In this chapter we will look at choosing and optimizing cryptographic algorithms, particularly for resource-constrained systems, such as embedded systems. We will look at various strategies for ...

I kind of miss the old days of passwords. Spy One says, "The rock falls with a bang," and Spy Two responds with, "Snow can be brushed off your shoes." Why the Internet didn't adopt this standard is ...

Researchers have produced a collision in iOS’s built-in hash function, raising new concerns about Apple’s CSAM-scanning system — but Apple says the finding does not threaten the integrity of the ...

TapLink introduced a new technology, called Blind Hashing, that prevents offline password attacks by making databases impossible to steal. TapLink is completely invisible to the end-user, easy to ...

Phil Goldstein is a former web editor of the CDW family of tech magazines and a veteran technology journalist. He lives in Washington, D.C., with his wife and their animals: a dog named Brenna, and ...

In a briefing on Thursday afternoon, Apple confirmed previously reported plans to deploy new technology within iOS, macOS, watchOS, and iMessage that will detect potential child abuse imagery, but ...

Hashing is a one-way cryptographic function while encryption is designed to work both ways. Encryption algorithms take input and a secret key and generate a random looking output called a ciphertext.

Update: This has now been officially announced: notably your phone will only be scanning photos uploaded to iCloud, in line with policies of all major social networks and web services. (Original story ...
