3 2008 Spring CCSDS meeting ( Washington, USA ) SMWG 3 1 . Background Interoperability test activity by participant agencies of the CCSDS to validate the Service Management was determined at a meeting of the IOAG-10 on October, JPL and JAXA agreed to develop the following prototypes based on the CCSDS Service Management(R-1) Specification and validate the effectiveness of information and procedure exchanged by the Service Management to assured and control required resources for the spacecraft mission operations. - JPL : The development of the SLE SM service-provider prototype - JAXA/Tsukuba : The development of the SLE SM service-user prototype 2. Objectives Primary Objectives - Validation of the SLE SM standard via prototyping - Demonstration of SM interoperability across JPL and JAXA. Specifically; - Validate demonstration scenario - Validate service request exchange protocol - Gain experience in application of security techniques

Interface test This test was conducted to verify the SLE-SM interface between service- provider prototype and service-user prototype. SLE-SM message exchange was handled by SMTP. In this test, the following specification and schema were applied to the service-provider prototype and the service-user prototype. -SPACE LINK EXTENSION SERVICE MANAGEMENT SERVICE SPECIFICATION (CCSDS R-1) -Service Management Schema File Set V P1 Figure 3-1Interface TEST Configuration SLESM Service-provider Prototype (CSSXP) JPL Internet JAXA/Tsukuba a SLESM Service-user Prototype (UMR-1) SLE-SM message exchanged by SMTP

6 2008 Spring CCSDS meeting ( Washington, USA ) SMWG Test tracking Test Tracking was conducted to verify the end to end interface and procedures of SLE transfer service utilization by SLE-SM Red-1 coordination. In the test tracking, JPL and JAXA used the JAXA’s “SELENE” spacecraft which is in the lunar orbit. Test tracking outline Service request was sent from the SLE-SM service-user prototype”UMR-1” at JAXA/Tsukuba to the JPL SLE-SM service-provider prototype “CSSXP”. JPL/DSN received return data from the SELENE compliant with the service request, and then transmitted these data to JAXA/Sagamihara using SLE transfer service (RAF). JAXA/Sagamihara checked the received date by the SELENE control system.

These were transferred as attached files on s using the protocol SMTP between UMR-1 and CSSXP. The rules of exchanged s are as follows: No.ItemRules 1 Subject:The following subjects are accepted.

11 2008 Spring CCSDS meeting ( Washington, USA ) SMWG Security This section shows the method of security implementation from the technical point of view, and these was based on the agreement between JAXA/Tsukuba and JPL. a. SCOPE JAXA suggested an assumption to satisfy the following items. spoofing defacing sniffing At first we considered within the range of W3C of Recommendation (red-1) appendix, based on that conditions, and we proposed the following coverage of security in the prototype. ItemsImplementContent of security Security (i.e. Encryption, Digital Signature) not applyAll parameters are to be written in the attached file, and any parameter information is not set to the mail text at all. XML Encryption Syntax and Processing applyXML is encrypted using AES128 and RSA (Ver. 1.5). The data leakage to the third person can be prevented by the encryption. As it is not possible to decrypt by the third person, the defacing and the spoofing can be prevented. The public keys are exchanged each other beforehand. XML Signature Syntax and Processing not apply XML Key Management Specification not apply Table 4-3 Implementation of Encryption

12 2008 Spring CCSDS meeting ( Washington, USA ) SMWG 12 b. IMPLEMENTATION FOR XML ENCRYPTION In the XML encryption, the following methods were used. XML data was encrypted using Symmetric Key. The encrypt key was generated by AES128 (128bit of the AES method) at every XML making. The encrypt key was wrapped by using the public key (RSA version 1.5) which were exchanged each other beforehand, and was stored in KeyInfo. The Key Encrypted Key (KEK) was mutually generated as a symmetric key beforehand. Only public keys were exchanged each other beforehand. The receiver decrypts using a private key.

Receiver 5.“KeyInfo” and “Cipher Data” were detected from received “Encrypted XML”. 6.“Encrypt Key” was decrypted by using “Private Key” from “KeyInfo”. 7.XML data was decrypted from “Cipher Data” by using “Encrypt Key”. Figure 4 ‑ 2 Process Flow of Encrypted XML data Exchange

14 2008 Spring CCSDS meeting ( Washington, USA ) SMWG 14 c. SCOPE OF XML ENCRYPTION In the XML encryption, the scope of encryption was all items excluded SleSmDocument and SleSmMessageSet. Both items of SleSmDocument and SleSmMessageSet were not encrypted in order to make the access control efficient. This section shows the samples of encryption, in which the name space and the contents of data are omitted. NOTE: Apache XML security was used in the prototype as a middleware for encryption. We encrypted in the prototype by the form that didn't omit “xenc”, because it was necessary for the name space of the encryption tag in apache XML security. The version of Apache XML security which were used in JAXA/TACC and NASA/JPL was

16 2008 Spring CCSDS meeting ( Washington, USA ) SMWG : 2) For sleSmExceptionResponse : NOTE: The sleSmExceptionResponse.unrecoginzedMessageSetResponse was not encrypted, considering the case that the receiver did not recognize the sender or the service agreement was not recognized. The sleSmExceptionResponse.invalidMessageResponse was encrypted.

17 2008 Spring CCSDS meeting ( Washington, USA ) SMWG Data Compression ATP operation went out of control by limiting data communication at JAXA since volume of the OEM, which was exchanged at ATP operation, was a large amount of data (this time it was greater than 5 Mbytes). Therefore, we conducted data compression of the OEM to reduce the data volume. This section shows the method of data compression which was used for transmission of the much volume data between JAXA/Tsukuba and JPL. a. DATA TYPE The following data was always compressed between JAXA/Tsukuba and JPL. Data Type:Trajectory Prediction Message Type:Orbit Data Message ODM Type: Orbit Ephemeris Message (OEM) File Type:Text SM operation:Add Trajectory Prediction (ATP) b. IMPLEMENTATION FOR DATA COMPRESSION JAXA/UMR-1(UM) stored the OEM text into bilateralTrajectoryData of ATP invocation. bilateralTrajectoryFormatId: ZipOEMTxt Compress: Zip Encodeing : Base64
