The SDK includes sample material in example/data that is intended to be provisioned in members and verifiers so that they can operate without material from a real issuer, such as iKGF.

Sample Groups

Sample Group A

Group A (groupa) contains eight group members and sample revocation lists:

Members in Group A

Group Member	Revocation Status
groupa/member0	Non-revoked
groupa/member1	Non-revoked
groupa/privrevokedmember0	Revoked in PrivRL
groupa/privrevokedmember1	Revoked in PrivRL
groupa/privrevokedmember2	Revoked in PrivRL
groupa/sigrevokedmember0	Revoked in SigRL
groupa/sigrevokedmember1	Revoked in SigRL
groupa/sigrevokedmember2	Revoked in SigRL

Revocation Lists for Group A

Description	Directory Location	Revoked Members
Private key based revocation list	`groupa/privrl.bin`	privrevokedmember0, privrevokedmember1, privrevokedmember2
Signature based revocation list	`groupa/sigrl.bin`	sigrevokedmember0, sigrevokedmember1, sigrevokedmember2
Empty private key based revocation list	`groupa/privrl_empty.bin`	None
Empty signature based revocation list	`groupa/sigrl_empty.bin`	None

Sample Group B

Group B (groupb) contains four group members and sample revocation lists:

Members in Group B

Group Member	Revocation Status
groupb/member0	Non-revoked
groupb/member1	Non-revoked
groupb/privrevokedmember0	Revoked in PrivRL
groupb/sigrevokedmember0	Revoked in SigRL

Revocation Lists for Group B

Description	Directory Location	Revoked Members
Private key based revocation list	`groupb/privrl.bin`	privrevokedmember0
Signature based revocation list	`groupb/sigrl.bin`	sigrevokedmember0
Empty private key based revocation list	`groupb/privrl_empty.bin`	None
Empty signature based revocation list	`groupb/sigrl_empty.bin`	None

Group Revocation Lists

If an entire group is no longer valid, the issuer can revoke it using the group revocation list. Two sample group revocation lists are provided with the SDK.

Sample GrpRLs

Group Revocation List	Description
`grprl_empty.bin`	No entries
`grprl.bin`	One entry in which `groupb` is revoked

Compressed Sample Groups

Intel® EPID SDK supports use of compressed member private keys. The groups described here use compressed member private keys but structurally correspond to groups described above.
