How LibOQS Uses Valgrind to Hunt for Constant-Time Leaks?In cryptography, ensuring constant-time execution is a critical defense against timing side-channel attacks. An implementation is considered constant-time if its execution time and memory access patterns are independent of secret-valued inputs. Failu...Nov 6, 2025
Can 5G SUPI Concealment really ensure Forward Secrecy?Hi there, those who don’t know me. I am Shubham, who likes to keep digging around the possibilities of any situation. Particularly, I am not limited to any tech or something ,but I am fortunate to start my journey from the farms of telecom and hope t...Jun 11, 2025
OAuth 2.0 Authorization in 5G Core Networks: Architecture, Workflows, and Security ChallengesWith the shift to service-based architecture in 5G Core, OAuth 2.0 plays a critical role in NF-to-NF authorization. However, reliance on a centralized NRF introduces security risks. Integrating Hyperledger Fabric offers a decentralized approach to en...May 22, 2025
Open RAN (O-RAN) Interoperability with xFAPIAchieving interoperability within Open RAN (O-RAN) frameworks requires robust integration between Layer 1 (L1) and Layer 2 (L2) components. xFAPI serves as an essential intermediate component, bridging these layers effectively and ensuring seamless c...Mar 27, 2025
Understanding xFAPI: Bridging L1 and L2 Layers of O-RANIn our previous blog, we explored the gaps in the MAC-PHY layer of the O-RAN interface. In this blog, we will discuss how xFAPI addresses and resolves these issues. Integrating the L1 and L2 layers of O-RAN from different vendors poses significant ch...Aug 25, 2024
Challenges in L1-L2 Interoperability within O-RANO-RAN (Open Radio Access Network) is a framework designed to emphasize interoperability and standardization, enabling baseband and radio unit components from different vendors to work together seamlessly. Despite its focus on modularity and open inte...Aug 21, 2024
RACH ProcedureRACH (Random Access Channel) — When we want to connect a UE to the 5G network, it has to synchronize in downlink as well as in uplink. Downlink synchronization is obtained after successfully decoding SSB. There are 2 types of RACH Procedures - Conten...Dec 24, 2023
