Overview

The chip is intended for use in passive UHF transponder applications. IC derives its operating power from an RF electromagnetic field generated by a reader, which is received and rectified by the chip. The chip sends the answer back to the reader using a backscatter modulation technique. NT1025_4E4 provides a fast and flexible anti-collision protocol based on internal random number generator according to EPC standard. NT1025_4E4 supports all EPC C1G2 mandatory commands. NT1025_4E4 has a 480 bit EEPROM organized in 4 banks. NT1025_4E4 provides an authentication procedure based on the GOST 28147-89 cryptographic algorithm. For implementation of the algorithm, an additional 128-bit nonvolatile memory bank is used to store a secret key (Key128).

Root of Trust: A Security Essential for Cyber Defense

Imagine a datacenter powering critical cloud services, silently compromised by a tampered chip inserted during manufacturing. In most cases, the malware would be practically impossible to remove and could persist across formats/reinstalls !

Why Hardware Root of Trust Needs Anti-Tampering Design

The hardware root of trust (HRoT) provides the trust base (root key), hardware identifier (UID), hardware unique key (HUK), and entropy required for the secure operation of the entire chip and therefore is often the focus of hacker attacks. If the design can’t effectively resist attacks, hackers can easily obtain the secrets of the entire chip. Attackers can use the secrets to crack identity authentication and data encryption and steal product design know-how, causing application security problems.
