Abstract
  This paper analyses the security and efficiency of some notable privacy preserving data aggregation schemes, SP2DAS, 3PDA, and EPPA. For SP2DAS and 3PDA schemes, We show that despite the designers’ claims, there are efficient forgery attacks on the signature scheme used. We present aselective forgery ...  Read More

Volume 11, Issue 2 , July 2019, , Pages 173-183

http://dx.doi.org/10.22042/isecure.2019.165312.450

Abstract
  Detection of fake accounts on social networks is a challenging process. The previous methods in identification of fake accounts have not considered the strength of the users’ communications, hence reducing their efficiency. In this work, we are going to present a detection method based on the users’ ...  Read More

Abstract
  Authenticated encryption schemes establish both privacy and authenticity. This paper specifies a family of the dedicated authenticated encryption schemes, Artemia. It is an online nonce-based authenticated encryption scheme which supports the associated data. Artemia uses the permutation based mode, ...  Read More

7. A centralized privacy-preserving framework for online social networks

F. Raji; A. Miri; M. Davarpanah Jazi

Volume 6, Issue 1 , January 2014, , Pages 35-52

http://dx.doi.org/10.22042/isecure.2014.6.1.4

Abstract
  There are some critical privacy concerns in the current online social networks (OSNs). Users' information is disclosed to different entities that they were not supposed to access. Furthermore, the notion of friendship is inadequate in OSNs since the degree of social relationships between users dynamically ...  Read More
