Security protocols on incompatible transports

A method for utilizing a transport layer security compatible with a reliable transport over an incompatible unreliable transport, the method comprising:

• providing, by a computing device, a reliability delivery layer (RDL) interface to the unreliable transport, the RDL being separated from the transport layer security and adding selected ones of data corruption detection and data loss detection to the unreliable transport and masking incompatibility of the unreliable transport without modification to the transport layer security or the unreliable transport;
• establishing, by the computing device, a communication session using the unreliable transport;
• and
• establishing, by the computing device, a secure communication session using the transport layer security over the RDL interface;
• wherein the RDL layer comprises a header including a checksum field to emulate Transmission Control Protocol (TCP) checksum used for data protection, a sequence number field and an acknowledgement field to emulate TCP data loss detection and recovery, and a flag field to facilitate TCP like connection oriented behavior management.

A method for utilizing a transport layer security over an incompatible unreliable transport, comprising:

• modifying, by a computing device, a network application program to substitute selected networking calls in the network application program to the unreliable transport with networking calls to the transport layer security;
• installing, by the computing device, a reliability delivery layer (RDL) in a network stack above the unreliable transport to masquerade the unreliable transport as a reliable transport compatible with the transport layer security without modification to the transport layer security or the unreliable transport, wherein the RDL is separated from the transport layer security;
• and
• configuring, by the computing device, the transport layer security to utilize the RDL;
• wherein the RDL layer comprises a header including a checksum field to emulate Transmission Control Protocol (TCP) checksum used for data protection, a sequence number field and an acknowledgement field to emulate TCP data loss detection and recovery, and a flag field to facilitate TCP like connection oriented behavior management.

An article comprising a non-transitory machine-accessible medium having one or more associated instructions for communicating between a first and a second machine using the User Datagram Protocol (UDP), wherein the one or more instructions, upon execution by the first machine, results in the first machine performing:

• providing a reliability delivery layer (RDL) to interface to a UDP layer on the first machine;
• establishing a UDP connection with the second machine;
• and
• establishing a transport layer security over the RDL interface to the UDP layer on the first machine;
• wherein the transport layer security is incompatible with the UDP and is separated from the RDL;
• the RDL is configured to make the UDP layer appear to be compatible with the transport layer security without modification to the transport layer security or the UDP layer;
• the RDL layer comprises a header including a checksum field to emulate Transmission Control Protocol (TCP) checksum used for data protection, a sequence number field and an acknowledgement field to emulate TCP data loss detection and recovery, and a flag field to facilitate TCP like connection oriented behavior management.
