Issued certificates
Issued Certificates

  • Host certificates

    • 73 certificates were issued

  • User certificates

    • 26 certificates were issued

  • SSL Server certificates

    • 1 certificate was issued

    • only for ICEPP (Univ. of Tokyo) and KEK

The 2nd APGrid PMA Meeting Meeting at Osaka Univ.


Experiences
Experiences

  • /Email field was troublesome and not available any more

    • LCG was OK

    • SRB-DSI does not work for any certificates including the field

  • Power outage because of the regular inspection of facilities requested by the government

    • Power backup by the generator was done with big efforts

    • We may stop the operation of CA for 3days in the next year

  • Securing private keys are essential for PKI operations

    • However, sometimes users copy their’s to remote sites via network and store on distributed storage systems, even on NFS servers.

    • Education is very important for users

      • Regular training should be considered

The 2nd APGrid PMA Meeting Meeting at Osaka Univ.


Plan

  • Change on CP/CPS

    • Currently, SSL server certificates are issued only for ICEPP and KEK, however, LCG needs the SSL server certificates at each LCG site

      • C=JP, O=KEK, OU=CRC, CN=FQDN

      • SSL server certificates will be issued for each site

      • General usages are forbidden and only for usage with LCG

    • We assumed that applicants are existing users of KEK Computing research center

      • Contractors in collaborating institutes cannot be a user of us

      • We will change CP/CPS to allow applications from them

        • Existing users or the persons who are endorsed by the representative of the collaborating institute of KEK

  • We will have the first audit within this year.

    • Yoshio Tanaka will be an auditor

      • Thank him for his efforts

    • November or December?

Certificate revocation
Certificate Revocation

  • Certificates are to be revoked when …

    • the RA receives a revocation request from a user.

    • the user’s key has been compromised or is suspected of being compromised.

Revocation request procedure
Revocation Request Procedure

  • Revocation Request from a user

    • User can choose between two methods, as follows:

      • Command-line UI and Web-based UI using encrypted communication between the user and the RA.

    • The RA confirms a revocation request by using the client certificate, and accepts it.

    • The RA sends a revocation request to the CA located in an independent network segment.

      • Communications between the RA and the CA are encrypted.

  • The CA security officer can execute a revocation request on behalf of the user, if it is necessary.

The 2nd APGrid PMA Meeting Meeting at Osaka Univ.


CRL

  • The KEK GRID CA will …

    • revoke the certificate immediately after receipt and acceptance of the revocation request.

    • publish the CRL on the KEK CA web site immediately.

  • A relying party can verify a certificate by retrieving the newest CRL on the web site.

  • The issued CRL is valid for 30 days.

  • The CRL will be reissued at least seven days before the previous one expires.

Physical security
Physical Security

  • CA Server :

    • dedicated machine in a locked room

      • The room is located in the secure building.

      • only connected to the RA server via an exclusive network using a private address.

      • CA server cannot be reached from the Internet.

      • CA private key :

        • Protected by a FIPS 140-2 Level 3 compliant HSM.

        • is copied in a backup device with passphrase in a key-locked shelf.

Key pair
Key Pair

  • The CA private key is generated by the HSM.

  • A user’s key pair is generated on users’ PC by using a given license ID.

    • The user’s private key is not generated by the CA and the RA.

  • Key Length:

    • CA Certificate: 2048 bits

    • End Entity: 1024 bits

  • License ID:

    • 24 characters

    • is provided from the RA for one-time authentication at the time of enrollment process of the user.
