Locally Decodable/Correctable Codes for Insertions and Deletions
Alexander R. Block, Jeremiah Blocki, Elena Grigorescu +2
Recent efforts in coding theory have focused on building codes for insertions and deletions, called insdel codes, with optimal trade-offs between their redundancy and their error-c…
Password Strength Signaling: A Counter-Intuitive Defense Against Password Cracking
Wenjie Bai, Jeremiah Blocki, Ben Harsha
We introduce password strength information signaling as a novel, yet counter-intuitive, defense mechanism against password cracking attacks. Recent breaches have exposed billions o…
HACCLE: Metaprogramming for Secure Multi-Party Computation -- Extended Version
Yuyan Bao, Kirshanthan Sundararajah, Raghav Malik +17
Cryptographic techniques have the potential to enable distrusting parties to collaborate in fundamentally new ways, but their practical implementation poses numerous challenges. An…
On the Economics of Offline Password Cracking
Jeremiah Blocki, Ben Harsha, Samson Zhou
We develop an economic model of an offline password cracker which allows us to make quantitative predictions about the fraction of accounts that a rational password attacker would…
On the Security of Proofs of Sequential Work in a Post-Quantum World
Jeremiah Blocki, Seunghoon Lee, Samson Zhou
A Proof of Sequential Work (PoSW) allows a prover to convince a resource-bounded verifier that the prover invested a substantial amount of sequential time to perform some underlyin…
DALock: Distribution Aware Password Throttling
Jeremiah Blocki, Wuwei Zhang
Large-scale online password guessing attacks are wide-spread and continuously qualified as one of the top cyber-security risks. The common method for mitigating the risk of online…
