A new security service for future military messaging

Messaging service still remains fundamental for military operations. This service is an important tool to fulfill missions, either in time of peace or in time of crisis. Military operational needs must comply with specific requirements. Military standards describe the services that meet these needs. For different reasons, current military messaging standards became obsolete and the definition of new military standards has become necessary. Studies have shown that it is possible to rely on Internet standards to design a new military messaging system but some services may not be covered by these standards, for example, securing a military message involves defining new security mechanism. This paper presents the design of an extension of the S/MIME standard that meets the security requirements applicable to military messages.
