Each member of the ST1335/1336/1355 family has an identification data area, unit-counters (with an anti-tearing mechanism for reliable usage in open readers), a post validation certificate, an issuer area (ST1336) or an authentication secret key area (ST1335/1355), and a user area. This is summarized in Figure 2. The validation certificate allows the recognition of the device by the appropriate security module. The anti-tearing mechanism guards against extra, spurious count signals being executed when the |
