.76× and 8.73× at 4-plaintext and 16-plaintext cases, respectively. We also present optimal implementation on GPU architectures. GPUs are highly parallel programmable processors featuring maximum arithmetic and memory bandwidth. Optimal settings of ARIA block cipher implementation on GPU were analyzed using the Nsight Compute profiler provided by Nvidia. We found that using shared memory reduces the execution timing when performing substitution operations with Sbox tables. When using many threads with shared memory instead of global memory, it improves performance by about 1.08∼1.43×. Additionally, techniques using table expansion to minimize bank conflicts have been found to be inefficient when tables cannot be copied by the size of the bank. We measured the performance of ARIA block ciphers implemented with various settings. This represents an optimized GPU implementation of the ARIA block cipher.
