Creation of a secure environment for high-rate real-time transmission of data over non-secure networks has traditionally been unable to take advantage of strong encryption methods. Without resorting to expensive parallel hardware implementation, most block-cipher algorithms are not fast enough to keep up with real-time data rates such as video transmissions. Standard stream-ciphers do not fit media streaming, since any loss of information is acceptable for video but makes the encrypted information unusable. Stream-ciphers are also breakable if used for very long information streams such as video streams.

CipherActive's patented GEAR (Global-local Encryption Accelerator Rush) technology enables the incorporation of slow and computation heavy encryption algorithm in real-time applications. GEAR is a real-time software accelerator engine, which speeds-up the encryption process of standard encryption algorithms without degrading the level of security, quality of service and lengthening networking latency.

Gear is compatible with industry standard streaming protocols such as H.323 and H.320 and does not compromise the encryption security level.

Technical Description

GEAR integrates block and stream cipher standards for secure packet transmission. Each data packet is coded individually while guaranteeing the integrity of the message and providing no possibility of losing bit stream synchronization.
