Other Approaches. Where other valuation methodologies are used, the Valuation Report should set out the rationale for using the methodologies and should contain a level of financial disclosure of such methodologies, including supporting empirical evidence, consistent with the level of financial disclosure set out herein.
Other Approaches. The NIAM language [273] is a binary relationship lan- guage, which means that relationships that involve three or more entities are not allowed. Relationships with more than two involved parts will thus have to be objecti ed (i.e. modeled as entity sets instead). In other respects, the NIAM language has many similarities with ER, although often being classi-
Other Approaches. Operators of wireless networks and participants in the dhc wg proposed alternate ways around the rogue DHCP problem. The most popular approach to deal with this problem is to enable a feature called client isolation in the wireless network. On wired networks, this feature is often called port security. This feature prohibits all direct communication between two stations in the same LAN, except for communication with the router towards the outside world. This enables users to use the internet, but protects them from any other users who are concurrently logged in. The diverted IP traffic flow in Figure 2.4 is prohibited. The Access Point will not forward an IP packet from 10.0.0.2 to 10.0.0.1 because the station that owns 10.0.0.1 is not the administratively configured router for the subnet. While this is a relatively simple countermeasure, there are drawbacks associated with it. Direct communication between stations is a requirement for some protocols (such as SIP phone calls between two handsets in the same LAN) and it may be a desired feature in some situations (such as two users who want to share a folder via Windows Networking on the same LAN). Another way to overcome the problem is to use intrusion detection systems (IDS) which actively scan the network for anomalies, for example with DHCP snooping. When such an IDS discovers a rogue DHCP server, it can trigger a disconnection of that rogue DHCP server. However, there is a drawback to this. If the DHCP announcement is inadvertent (accidental misconfiguration), the client will not get any service and will not know why.
Other Approaches. In this section we briefly discuss approaches other than Rough Volatility to the tasks of pricing and calibration. This is included to put Rough Volatility in context but will not be the focus of this thesis.
Other Approaches. Finally, more sophisticated approaches such as Policy-based Access Control, which is more focused for domains such as eGoverment and Identity Management architecture, where they organizations involved have some kind of policy and governance structure in place to ensure the successful execution of the organization’s mission, to mitigate risk, and to ensure accountability and compliance with relevant law and regulations can be considered. It is very common in public organizations, government-related bodies, banks, hospitals and critical infrastructures in general. Other approaches are defined for the presented Distributed Hash Tables, where protocols such as REsource LOcation And Discovery (RELOAD) Base Protocol defines a security model based on a certificate enrollment service that provides unique identities [74], but this is also out of the scope of the Internet of Things due to its complexity to manage credentials, and digital signatures.
Other Approaches. We briefly elaborate on two more recent approaches on beyond birthday bound secure PRP-to-PRF conversion. Xxxxxxxx and Xxxxxx [20] introduced Encrypted Xxxxxx-Xxxxx: EDMP1 ,P2 (x) = P2(P1(x) ⊕ x) , (4) where P1 and P2 are two n-bit permutations. They proved security up to around 22n/3. Xxx et al. [22] proved security of the construction up to around 23n/4 using the chi-squared method and Xxxxxxx and Xxxxx [51] proved security up to around 2n/n using the mirror theory. Mennink and Xxxxx [51] proposed its dual version Encrypted Xxxxxx-Xxxxx Dual:
