Mobile and telecommunication networking uses temporary and random identifiers (IDs) to protect user privacy. For greater intelligence and security o the communications between the core network and the mobile user, we design and build a dynamic randomization scheme for the temporary IDs for mobile networking, including 5G and 6G. Our work for ID randomization (ID-RZ) advances the existing state-of-the-art ID re-allocation approach in 5G in the following ways. First, ID-RZ for ID updates is based on computing, as opposed to incurring networking for the re-allocation-based updates, and is designed for lightweight and low-latency mobile systems. Second, ID-RZ changes IDs proactively (as opposed to updating based on explicit networking event triggers) and provides stronger security (by increasing the randomness and frequency of ID updates). We build on the standard cryptographic primitives for security (e.g., hash) and implement our dynamic randomization scheme in the 5G networking protocol to validate its design purposes, which include time efficiency (two to four orders of magnitude quicker than the re-allocation approach) and appropriateness for mobile applications.

WRKY transcription factors (TFs) act in regulating plant growth and development as well as in response to different stress. Some earlier studies done by individual researchers reported different wheat WRKY TFs. Although, the recently released wheat genome has opened an avenue to investigate wheat WRKYs (TaWRKY) TFs. Prime objective of this study to performed genome-wide classifications of TaWRKYs and their functional annotation. The classification of 107 individual identified characterized sequences of TaWRKY (IICS-TaWRKY) and 160 uncharacterized draft sequences of TaWRKY (UDS-TaWRKY), along with their gene structures and motifs analysis was performed. Along with comparative sequence analysis and microarray analysis was performed to mimic out TaWRKYs functions in response to different abiotic stresses, accompanied by in-vitro validation. The comparative phylogenetic analysis and estimation of Ka/Ks ratio with Triticum urartu, illustrate group based clasifications of TaWRKYs and evolutionary divergences. Furthermore, motif-based and protein-DNA interaction analysis of TaWRKYs helps to identify, their putative function in target DNA recognition sites. Subsequently, results of microarray and comparative sequence analysis provides the evidence of TaWRKYs involved in heat and/or drought stress. Further, in-vitro results validates that TaWRKY014, TaWRKY090 are found to participate in response of drought stress, whereas TaWRKY008, TaWRKY122, and WRKY45 are involved in response of heat and drought stress. These findings can be utilized in developing novel heat and drought-tolerant wheat cultivars using marker-assisted breeding and transgenic development.
