Patent attributes
Embodiments include apparatuses, methods, and systems for managing security of a communication network. A message, formatted based on a stateless communication protocol for a communication network, may be received from a first computing device and by a second computing device. The second computing device generates and further stores, based on a hash function stored in a storage device associated with the second computing device, a fingerprint of the message. The fingerprint is generated using the hash function based on at least a portion of a header of the message or a portion of a body of the message. In addition, the second computing device detects whether the generated fingerprint of the message has a duplicated fingerprint already stored in the storage device, where the message is a retried message or replayed message of a message having the duplicated fingerprint. Other embodiments may also be described and claimed.
