Exponentiation Exponentiation is conducted in an elliptic curve cryptosystem, whose default parameter values are specified in ISO/IEC 14888-3 [4]. Signature Systems The user uses an elliptic curve based AMV-signature system, as specified in ISO/IEC 14888-3 [4], in order to generate signatures. The TTP may use both an AMV-signature system, as specified in ISO/IEC 14888-3 [4], and an RSA-signature sy Encryption Systems The symmetric encryption system used in the trial is DES in CBC mode [16, 17]. Parameter T The parameter T represents the maximum number of micropayment tokens which can be transferred with respect to a given signed commitment. The default value for T is 210. 8.2 The ASPeCT Secure Billing Trial 9 Conclusions References Back matter This book consitutes the refereed proceedings of the 5th International Conference on Intelligence in Services and Networks, IS & N'98 in Antwerp, Belgium, in May 1998.
