About

Dhanuja Elizabeth Thomas is a highly skilled Member of Technical Staff at Altiostar Networks, Inc. with over 8 years of relevant experience. She specializes in 5G NR protocol stack development, with expertise in interfaces such as NGAP, F1AP, E1AP, and XNAP. She has extensive experience in AKA procedures, including EAP, 5G-AKA, and 5G key generation at the UE and gNB side. She is also knowledgeable in Elliptical curve cryptographic algorithms for SUCI generation, as well as GTP and SCTP protocols. Dhanuja has completed a Master of Technology degree from Mahatma Gandhi University, Kottayam, and a Bachelor's degree in Electronics and Communications Engineering from the same university. She also has experience working with BSNL. In terms of project experience, Dhanuja has completed a 5-month internship at IIT-Hyderabad, where she worked on Secure D2D communication in LTE-A based on 3GPP standards. She also worked on IEEE 802.11s mesh networking video broadcasting on multi-hop networks and studied the performance analysis of multi-hop networks by transmitting video, audio, and background traffic at the MAC layer. In her previous role as a 5G Protocol Stack Developer at 5G Testbed IIT-Hyd, Dhanuja worked on NGAP, E1AP, F1AP, and XnAP interfaces in 5G, as well as NAS security, including 5G AKA procedures followed by key generation using HMAC. She also worked on elliptic curve cryptography, Milenage algorithm, and Rijndael algorithm, and has experience in GTP and SCTP protocols. As a Research Assistant at Indian Institute of Technology, Hyderabad, Dhanuja collected base station information of tier-2 cities in India, conducted simulations, and analyzed the impact of different user mobility models on cell residence time and MME residence time. She also extended the implementation to obtain the packet exposure ratio and number of packets received in a cellular network scenario, including D2D communication, which is prone to desynchronization attack. Dhanuja's tech stack includes software engineering, testing, and integration. She is a highly motivated and skilled professional with a proven track record of delivering high-quality work.
