Mobile social network (MSN) consists of a flavor of social science and wireless communications for mobile networking. A mode to provide communication process between different nodes with similar interest's exploits MSN. Content delivery network (CDN) improves the network performance of MSN and provide quick and quite reliable applications by distributing content through some agents placed nearby the social community. MSN architecture can be modeled to provide smooth data exchange, sharing, and delivery of packets among different nodes. The fundamental working principle of architectural and protocol design is to increase the overall efficiency of the MSN in terms of end-to-end content delivering ratio, decreasing delay, and the removal of the congestion before it happens. Efficient content delivery in MSN benefits includes reduced latency for end users, less origin server load, and increased throughput. The unique characteristics of MSN belonging to social relations provide a platform for a variety of architecture and protocol design issues. This manuscript provides a comprehensive survey of MSN, particularly with respect to content distribution and designing of different protocols approaches. At first, some routing protocols and their comparison is given. Next, several approaches toward content distributions in MSN are presented. In the end, comparisons of the various methods that are based on centralized distribution approaches are given.

“…The fundamental aim of security is to protect the information and the resources against attacks and misbehavior throughout the network. In order to unify endpoint security technology and define security policies, scholars have equipped MSNs with access controls [41]- [47] as a means of classical defense. However, one cannot suffice to this method alone.…”

Abstract-Mobile social networks (MSNs) are specific types of social media which consolidate the ability of omnipresent connection for mobile users/devices to share user-centric data objects among interested users. Taking advantage of the characteristics of both social networks and opportunistic networks (OppNets), MSNs are capable of providing an efficient and effective mobile environment for users to access, share, and distribute data. However, the lack of a protective infrastructure in these networks has turned them into convenient targets for various perils. This is the main impulse why MSNs carry disparate and intricate safety concerns and embrace divergent safety challenging problems. In this paper, we aim to provide a clear categorization on safety challenges and a deep exploration over some recent solutions in MSNs. This work narrows the safety challenges and solution techniques down from OppNets and delay-tolerant networks to MSNs with the hope of covering all the work proposed around security, privacy, and trust in MSNs. To conclude, several major open research issues are discussed, and future research directions are outlined.

Access control is an important part of security that restricts the actions that users can perform on resources. Policy models specify how these restrictions are formulated in policies. Over the last decades, we have seen several such models, including role-based access control and more recently, attribute-based access control. However, these models do not take into account the relationships between users, resources and entities and their corresponding properties. This limits the expressiveness of these models. In this work, we present Entity-Based Access Control (EBAC). EBAC introduces entities as a primary concept and takes into account both attributes and relationships to evaluate policies. In addition, we present Auctoritas. Auctoritas is a authorization system that provides a practical policy language and evaluation engine for EBAC. We find that EBAC increases the expressiveness of policies and fits the application domain well. Moreover, our evaluation shows that entity-based policies described in Auctoritas can be enforced with a low policy evaluation latency.
