ABSTRACT:
Cryptographic methods and apparatus are disclosed relating to practical cryptographic systems for electronic transfer of information. Specifically, inventive techniques are described to allow the use of tamper-resistant computing devices without powerful processors; to guarantee security against criminals able to gain full control over computing devices of other parties; to allow value in privacy-protected off-line cash systems to be represented by counters instead of digital coins, without significantly compromising security against criminals who can by-pass tamper-resistance; and to allow secure currency conversion in privacy-protected off-line cash systems, without requiring tamper-resistance for receiver parties.
