True high-performance hardware based encryption/decryption on existing phone; No modification required; completely independent from phone service operators.

  • SAN FRANCISCO, California, March 1, 2010 – On the opening day of the RSA, Security Conference Expo, GOTrust Technology Inc. (GO-Trust™) announced they are delivering KingCall™, a comprehensive VoIP encryption application that uses a very special microSD (SDencrypter) containing a high-performance smart card chip and high-speed communication interfaces to protect mobile phone communication1. All the encryption and decryption is done inside the SDencrypter so it does not impact the performance of the phone and also prevents any possibilities of a Trojan virus stealing encryption keys. KingCall™ uses a microSD module loaded into unmodified 3G smart phones provided by existing phone service operators; making KingCall™ very simple and economical to deploy over a wide user base. “After GSM encryption was compromised last year2, phone users around the world have been looking for a secure alternative for their private and sensitive communications”, said Darren Lee, CEO of GO-Trust™, “once again we are first with our KingCall™ solution; incredibly powerful encryption/decryption technology for voice and text; built into a microSD. Just insert the KingCall™ microSD in existing smart phones and you are secure once more”.
