Q. How do I ensure my call is secure?
A. All encryption methods use common algorithms. Security comes from the key, a number which is passed to the algorithm to tell it how to encrypt the data. A commonly employed communications encryption method is the Data Encryption Standard (DES). DES works by encrypting data with a 56-bit long key. Triple DES (3DES) is an enhancement to DES that effectively runs 112-bit long keys. DES and 3DES are both widely used in commercial and non-defense government communications today. To provide a higher degree of security than both DES and 3DES, a new standard called Advanced Encryption Standard (AES) has been developed. The new AES standard with 128-bit keys has been approved by the U.S. Government to protect sensitive, unclassified data and will replace the use of 3DES. TANDBERG supports all of the following encryption standards: AES, DES, H.233, H.234 and H.235 with an extended Diffie-Hellman key distribution on H.323, H.320 and leased lines. TANDBERG Secure Conference is on by default. This automatically generates an encrypted call. You will know that your call is secure when you see lock icons on your screen. A single lock symbol is displayed for DES. A double lock symbol is displayed for AES. Secure Conference DES and AES are both available in point-to-point calls and multipoint calls on ISDN and IP up to 768 kbps on the full TANDBERG product line. TANDBERG's implementation of the AES and DES cryptographic algorithms has been validated as conforming to Federal Information Processing Standards (FIPS) by a laboratory accredited by The National Institute of Standards and Technology (NIST).
