Two lightweight block cipher families, Simon and Speck, have been proposed by researchers from the NSA recently. In this paper, we introduce Simeck, a new family of lightweight block ciphers that combines the good design components from both Simon and Speck, in order to devise even more compact and efficient block ciphers. For Simeck32/64, we can achieve(More)
12-O-β-D-glucopyranosyl jasmonic acid (JAG) shows unique biological activities, including leaf-closing of Samanea saman. It is expected that the mode of action for such regulation is distinct from that of other jasmonates. We developed high-performance compact molecular probes (CMPs) based on JAG that can be used for the FLAG-tagging of JAG target. We(More)
WG-8 is a lightweight instance of the Welch-Gong (WG) stream cipher family, targeting for resource-constrained devices like RFID tags, smart cards, and wireless sensor nodes. Recent work has demonstrated the advantages of tower field constructions for finite field arithmetic in the AES and WG-16 ciphers. In this paper we explore three different tower field(More)
We investigated the potential for exploiting Stevia rebaudiana stem (SRS) waste as a source of edible plant-based antioxidants finding for the first time that the hot water extract of SRS had significantly higher antioxidant activity against fish oil oxidation than that of the leaf, despite SRS extract having lower total phenolic content, DPPH radical(More)
Pseudorandom number generators (PRNGs) are very important for EPC Class 1 Gener­ ation 2 (EPC C1 G2) Radio Frequency Identification (RFID) systems. A PRNG is able to provide a 16-bit random number that is used in many commands of the EPC C1 G2 standard, and it can also be used in future security extensions of the EPC C1 G2 standard, such as mutual(More)
12-O-β-D-Glucopyranosyljasmonic acid (JAG, 1) induces nyctinastic leaf-folding of Samanea saman. The SAR studies of 1 revealed the unique role of its glycone moiety. Biological activity and the target affinity of 1 were affected by the stereochemistry of the glycone moiety. JAG belongs to a unique class of ligands in which the structure of the glycone(More)
We developed a simple and effective method to fabricate lead oxide micro-octahedrons by electrodeposition with higher current density. The electrolyte was lead nitrate aqueous solution containing some drops of concentrated hydrochloric acid. Stainless steel plate was employed as both cathode and substrate, and graphite plate as anode. The controlled current(More)
