Cellcrypt is the leading provider of technology to secure mobile voice calls on everyday smartphones. Consumers, governments and corporate enterprises use its flagship product - Cellcrypt Mobile™ - worldwide.
Founded in 2005, Cellcrypt's R&D innovation resulted in Encrypted Mobile Content Protocol (EMCP), an Internet Protocol (IP) based technology that optimises delivery of encrypted data between mobile devices over wireless networks. EMCP solves the technical challenge of delivering reliable high-performance encryption of voice data over networks with low bandwidth and varying connectivity.
Cellcrypt technology operates over data-enabled networks including 2G (GPRS/EDGE), 3G (HSPA, CDMA/EV-DO), Wi-Fi® and satellite, and are optimised to run on Nokia® Symbian and BlackBerry® smartphones.
Deployment
Cellcrypt solves the significant technical challenge of delivering strong encryption across mobile networks whilst maintaining high performance phone call attributes: by using Encrypted Mobile Content Protocol (EMCP) on the data channel, and a powerful secure central switch.
Security
Cellcrypt's solution addresses security on multiple levels and establishes an encrypted call between trusted devices. Cellcrypt’s products are undergoing certification to FIPS 140-2 standard, approved by the US National Institute of Standards & Technology (NIST).
Key Generation: A unique private key is generated on the user handset during the installation to identify the device. No other copy exists on another device or server.
Trust Management: Each phone has a phonebook of trusted numbers and their associated pubic key without the need for a central server or certificate authority.
Key Exchange: when making or receiving a secure call, the encryption engine authenticates the other party and generates a unique session key that lasts only for the duration of the call.
Signalling Encryption: signalling information that sets up a voice call is encrypted to prevent an eavesdropper from gathering information on the phone number and identity of the participants of a conversation.
Voice Encryption: end-to-end security is enabled because only trusted mobile phones at each end of the secure call perform cryptography
