This paper describes the security architecture that applies to the interbank settlement network and should be viewed in the context of the publication: Interbank Settlement Network, (Position Paper number: 02/2008), which describes the architectural design of the interbank settlement network component of the interbank settlement system. SWIFT has recently implemented a new security solution based on a Public Key Infrastructure (PKI).
