Common use of Registration Phase Clause in Contracts

Registration Phase. The registration phase for SMs and SPs are similar and follow the ECQV certificate scheme, refer to Section 2.3. As a result, each entity U is storing the public parameters {Ep(a,b), P, H0, H1, H2, H3, Ek(), Dk(), Ppub}, its public key Pu, certificate certU and identity IDU, together with its private key dU. Note that only the private key needs to be stored in the tamper resistant part of the memory. Similar as in the other papers in literature on key agreement schemes, we assume that the SM is also storing the public key of the SP. If not, it needs to request before the key agreement phase the identity and certificate of the SP in order to compute the corresponding public key and verify the certificate, cf. Equation (1).
