Description

There are 2 groups

• groupa

• groupb

Note: No compressed key sample material is included in this folder.

Group A

groupa contains 8 members. Each member has a member private key mprivkey.dat. Here are the members:

• member0 - a member in good standing

• member1 - a member in good standing

• privrevokedmember0 - a member revoked using its private key

• privrevokedmember1 - a member revoked using its private key

• privrevokedmember2 - a member revoked using its private key

• sigrevokedmember0 - a member revoked using a signature

• sigrevokedmember1 - a member revoked using a signature

• sigrevokedmember2 - a member revoked using a signature

In addition, groupa contain the following revocation lists:

• pubkey.bin - group public key

• privrl.bin - private key based revocation list with 3 entries - privrevokedmember0, privrevokedmember1 and privrevokedmember2

• sigrl.bin - signature based revocation list with 3 entries - sigrevokedmember0, sigrevokedmember2 and sigrevokedmember2

• privrl_empty.bin - private key based revocation list with 0 entries

• sigrl_empty.bin - signature based revocation list with 0 entries

Group B

groupb contains 3 members. Each member has a member private key mprivkey.dat. Here are the members:

• member0 - a member in good standing

• privrevokedmember0 - a member whose private key is revoked

• sigrevokedmember0 - a member whose signature is revoked

In addition, groupb contain the following revocation lists:

• pubkey.bin - group public key

• privrl.bin - private key based revocation list with 1 entry - privrevokedmember0

• sigrl.bin - signature based revocation list with 1 entries - sigrevokedmember0

• privrl_empty.bin - private key based revocation list with 0 entries

• sigrl_empty.bin - signature based revocation list with 0 entries

Default files

• /data/cacert.bin - CA certificate used as default input to signmsg and verifysig

• /data/grprl.bin - group revocation list with one entry groupb used as default input to verifysig

• /data/pubkey.bin - public key in groupa used as default input to signmsg and verifysig

• /data/mprivkey.dat - private key of a member0 in the groupa used as default input to signmsg

• /data/privrl.bin - private key based revocation list in the groupa with 0 entries used as default input to verifysig

• /data/sigrl.bin - signature based revocation list in the groupa with 0 entries used as default input to signmsg and verifysig

Group revocation lists

There are 2 group revocation lists:

• grprl.bin - group revocation list with 1 entry - groupb

• grprl_empty.bin - group revocation list with 0 entries
