There can be problems with the security of social networking communications. For example, there may be occasions when a number of friends wish to communicate securely through a social network infrastructure, such that non-trusted 3rd-party entities, such as a Social Network Operator or host that provides the application infrastructure, does not overhear the communication. In response to the above problems, embodiments presented propose a set of innovative, lightweight solutions, considering that in certain scenarios the Social Network Operator may not be a trusted entity. Embodiments of the present invention are directed to methods and apparatuses for secure information sharing in social networks using random keys.
