Techniques for flow control packet processing

Techniques and apparatuses for processing data unit are described. In one embodiment, for example, an apparatus for networking may include at least one memory, logic, at least a portion of the logic comprised in hardware coupled to the at least one memory, the logic to access an encrypted packet having an encrypted portion, determine at least one flow control segment of the encrypted portion, decrypt the at least one flow control segment to generate a partially-decrypted packet comprising a decrypted at least one flow control segment and an encrypted remainder portion, the remainder portion comprising a portion of the encrypted packet that does not include the decrypted at least one flow control segment, access process information in the decrypted at least one flow control segment, and process the partially-decrypted packet according to the process information. Other embodiments are described and claimed.
