Mobile social networks are attractive applications which composed of a collection of different users from different countries. On that, the group of users can share personal information and stay connected with some of the users. Due to the lack of security infrastructure, the eavesdropper may intrude the conversation. In order to provide secure communication on mobile social networks an encounter-based system with Ciphertext-Policy Attribute Based Encryption (EBS-CPABE) is proposed. The proposed method provides efficient and secure communication with the proper security mechanisms. The Digital Signature Algorithm (DSA) is used for key generation. The key exchange mechanism is used to know about the authenticated users. A Ciphertext-Policy attribute-based encryption (CPABE) scheme is proposed for providing additional security as, if any server storing the data is compromised, then the confidentiality of the data will be compromised. In the proposed system for complex access control on encrypted data that we include Ciphertext-Policy Attribute-Based Encryption (CPABE). Also Tor network is built for enabling online anonymity. The performance of the proposed EBS is tested based on memory usage, execution time and delay rate. The experimental results obviously show that the proposed method performs well than the existing Encounter Based System (EBS).
