Hacker-Proof-Cryptography?

They said, "their approach to online security is completely invulnerable to the main types of hacking attacks that have felled other programs in the past. “When we say proof, we mean we prove that our code can’t suffer these kinds of attacks,” said Karthik Bhargavan.

If the "main types of hacking attacks," won't work, that only means the hackers will find new "kinds of attacks" that will.

If we want secure communication, we should write a letter.

They were able to read an ancient scroll without unrolling it using laser scanning,one layer at the time,and piecing it all together using a program. It is possible to read through an envelope and the contents one layer at the time if they so desire. On the back side of personal mail there is an orange bar code. It is a code unique to that piece of mail.It allows an image of the mail piece to be tracked through the entire system. The images are stored temporarily until the mail is delivered.The keyword is temporary. Hypothetically, IF they were stored,and NOT deleted,a database could be compiled of From/To correspondents. This could be very useful information in certain cases. And very dangerous in other cases. Of course,I could be wrong.Everybody knows our government wouldn't do such a thing. This is all speculation to be sure,but a little paranoia is justified and healthy,especially in modern times.------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ https://www.wired.com/2012/03/ff-nsadatacenter/

Interesting you mentioned this. years ago, in S Africa, all overseas mail was read, both outgoing and incoming. Back in 70-80's. The telltale sign was a very neat 20mm cut along the edge on one side, where a "spoon" was installed and the entire letter read, while folded inside the envelope. Nowadays, it is simply scanned as you mention, as it goes through the mail system, packages are X-rayed in Australia and NZ and no doubt, many other countries. However, I agree i part with this idea as it captures the drugs FW idiots try to send by post, so a few screw it up for all. In Cheltenham GCHQ, UK all emails go via the Hub and screened on certain words and word use, so all is seen by others who can use your personal information, but we know they are sworn to secrecy and privacy and would never do anything untoward.============https://www.gchq-careers.co.uk/about-gchq.html

With the exception of Australia and NZ which have very strict laws, there is a lot of international travel of vegetable seeds by letter mail, and I will say from personal experience, no indication that these private letters were ever read, x-rayed or interfered with. When seeds don't germinate, as sometimes happens, people often speculate that they may have been x-rayed. It's not impossible, but there are simpler explanations.

So unless you are a criminal or a genuine threat to national security, methinks the snail mail is likely to be private enough, regardless of the technologies available to violate your privacy.

Ok,I am not a criminal,yet they collect every email,phone call,text,etc. and store it for future analysis.And yours too.And it will be stored virtually forever.With sufficient quantity of RAID assemblies,Striping,and advanced error correction, loss of one hard drive or even several is no big deal..no lost data. Stealing one or more hard drive would be useless to the thief. Check out my link in post #3 and you will see what I mean. I am not committing any crimes but I don't want someone peeping in my window 24/7,or listening in on my causal conversations. Their computers sift through Exabytes of information daily,looking for key words,and when detected,the whole conversation is marked for further analysis. A statement you made a decade ago can cost you your career. We are rapidly approaching a true Orwellian society.The foundation is being laid,and the ribbon cutting has already been done. I am sure this conversation will be flagged for future reference. Paranoid? Yes,but mainly just annoyed.

Don't forget the market for personal data, for targeted advertising, for targeted whatever. Data is a big unregulated business. The "security" data is considered especially offensive because it's the govt. and they can arrest you or otherwise mess with your freedoms (thinking of 'no fly' lists that don't require an explanation, and misapplied to people with the same unfortunate name). It concerns me even more, that private interests had equal or better opportunity to track your data and mess with you, for any reason including political reasons. With government there's always a better chance sooner or later their actions will be dragged into the light. But who is permanently under the radar, imo is really the bigger threat.

Totally invisible today is nearly impossible unless you can be totally self sufficient in all aspects.Clothing,shelter,food,fire.In a tropical climate it would be easier to survive in that manner,but winters are hard in most countries that are very far above the equator. But I do agree with you,the lone wolf is harder to detect than a pack of wolves.

Not thinking about lone, thinking about organized wolves with socially respectable covers.

Here's a corporate wolf story:

https://phys.org/news/2019-05-bayer-monsanto.html

IMHO: They are not merely wolves,they are a symbiotic merger of wolves and vultures: For instance,if you grow corn and pollen from a Monsanto hybrid blows into your field and pollinates your corn,the corn does not belong to you..it belongs to Monsanto.Likewise with fast growing pines used for pulpwood...and the list goes on.The East coast is covered in yellow pine pollen every spring.Ans corn likewise is wind pollinated.Eventually,Monsanto will own everything that grows. These cases were appealed and decided by judges in favor of Monsanto. I am not accusing anyone of anything.but an old saying comes to mind: "A good judge is one that stays paid." Corporations have got the bit between their teeth and are now in control. The mule is in the wagon,and the people are pulling it. Every piece of software has an Achilles Heel,and there are just as many smart dishonest* criminals as there are honest* criminals. Where there is a will,there is a way,or in most cases,a lawyer. Paranoid? Sure I'm paranoid,but that doesn't mean the voices are always wrong. -----------------------------------------------------------------------------           *Honest,meaning abiding by the current laws,which are made by lawyers and judges.

Hack proof today, hacked tomorrow. Some 10 year old will hack it, because he can

AFAIK The only truly unhackable communication is a one-time use code where very little actual data gets transferred.

Does that black smoke mean we have a new pope or have the barbarians crossed Hadrian's wall?

If you know the right moves, the password appears momentarily....

That is your key code to unlock the message...that must be typed into a link that is texted to your phone....that unlocks another link in the chain...

It seems that Evercrypt is a set of cryptology tools designed to counter "side-channel attacks", or hacking that exploits the defects in the implementation of cryptology code.

That some of the "side-channel attack" schemes, like variations in timing and power consumption, can actually work seems almost unbelievable...

An attempt to decode RSA key bits using power analysis. The left peak represents the CPU power variations during the step of the algorithm without multiplication, the right (broader) peak – step with multiplication, allowing an attacker to read bits 0, 1.

Wouldn't this have to assume no other operations were taking place at the time? ...seems theoretically easy, but unrealistic in the real world...or am I misunderstanding?

In the old days where text only was displayed on a monochrome CRT, I can see that it would be feasible to pick up radiation from the electron beam painting the characters on the screen. I can also believe a serial data line could radiate an intelligible signal. Beyond that, I don't see how it can be done, but that doesn't mean it can't.
