The present document lists cryptographic suites used for the creation and validation of digital signatures and electronic time stamps and related certificates. The present document builds on the agreed cryptographic mechanisms from SOG-IS [15]. It may be used also for electronic registered delivery services in the future The present document focuses on interoperability issues and does not duplicate security considerations given by other standardization bodies@ security agencies or supervisory authorities of the Member States. It instead provides guidance on the selection of concrete cryptographic suites that use agreed mechanisms. The use of SOG-IS agreed mechanisms is meant to help ensure a high level of security in the recommended cryptographic suites@ while the focus on specific suites of mechanisms is meant to increase interoperability and simplify design choices. There is no normative requirement on selection among the alternatives for cryptographic suites given here but for all of them normative requirements apply to ensure security and interoperability The present document also provides guidance on hash functions@ (digital) signature schemes and (digital) signature suites to be used with the data structures used in the context of digital signatures and seals. For each data structure@ the set of algorithms to be used is specified.
