Are Wireless Headset Conversations Secure? Headset Encryption Explained Leave a comment

The entire ranges of wireless headsets for offices (Poly/Plantronics & Jabra) offer superior security against snooping. The informal spy over hearing the radio feed shall listen to a humming noise as the audio is coded & encrypted digitally. The headset product that is wireless does not permit 2 users occupying similar feeds & time frame under usual situations as devices by themselves pick the top existing channel, while if it sense intrusion from another users then it immediately alters the feed. With events taking place in high density time slots where a better time frame & feed is not available, 2 users close to one another & occupying similar feeds & time frame could feel mutes at times due to audio being received or transmitted and at times distortion too but not some spying on audio.

Safety against planned over hearing is via user verification plus 64-bit actual digital voice recognition as per norm of accepted algorithm – EN 300 175-7. Wireless headsets made by us apply uniform accustomed frequency hopping while in idle-lock condition that while the ground & headset are within enclosed range but audio isn’t enabled. This had be done to make sure the base & headset are there to look after alteration in spectrum of radio signal taking place because of further users and there being intruders, as need for link reliability improvement, there is a additional security layer effect. The sequence of hop is not fixed, physical environment based. It is an aperiodic functioning as with such a mode instead of altering feeds at regular time intervals, the feeds are altered at times when there happens to be a fresh users attempting to connect to the same feed & creating intrusion. Where there are multiple users, there is a security coat as different users alter feeds at will instead of remaining in a constant feed.

Security for wireless headset in Bluetooth:

Headsets having Bluetooth plus adapter converse through the normal 2.4 GHz link for Bluetooth that offers digital audio that’s of high standard, distance covered up to thirty feet and improved encryption for protected communique. Plus a device verification, user permission, and encryption through voice.

The specification 1.0 for Bluetooth explains the algorithm for link encryption as a linage code having 4 linear feedback shift registers (LFSR). The breadth total derived from LFSR is 128, while spec states “the effectual key span is closeable from eight & one hundred twenty eight bits”. Via this arrangement, Bluetooth can be used in nations with laws bordering encryption power, and “assisting an upgrade in future for safeguarding sans expensive redesign of either the encryption hardware and algorithms” as per Bluetooth patterns. Important generation & verification are most likely applying eight-round SAFER+ encryption formulae. Available information suggests security through Bluetooth shall be enough for nearly all purposes.

For same reason we can conclude that Bluetooth headsets are not the best solution for secure phone calls as they can be hacked, and for the same reason the best alternative for a secure conversation on a headset will be a DECT Level C headset.

Security for wireless headset in DECT:

For desk phones with a wireless headset, Poly and Jabra offers a higher chipset wireless systems and offers a higher encryption on the frequency of the DECT wireless connectivity, this headsets are more secure and harder to be hacked while on a cyber attack, compared with the regular DECT ( Digital Enhanced Cordless Telecommunications) headset that are available on the market. Among them we have the next ones:

poly savi 7310 office wireless headset mono, deskphone and pc view

This is the next generation of wireless headset from Poly, the Savi 7310 offers the newest chipset with security step enhanced with Military level FIPS 140-2 listed. This means that the encryption of the chip is of 256 AES encryption, versus the traditional DECT encryption of 128 bit. Thanks to this the range gets increased notably versus regular wireless headsets of up to 580 feet on line of sight, another noticeable improvement on the microphone thanks to a crystal clear conversation thanks to the latest compression and modulation techniques, which means that compared with regular wireless headsets the users voice will be more clear and the other side of the call will have the best sound quality available. For same reason this unit has the Poly Acoustic Fence technology which compared with regular noise canceling microphones makes a better job for really loud environments. Thanks to the technology found in the Savi 7310, allows to deploy more headsets of the same kind in a close space, up to 2x more density when compared with regular DECT headsets without interference among them. This headset allows the use of 2 devices at the same time, desk phone and a computer.

Jabra offers the Engage 65 Stereo as a more secure wireless DECT headset thanks to the advanced shipset found on it, with this on mind a office space can deploy X3 more users in the same office space using the same headset model. For easier words to explain how this works we can say that if a office space have regular DECT wireless headsets in place would be like having the speed of a station wagon and only able to carry 3 pieces of luggage, while with the Engage chipset would be having the speed of a sports car and being able to have up to 12 pieces of luggage. The Engage has Jabra advance noise-cancelling microphone that will block most of the outdoor sounds and will only be focus on the users voice, which means the deliver crystal-clear calls even in noisy offices. This unit can be used with the desk phone and the computer, for the same reason meets Microsoft Teams Office requirements and offers a really lightweight and comfortable design with powerful speakers for a rich sound quality. The security level on the DECT frequency would considered as Security C that is the same level as a military grade frequency, making it an alternative for people wanting a wireless headset but considering the security while on a call.

Jabra offers this alternative for a computer headset with a higher encryption on the unit. Thanks to the advanced chipset found on the headset and the Link 400 this is a Level C Security wireless DECT headset. Offering a range of up to 490 feet, pretty similar as the desk phone version. With Jabra’s advanced noise-cancelling microphones similar as the desk phone counter part that makes an amazing job blocking unwanted background noises and with the lightweight headset design, making it the way to go for a secure DECT wireless headset for the computer as it is certified for Microsoft Teams and fully compatible with the Engage 65/75 bases as well.
