“The design decision referenced in The Guardian story prevents millions of mesغير مجاز مي باشدes from being lost, and WhatsApp offers people security notifications to alert them to potential security risks,” the company added.What is interesting to note is that the Signal private mesغير مجاز مي باشدing app unlike WhatsApp, isn’t vulnerable to the same attack. On the contrary, WhatsApp will send that mesغير مجاز مي باشدe anyway.WhatsApp’s end-to-end encryption relies on a set of keys that verify whether the sender and the receiver are, who they claim to be.WhatsApp further clarified stating that the company has even published a technical white paper of its encryption design. However, The Guardian piece describes a believable attack that WhatsApp’s given encryption system cannot stop. But the receiver’s encryption key will change if the app is re-installed, the handset is replaced or there is a change of mobile number.Photo credit: Open Whispers SystemIn other words, if an attacker gained access to a WhatsApp server, he/she could forcibly reset the keys used to encrypt mesغير مجاز مي باشدes and install himself as the user thereby gaining access to the future mesغير مجاز مي باشدes exchanged between parties.“If WhatsApp is asked by a government agency to disclose its mesغير مجاز مي باشدing records, it can effectively grant access due to the change of keys,” Boelter said. WhatsApp gives users the option to be notified when those changes occur. But the receiver’s encryption key will change if the app is re-installed, the handset is replaced or there is a change of mobile number. But just like any tech it’s not perfect.However, WhatsApp rebutted these accusations.

The Guardian posted an article earlier this week which left majority of the WhatsApp users in a state of panic. (Photo credit: Open Whisper System)The catch here is that the sender is notified of the key change only if the ‘Key Change Notification’ feature is on. In such cases, WhatsApp generates a new key for that user. Any attempt to intercept mesغير مجاز مي باشدes in transmit by the server is detectable by the sender, just like with Signal, PGP, or any other end-to-end encrypted communication system,” Marlinspike said.What is he really referring to?WhatsApp’s end-to-end encryption essentially relies on the generation of unique keys.WhatsApp’s backdoor issue, not really an issueMoxie Marlinspike, founder of Open Whisper Systems in contrast to The Guardian piece states, “This is something any public key cryptography system has to deal with. Once the mesغير مجاز مي باشدe is re-sent, the sender is notified of the receiver’s key change.At the same time, American digital rights group, Electronic Frontier Foundation said Jonathan Zdziarski, a leading independent security researcher and forensics expert.The report quoted cryptography and security researcher at the University of California Tobias Boelter as claiming that due to a given “security vulnerability,” Facebook-owned WhatsApp could intercept and read encrypted mesغير مجاز مي باشدes that the users exchanged on the app.

The chatting app also offers users an added layer of verification through options like ‘Safety Number’ or ‘Security Code’ that both the parties can visually check and verify Combined Grinding Machine to know if they are using the same security code. In the case of former, when the client detects a new key, it will block the mesغير مجاز مي باشدe rather than risk sending it across, unsecured. The chatting app has been transparent about the government’s requests it receives, publishing data about these requests in the ‘Facebook Government Requests Reports. Privacy campaigners feel that this vulnerability is a huge threat to freedom of speech and warned that it could even be used by government agencies as a “backdoor” to snoop on users. During this time the sender’s encrypted mesغير مجاز مي باشدes are in a state of void, waiting to be re-sent.” “The fact that WhatsApp handles key changes is not a ‘backdoor,’ it is how cryptography works.He further states that the only reasonable question to ask in this scenario is whether WhatsApp should just delete mesغير مجاز مي باشدes in transit or hold them until a new key is generated. “No question about it, this is good tech. This is done with the help of a Signal protocol developed by Open Whispers System, that is traded and verified between users to guarantee communications are secure and cannot be intercepted by a middleman.’So where does the issue really lie?WhatsApp’s end-to-end encryption relies on a set of keys that verify whether the sender and the receiver are, who they claim to be.”. In a statement WhatsApp said that it would fight any government request to create a backdoor
