OBJECTIVE To describe previously unrecorded attachments of the ligamentum nuchae to the cervical posterior spinal dura, and to posterolateral parts of the occipital bone in an anatomical study, with particular reference to the deep aspects of the suboccipital triangle and upper cervical region. DESIGN Dissections of 10 heads and necks from embalmed(More)
A fully homomorphic encryption (FHE) scheme is envisioned as being a key cryptographic tool in building a secure and reliable cloud computing environment, as it allows arbitrarily evaluation of a ciphertext without revealing the plaintext. However, existing FHE implementations remain impractical due to their very high time and resource costs. Of the(More)

Digital signatures are an important primitive for building secure systems and are used in most real-world security protocols. However, almost all popular signature schemes are either based on the factoring assumption (RSA) or the hardness of the discrete logarithm problem (DSA/ECDSA). In the case of classical cryptanalytic advances or progress on the(More)
BACKGROUND Social media is an asset that higher education students can use for an array of purposes. Studies have shown the merits of social media use in educational settings; however, its adoption in health science education has been slow, and the contributing reasons remain unclear. OBJECTIVE This multidisciplinary study aimed to examine health science(More)
—Large integer multiplication is a major performance bottleneck in fully homomorphic encryption (FHE) schemes over the integers. In this paper two optimised multiplier architectures for large integer multiplication are proposed. The first of these is a low-latency hardware architecture of an integer-FFT multiplier. Secondly, the use of low Hamming weight(More)
