Service A carries out XML canonicalization and creates a message digest. It then encrypts the message digest using asymmetric encryption. Service B. upon receiving the message, decrypts the message hash and calculates the hash of the original message. However, upon comparison, the received message digest and the calculated message digest do not match. How can this problem be avoided?
When establishing a single sign-on mechanism, the application of the Standardized Service Contract principle requires the use of SAML because it is an industry standard understood by multiple service consumers.
Service A is a utility service that has been designed to receive and send non-confidential messages. Service A provides access to a legacy application. Since the launch of Service A . the overall usage volumes have increased beyond expectations. Upon a review of the access logs, it is discovered that most of the requests came from unauthorized service consumers. The application of the Direct Authentication and Data Confidentiality patterns will prevent this from happening in the future.
Which of the following is the primary technology used for the application of the Data Origin Authentication pattern?
The receiver of a message decrypts an encrypted message digest using the public key of the sender that corresponds to the private key. The receiver then matches it against the digest of the original message. If the decrypted digest and the newly calculated digest match, then what does it prove?
