Recently i became involved in project of designing semi-custom VLSI device for endecryption. The device uses variable length RSA for key exchange and IDEA for data encryption. For pipelinig IDEA block we have to use 6 multipliers 16 bit ant that leaves us with 96 bit adder for RSA calculations. ( The chip should be reasonably cheap ). Otherwise the RSA speed would not
As this is in Estonia, I don't suppose you're bothered about the patents? As far as I know, RSA/PKP patents are for _algorithms_, not respected outside the US, though patents for RSA/PKP _hardware_ would be respected worldwide. I'm not sure how algorithm patents can be applied to hardware -- you may or may not be able to sell this chip in the US _without_ violating patents. (Though you can freely sell RSA hardware or software outside the US.) You may even be able to apply for a European patent for the hardware, which would then be respected everywhere, except in the US where it may be superceded by the algorithm patents. -------------------------------------------------------------------------- Rishab Aiyer Ghosh rishab@dxm.ernet.in Voicemail +91 11 3760335; Vox/Fax/Data 6853410 H-34C Saket New Delhi 110017 INDIA The National Fairness to Game Animals Association says: Support your right to arm bears! --------------------------------------------------------------------------
