encrypted simcard going to be available in india in future

The government of India is allowing the use of proxy SIM cards carrying digital certificates for mobile phones to allow secure communication over SMSes and email. Currently, impersonating an email address is allegedly easy by downloading software available on the internet. However, these digital certificates will attempt a degree of authentication on mobile communication. 

Sim cards will come with digital signatures for safer communicating 

This is especially important because mobile banking and net banking on the mobile phone is picking up pace.  To make India's future in mobile banking and mobile transactions secure, we are recommending the certification of proxy SIM cards with digital certificates, which can be inserted on top of regular SIM cards. These will enable the signatures with emails and even SMSes sent via mobile phones," said N Vijayaditya, Controller of Certifying Authority.
