Apple has roll out an update to iMessage encoding , the likes of which includes post - quantum protection that the company send for the “ most significant cryptographic security upgrade ” in the messenger ’s history .
In ablog postpublished Wednesday , Apple announce the arrival of PQ3 , a novel encryption communications protocol designed to gravely raise the app ’s security . Since its launch in 2011 , iMessage has offeredend - to - end encryption — which is a nice thing to have if you want to keep your chats individual . It ’s also not something everyweb messenger provides . That said , Apple ’s encryption has n’t always beenas unshakeable as you ’d need it to be . Researchers havecracked(or , at the very least , take exception ) the app ’s encryption multiple times , meaning it ’d be wise to take its past ( and , potentially , current ) assurances with a cereal of common salt .
With its latest update , Apple claims your content will now be more secure than ever been . So dependable , in fact , that the company has invented a whole unexampled level of security — what it calls “ spirit level 3”—to distinguish the unparalleled protections your iPhone conversations will now , supposedly , enjoy .

The blog state :
With via media - resilient encryption and extensive Defense against even highly advanced quantum attacks , PQ3 is the first messaging protocol to reach what we call Level 3 security system — providing communications protocol protections that surpass those in all other widely deployed messaging apps . To our knowledge , PQ3 has the strongest certificate properties of any at - scale messaging communications protocol in the world .
Apple apparently feels so confident about this assessment of unparalleled protection that it ’s supply a diagram showing how iMessage now outrank other messenger , including the popularprivacy app Signal :

In curt : This is good newsworthiness , overall . Any additional layer of protection you could add to your digital life is a win . That said , it ’s easy to receive Apple ’s new “ post - quantum ” protections sorta comic since quantum computing machine do n’t really exist yet . Indeed , while governments and magnanimous companieslike Googleare presently racingto developthem , to the full functional quantum machines have not materialized yet . Scientists seem confident that they will , finally , get in . When they do , expert contend they’lltotally upendour way of life of life , precede to breakthroughs in everything from science and medicine to mathematics .
Notably , quantum computers will likelybe able to breakcurrent public - key encryption algorithmic rule , thus unlocking much of the internet — which iscurrently protected by public - key system . There is some conjecture that quantum - relate tone-beginning are already occurring — so - call “ harvest now , decrypt later ” onset , in which a sophisticated hack may hoover up huge sum of encrypted datum in the promise of later using a quantum machine to decrypt it .
Apple ’s new protocol is designed to protect against these kinds of attack . It ’s fuel by a “ post quantum secure ” algorithm known as Kyber , which was developedby research worker associate with the National Institute for Technology and Standards ( NIST ) , the organisation that has been at the forefront of encrypted protocol development for long time . It ’s deserving noting that not all of NIST ’s post - quantum algorithmshave been foundto be secure ; that said , in general , they ’re thought to be much more dependable than current public - key system which are , themselves , pretty all-fired safe .
Apple is n’t the only one rolling out post - encryption security . Last summertime itwas reportedthat Google was working on post - quantum encoding banner to protect Chrome substance abuser from the same suppositious hackers of the time to come . Alist of other notable companieshave agreed to foster the development of alike protections in their products and chopine .
security measure experts have congratulate Apple for its iMessage update . Matthew Green , a observe secret writing professor at John Hopkins University , yell PQ3 “ very good”and said that it was a prissy improvement over Apple ’s previous courier defenses . “ You might point out that this is overkill . Quantum computer are class away , and key via media is rarefied . So why should I handle about this ? ” Greenwrote on X. “ The answer is you probably do n’t . It * is * overkill . But sometimes overkill sends a utile message , one that should be hear by people who are n’t technical at all . ”
