AH provides integrity, authentication, and non-repudiation. AH does not provide encryption which means that NO confidentiality is in place if only AH is being used. You must make use of the Encasulating Security Payload if you wish to get confidentiality.
IPSec uses two basic security protocols: Authentication Header (AH) and Encapsulation Security Payload.
AH is the authenticating protocol and the ESP is the authenticating and encrypting protocol that uses cryptographic mechanisms to provide source authentication, confidentiality and message integrity.
The modes of IPSEC, the protocols that have to be used are all negotiated using Security Association. Security Associations (SAs) can be combined into bundles to provide authentication, confidentialility and layered communication.

Storage requirements seem less critical compared to accuracy, but I guess they could still play a role in the overall effectiveness of the system.

I keep thinking about perceived intrusiveness; it seems like it could affect user acceptance, but I don't know if it's the top priority.

I think accuracy is really important for biometric systems, but I'm not entirely sure if it's the most critical characteristic.

I think the perceived intrusiveness of the system is a really important factor too. If users feel uncomfortable with the biometric technology, that could impact adoption and effectiveness. Hmm, tough choice here.

Scalability could be a key consideration, especially for large-scale deployments. But I'm not 100% sure if that's the "most critical" characteristic. Might need to revisit the course material on this.

Accuracy has to be the most important factor, right? A biometric system is useless if it can't reliably identify people. I'll go with that.

Hmm, I'm a bit unsure about this one. Is it asking about the user experience or the technical requirements? I'll have to think through the different options carefully.

This seems like a straightforward question about the key characteristics of biometric systems. I'll focus on accuracy, as that seems like the most critical factor for a reliable identification system.

Accuracy? More like 'Broom-acy'! I want my biometric system to be as precise as a professional sweeper. Anything less is just sweeping the problem under the rug.

Storage requirements are the make-or-break factor. Efficient data management is crucial for a robust biometric system.
CH

Perceived intrusiveness is the real deal-breaker. If users feel uncomfortable with the biometric process, the whole system is doomed to fail.
SA

I'd say scalability is the key factor. A biometric system needs to handle a large number of users without compromising performance.
