STMicroelectronics’ ST25TA-E NFC tag IC strengthens the security of digital product passports and blockchain-based applications by implementing state-of-the-art on-chip digital signature mechanism, TruST25 Edge. Based on elliptic curve cryptography (ECC), running on an advanced asymmetric cryptographic engine embedded in the ST25TA-E, the new on-chip signature ensures the authenticity of an attached physical object. Combining both on-chip and off-chip digital-signature mechanisms, the new ...
