Subject: [PATCH 2/4] esys: Shared secret calculation is not spec compliant.
|
||
|
|
|
||
|
|
Refer to specification part 1 Architecture, Section 20.1 AuditSession
|
||
|
|
Introduction: If the session was bound when created (see 19.6.10 and
|
||
|
|
19.6.12), the bind value is lost and any further use of the session for
|
||
|
|
authorization will require that the authValue be used in the HMAC.
|
||
|
|
|
||
|
|
