Dynamic Support Service Selection for Business Transactions in Electronic Service Markets

Buisiness transactions in an electronic service market are expected to appear spontaneously, anonymously, and with varying requirements of infrastructural support. This support generally covers security requirements such as authentication, privacy, and public key certification as well as payment protokolls or the demand for notary services. The latter two aspects are concidered in particular in this paper. Due to the varity of ever-changing setting of such services, a flexible integration into electronic commerce infrastructures is required. This paper proposes the embedding of support services into business transactions at runtime on the basic of a CORBA DII distribution plattform. The architecturall approach is described.
