How secure are wireless business telephones using DES Encryption? - Heather T I'm looking for wireless telephones for my business that use a VERY secure encryption. The one that was quoted by our local telephone company uses DES encryption. Is this really that secure? If not does anyone know a company that does carry a more secure product at a decent price? Our company does use a Nortel VoIP system and we are looking to expand with wireless sets that work with our BCM. Securely.

Best Answer: DES, Digital Encryption Standard, is no longer considered to be a secure form of encryption. It uses a 56 bit key size that is now considered too short. There were also concerns about a back-door in it. Triple DES was created and is considered secure. AES, or Advanced Encyrption Standard, is the latest encryption.
