Such distribution can cause economic harm to the content's copyright owner and others. Our protocol, SPIES, allows one party to sell a secret to second party and provides an economic incentive for two parties to limit sharing of a secret between themselves. We do not use watermarking or traditional DRM mechanisms. We focus on content which is to be shared between two parties only, which is valuable, and which only needs to be protected for a limited amount of time. Examples include passwords to a subscription service, pre-release of media for review, or content shared but bound by a non-disclosure agreement. With SPIES, any possesor of the content can receive a portion of the funds placed in escrow by the two legitimate possesors. We analyze this system and show that the best strategy of the content provider and content consumer to maximize their utility is to use SPIES and not share the content further. We deal successfully with a ``dummy registration'' attack in which multiple false identities are used in an attempt to get a higher payment.

The key to improving performance in DTNs is to engineer a greater number of transfer opportunities. We earlier proposed the use of throwbox nodes, which are stationary, battery powered nodes with storage and processing, to enhance the capacity of DTNs. However, the use of throwboxes without efficient power management is minimally effective. If the nodes are too liberal with their energy consumption, they will fail prematurely. However if they are too conservative, they may miss important transfer opportunities, hence increasing lifetime without improving performance. In this paper, we present a hardware and software architecture for energy efficient throwboxes in DTNs. We propose a hardware platform that uses a multi-tiered, multi-radio, scalable, solar powered platform. The throwbox employs an approximate heuristic for solving the NP-Hard problem of meeting an average power constraint while maximizing the number of bytes forwarded by it. We built and deployed prototype throwboxes in UMassDieselNet -- a bus DTN testbed. Through extensive trace-driven simulations and prototype deployment we show that a single throwbox with a 270 cm2 solar panel can run perpetually while improving packet delivery by 37\% and reducing message delivery latency by at least 10\% in the network.", journal = "IEEE/ACM Transactions on Networking", keywords = "Power Management; DTN; Journal Paper; DOME", month = "April", number = "2", pages = "554--567", sponsors = "CNS-0447877, NSF-0133055, CNS-0520729, CNS-0519881, DUE-0416863", title = "{Design and Field Experimentation of an Energy-Efficient Architecture for DTN Throwboxes}", url = "http://forensics.umass.edu/pubs/Banerjee.ToN.2010.pdf", volume = "18", year = "2010", bdsk-url-1 = "http://forensics.umass.edu/pubs/Banerjee.ToN.2010.pdf", }

Just as in traditional networks, malicious nodes within a DTN may attempt to delay or destroy data in transit to its destination. Such attacks include dropping data, flooding the network with extra messages, corrupting routing tables, and counterfeiting network acknowledgments. Many existing methods for securing routing protocols require authentication supported by mechanisms such as a public key infrastructure, which is difficult to deploy and operate in a DTN, where connectivity is sporadic. Furthermore, the complexity of such mechanisms may dissuade node participation so strongly that potential attacker impacts are dwarfed by the loss of contributing participants. In this paper, we use connectivity traces from our UMass DieselNet project and the Haggle project to quantify routing attack effectiveness on a DTN that lacks security. We introduce plausible attackers and attack modalities and provide complexity results for the strongest of attackers. We show that the same routing with packet replication used to provide robustness in the face of unpredictable mobility allows the network to gracefully survive attacks. In the case of the most effective attack, acknowledgment counterfeiting, we show a straightforward defense that uses cryptographic hashes but not a central authority. We conclude that disruption-tolerant networks are extremely robust to attack; in our trace-driven evaluations, an attacker that has compromised 30\% of all nodes reduces delivery rates from 70\% to 55\%, and to 20\% with knowledge of future events.

As buses travel their routes, they encounter other buses and in some cases are able to establish pair-wise connections and transfer data between them. We analyze these traces to characterize inter-contact behavior among buses, and study the impact on DTN routing performance. We find that the all-bus-pairs aggregated inter-contact times show no discernible pattern. However, the inter-contact times aggregated at a route level exhibit periodic behavior. By analyzing the deterministic inter-meeting times for bus pairs on different route pairs, and then additionally considering variability in bus movement and random failures to establish connections when a pair of buses are in transmission range, we find that these inter-contact times aggregated at a route level can be modeled as mixtures of normal distributions. Based on this analysis, we construct generative models that capture the behavior described above, allowing one to generate synthetic traces of DTN inter-contact times. Using trace-driven simulations of epidemic DTN routing, we find that the epidemic performance predicted by traces generated with this finer-grained route-level model are much closer to the actual performance that would be realized in the operational system than traces generated using the coarse-grained all-bus-pairs aggregated model.

We earlier proposed the use of throwbox nodes, which are stationary, battery powered nodes with storage and processing, to enhance the capacity of DTNs. However, the use of throwboxes without efficient power management is minimally effective. If the nodes are too liberal with their energy consumption, they will fail prematurely. However if they are too conservative, they may miss important transfer opportunities, hence increasing lifetime without improving performance. In this paper, we present a hardware and software architecture for energy efficient throwboxes in DTNs. We propose a hardware platform that uses a multi-tiered, multi-radio, scalable, solar powered platform. The throwbox employs an approximate heuristic for solving the NP-Hard problem of meeting an average power constraint while maximizing the number of bytes forwarded by it.

Bluetooth's half-duplex process of neighbor discovery can take tens of seconds to complete between two mutually undiscovered radios. This delay can be larger than the time that mobile nodes can be expected to remain in range, resulting in a missed opportunity and lower overall performance in a DTN. This paper proposes a simple, cost effective, and high performance modification to mobile nodes to dramatically reduce this delay: the addition of a second Bluetooth radio.

MaxProp is based on prioritizing both the schedule of packets transmitted to other peers and the schedule of packets to be dropped. These priorities are based on the path likelihoods to peers according to historical data and also on several complementary mechanisms, including acknowledgments, a head-start for new packets, and lists of previous intermediaries. Our evaluations show that MaxProp performs better than protocols that have access to an oracle that knows the schedule of meetings between peers.

Later, candidate encrypted streams are compared against these profiles. In our evaluations using real traffic, we find that many web sites are sub ject to this attack. With a training period of 24 hours and a 1 hour delay afterwards, the attack achieves only 23\% accuracy. However, an attacker can easily pre-determine which of trained sites are easily identifiable. Accordingly, against 25 such sites, the attack achieves 40\% accuracy; with three guesses, the attack achieves 100\% accuracy for our data. Longer delays after training decrease accuracy, but not substantially. We also propose some countermeasures and improvements to our current method.

Although nodes contact only direct neighbors (who change frequently) and do not use any ad hoc routing, the system maintains good IR performance. This makes our design applicable to mobility situations where routing partitions are common. Our evaluation shows that our scheme provides significant savings in network costs, and increased access to information over ad-hoc routing-based approaches; nodes in our system require only a modest amount of additional storage on average.", booktitle = "Proc.

The problem of selecting a good data source is difficult because some peers may not be encountered more than once, and many peers are on low-bandwidth connections. Despite these facts, information obtained about peers just prior to the download can help guide peer selection. A client can gain additional time savings by aborting bad download attempts until an acceptable peer is discovered. We denote as peer selection the entire process of switching among peers and finally settling on one. Our main contribution is to use the methodology of machine learning for the construction of good peer selection strategies from past experience. Decision tree learning is used for rating peers based on low-cost information, and Markov decision processes are used for deriving a policy for switching among peers. Preliminary results with the Gnutella network demonstrate the promise of this approach.", booktitle = "Proc. Intl.

Our analysis indicates that the locality of files is skewed in all four cases and fits well to a log-quadratic distribution. This predicts that caches of the most popular songs would increase performance of the system. We also took baseline measurements of file types and sizes for comparison over time with future studies. Not surprisingly, audio files are most popular, however a significant fraction of stored data is occupied by videos. Finally, we measured the distribution of time peers in Gnutella were available for downloading.
