With the proliferation of sophisticated attacks against communication and information systems, existing protection mechanisms are becoming inefficient to guarantee an acceptable security level. Hence, new security techniques are being developed to keep up with the evolution of threats and exploits. One of the security issues that is being investigated by the research community is per-packet authentication, where security mechanisms should be implemented to enforce the authentication of a specific network flow. This paper mainly focuses on the use of biometric techniques since they offer a promising potential to enforce per-packet authentication policies in highly dynamic contexts. We provide a review of how biometrics have been proposed in the literature as an alternative to purely cryptographic mechanisms for per-packet authentication. The drawbacks of the existing are pointed out and discussed. We finally explore the research niches that will shape the evolution of this field in the near future.
