Online Certificate Status Protocol (OCSP) based services provide online certificate revocation checking. However, these types of services can introduce network latency because only one certificate can be checked at a time.
A hash is created as a result of carrying out a digest function. The hash is subsequently used together with XML canonicalization functions to match message documents in order to prove integrity and authenticity.
The communication between Service A and Service B needs to be kept private. A security specialist is planning to implement secret key cryptography in order to encrypt the messages. Which of the following approaches addresses this requirement?
XML canonicalization is the process of standardizing the syntax of XML documents that are to be digitally signed. This way, when the digital signature is verified, it reproduces the same message digest for assessing message integrity.
