Collaborate Disseminate
Suppose a setting similar to Yao’s Millionaire Problem, but with a third party: Multiple users of a (semi-trusted) cloud platform, each in possession of one natural number in the range between 1 and 1,000,000 (for instance), want to secure… Continue reading Secure integer comparison with third party without homomorphic encryption [migrated]
I am looking into ways to build a data warehouse that would house confidential data for 1+ clients. The requirement is that our organization can never obtain access to the decrypted data. There would be a web application clients utilize to… Continue reading Confidential Computing – SQL Server Always Encrypted w/ Secure Enclave – Customer Managed Keys or alternative
I need some serious suggestions on my protocol, specifically for decryption.
So the scenario is Organizations A and B encrypt their employees’ records with their respective public keys and store them in a distributed blockchain.
When a Use… Continue reading Non-interactive multi key encryption and decryption
Hello I had used this pgp public key on my win10 OS with pgptool to message someone.
Then when i used that same public key in whonix OS console it came back with some type of warning about malicious item that could go into root?
SO i didnt… Continue reading PGP public key flagged as malicious to root. Was ran before
I’m not sure if I have my terminology right here or that my question is accurate, I will expound here:
Homomorphic encryption seems to be impractical but from my limited knowledge looks like the only area that fully secures all data.
The c… Continue reading Is state management of deciphered data a security risk?
if using more two or more encryption algorithms together how do we compute the strength of the final encryption?
And how would the application on quantum computers
the first two tables I believe to be true/correct – is that correct?
the th… Continue reading if using more two or more encryption algorithms together how do we compute the strength of the final encryption?
As you may already know, there’s a lot of data out there, and some of it could actually be pretty useful. But privacy and security considerations often put strict limitations on how it can be used or analyzed. DataFleets promises a new approach by which databases can be safely accessed and analyzed without the possibility […] Continue reading DataFleets keeps private data useful, and useful data private, with federated learning and $4.5M seed
Im reading about FHE and the libraries implementing it (SEAL, HELib).
I saw that SEAL doesn’t support bitwise operations but I wondered if its theoretically feasible.
For example, bitwise-ing XOR an encrypted value with itself, gets us an … Continue reading Bitwise operations in FHE
We’re trying to build a packet sniffer that can search and quarantine malware in encrypted transactions without decrypting said transactions.
At present, we’re exploring whether homomorphic encryption schemes can help us look for patterns … Continue reading Is it possible to search HTTPS messages using homomorphic encryption?
Alice needs to get non public information from Bob, validate it (let’s say check that birth day is between 1900 and now) and forward it to Charlie. There’s an end to end encryption between Alice and Bob and Alice and Charlie.
If the compu… Continue reading How to safely handle non public data in memory
