Chinese Data Security, Inc. (CHNDS) joins the highly visible effort by the national government in pushing for more and better Public-Key Infrastructure (PKI) in Taiwan with the TTS digital signature scheme.

TTS (Tame Transformation Signatures) is a secure, fast digital signature scheme that has been publicized at international conferences. TTS (20,28), an instance of TTS that is comparable in security to RSA-1024, can sign at one-thousandfold the speed. Its high speed and low resource requirements makes it especially suitable for low-cost smart cards.

CHNDS is sponsoring the TTS Challenge with prize money totally more than US$100,000 (about NT$3.4 million).
