Dynamic Linkability with User Authentication Privacy Preserving for Roaming Services
The roaming service communication is difficult part to one network to another network. The main server having all services for provides or communicates to other. While during this communication users must secured the data or its privacy preserve. Hence the authors propose to strong smart gateway for both network to user authentication very efficiently and doing its services very easily with efficiently hide users identities and for security they are applying AES algorithm is good result compare to exiting system i.e. Novel Group Signature Technique (NGST) in Conditional Privacy-preserving Authentication with access Linkability (CPAL).
