Mar. 26, 2026 –

TES Electronic Solutions GmbH unveils a next-generation VHDL-based ECDSA (Elliptic Curve Digital Signature Algorithm) IP core, designed to deliver high-performance, secure, and energy-efficient cryptographic processing for modern embedded systems. The IP is designed for elliptic curve cryptography (ECC) using the ANSI X9.63 secp256k1 Koblitz curve and can be integrated into a wide range of applications and target technologies.

Key Benefits

• Full ECDSA Implementation: Compliant with Standards for Efficient Cryptography (SEC), including ANSI X9.63 and secp256k1 Koblitz curve which is the same curve used by Bitcoin.
• Timing-Secure Design: Ensures execution time is independent of secret keys, eliminating timing-based side-channel attacks.
• Hardware-Defined Cryptographic Core: Built with a customizable, software-defined 256-bit architecture, allowing flexibility for future protocol updates.
• Flexible Functionality: Supports essential ECDSA operations such as:
  • gfp_keygen: Key generation over prime fields (GF(p)) in an elliptic curve cryptography. It produces a private–public key pair.
  • gfp_sign_genius: Function for signature generation over GF(p) - i.e., creating a digital signature using an ECC private key.
  • pkeyutl: A single command using openssl pkeyutl to create an ECDSA signature with an EC private key over a given input message using a chosen digest algorithm.
  • dgst_sha256_sign: A single command that uses openssl dgst with SHA-256 to create a digital signature of a given input message using an EC private key.
• TES can easily expand its IP to include additional functionality in the field of cryptography, creating new opportunities for advanced security features and scalable protection solutions.
