CCA Release 2.54

00 03 The number of bytes of data in the access-control points for this

segment. There are 3 bytes, for the access-control points from 512

through 535.

00 00 A reserved field, which must be filled with zeros.

8F 99 FE This is the second set of access-control points, with one bit

corresponding to each point. Thus, the first byte contains bits 512-519,

the second byte contains 520-527, and the third byte contains 528-535.

Figure B-44. Role Data Structure

This structure contains the following data fields.

00 01 The role structure version number.

00 62 The length of the role structure, including the length field itself.

“*New default role 1*” The 20 character comment describing this role.

AB CD The checksum for the role.

Note: The checksum value is not used. In future versions of the role

structure, the checksum may be verified in the Cryptographic

Coprocessor.

00 00 A reserved field, which must be filled with zeros.

“DEFAULT ” The Role ID for this role. The role in this example will replace the

DEFAULT role.

23 45 The Required Authentication Strength field

01 0F The lower time limit. X'01' is the hour, and X'0F' is the minute

(decimal 15), so the lower time limit is 1:15 AM, GMT.

17 1E The upper time limit. X'17' is the hour (decimal 23), and X'1E' is the

minute (30), so the upper time limit is 23:30 GMT.

7C This byte maps the valid days of the week for the role. The first bit

represents Sunday, the second represents Monday, and so on. Hex 7C

is binary 01111100, and enables the weekdays Monday through Friday.

00 This byte is a reserved field, and must be zero.

Access-control-point list The remainder of the role structure contains the

Access-Control-Point list described above.
