Oooops!

I DID IT AGAIN!

In pruning my inactive Mastodon following/followers -- I hit the wrong button again!

That "remove all users from this domain" is much too dangerous to have available for the mindless clicking!

"Remove selected users" is what you want!

PLEASE RE-FOLLOW if you were FOLLOWING!

(I try to maintain a 1:1 Follow/Follower ratio and as you can see in the screenshot below... it isn't that way any longer!)

"opesec" opsec for people that aren't targeted by nation/state actors. common mistakes. #ope.

"sorry not sorry" i call people on the behalf of others to apologize for something

i have more #ideas but those are the three that i was just thinking about. i don't write or share much about my career weirdly enough? imposter syndrome maybe. #infosec

I don't hear "whoop," but I do hear "ope!"

Apparently, honeybees say, "Ope!" when they bump into each other:

I recently read a very interesting paper on Leakage-Abuse Attacks against Order-Preserving Encryption (OPE) schemes and Order-Revealing Encryption (ORE) Schemes.

In this paper, the researchers show how the widely used encryption schemes are inadequate. Here are some snippets from the paper.

Order-preserving encryption (#OPE) - ensures that Ek(m1)<Ek(m2) for m1<m2 and Ek the encryption algorithm. Most widely used scheme is #BCLO.

Order-revealing encryption (#ORE) - reveals ordering relations by way of a public comparison function that operates on pairs of plaintexts. Most widely used scheme is #CLWW.

Popular belief is that OPE and ORE schemes remain secure in practice for plaintext data drawn from larger domains, and practitioners could simply avoid using OPE for small-domain data.

The researchers used a non-crossing attack (min-weight non-crossing #bipartite matching) which runs in only a few hours, even for the largest target dataset, against real-world datasets using the BCLO scheme to encrypt a set of first names.

Using this attack they were able to recover almost half the data set. The leakage was even worse for last names, with almost 97% of last names trivially recoverable.

#Composition of the two (BCLO & CLWW) schemes does #decrease attack accuracy but is still far from providing acceptable security.

Exploiting known plaintexts is even easier.

Attacking frequency-hiding schemes - #Kerschbaum recently introduced a scheme that hides frequency information. However, a “#binomial” attack performs reasonably well, recovering on average 30% of first names and 7% of last names. Notably, it recovers majority of high-frequency plaintexts (despite not having frequency information leaked), suggesting these plaintexts are particularly poorly protected by any order-revealing scheme.

In terms of countermeasures, an obvious suggestion is to move towards less leaky schemes, such as those that only reveal order, including Kerschbaum's scheme and the more recent #Boneh et al. scheme based on #multilinear maps. Unfortunately in most settings there exists inherent #challenges to deployment of these schemes. Kerschbaum's scheme is relatively efficient, but requires client-side state which impedes scaling. The Boneh et al. scheme has ciphertexts larger by 10 orders of magnitude than BCLO ciphertexts and requires tens of minutes to compute encryptions.

An #introduction: I am an entire, full-time "classical" #nerd. Computers, mathematics, science, fan of "Stars, both Wars and Trek" and of non-fiction stars, too. Programming since 1983, started with Texas Instruments TI-99/4A and Timex Sinclair 1000. When working I mostly use open source languages, frameworks, and tools. Have lived in Iowa, Virginia, Massachusetts, and Michigan. Midwesterner at heart (#ope) and proud lifelong progressive Democrat. Currently in cold, snowy, quiet Grand Rapids.

And with the reinstatement, I delete all my tweets.

Ope.
