angry tapir writes: "Vodafone has developed a new SIM card that can be used on smartphones to provide secure access to data networks and tap-proof telephone calls as well as email and text message encryption. In June, Secure Login will be the first service that uses the Secure SIM, working as an alternative to traditional smart cards. When employees log into their corporate network, the SIM card and server initially exchange key data. The employee is only granted access once the card has been identified and accepted, and a PIN (personal identification number) has been entered. Vodafone will add the ability to encrypt email and phone calls. For the latter to work, both the caller and the receiver need to have a phone with Vodafone's new SIM card."
