Maintaining secrecy when information leakage is unavoidable
… short keys, and (b) hash functions that leak no information about their input, yet-paradoxically-allow testing if a candidate vector is close to the input. One of the technical contributions of this research is to provide new, cryptographic uses of mathematical tools from complexity theory known …

Exploring Information Leakage in Historical Stock Market Data
<p>Information leakage is a major concern for traders who want to execute large orders without affecting the market price. In this paper, we explore the sources and effects of information leakage in historical stock market data using various methods and metrics. We first define information leakage …

Privacy implications of information leakage from IP addresses - a web fingerprinting approach
… Alexa’s top websites to gauge the amount of information leaked by IP addresses. We build a page load fingerprint for each of the websites crawled and filter the websites that have uniquely identifying IP addresses mapped to them. We build a neural network to study how accurately the …

Prevention of personally identifiable information leakage in ecommerce using offline data minimization and online pseudonymisation.
… surrender part of their Personally Identifiable Information (PII) hence making their personal data susceptible to leakage. Despite several solutions being already in use to protect PII, data leakage persists. To enhance PII protection and user privacy, the research proposes employing Offline Data …

Corporate Governance, Firm Performance, and Information Leakage: an Empirical Analysis of the Chinese Stock Market
… of corporate governance on firm performance and information leakage in the Chinese securities market. As one of the major emerging markets in the world, the results of this thesis are valuable not only to the Chinese market, but also to other emerging markets. To achieve this purpose, data is …

Quantification of information flow in cyber physical systems
… observations can lead to unintended cyber information leakage. Information flow analysis, which aims to control the way information flows among different entities, is better suited for CPSs than the access control security mechanism. However, quantifying information leakage in CPSs can be …

Automated exploitation of fully randomized executables
… discovering, exploiting, and combining information leakage and buffer overflow vulnerabilities to generate exploits that are robust against defenses, compilation decisions, and environment differences. Marten has generated four control flow hijacking exploits and three information …

A combined approach for hiding partial information in RSA
Partial information leakage in deterministic public-key cryptosystems refers to a problem that arises when information about either the plaintext or the key is leaked in subtle ways. Quite a common case is where there are a small number of possible messages that may be sent. An attacker may be able …

Security approaches for Radio Frequency Identification systems
… or acquire access to unauthorized corporate information such as inventory levels. In addition, current RFID mechanisms expose secrets to the readers, which opens an avenue for exploits and information leakage. I examined the RFID security and privacy issues and designed a number of systems to …

Preventing data leakage in web services
… these applications can cause sensitive data leakage both on the server and client. On the server-side, applications collect and analyze sensitive user data to monetize it. Consequently, this sensitive data can leak through data breaches or can be accessed by malicious service providers. On …

Preventing Unintended Data Access: Information Flow Control in eBPF
… is a critical resource containing sensitive information, eBPF also presents a significant attack surface for malicious actors. One of the challenging-to-detect yet easiest-to-execute attacks is sensitive information leakage, as it does not require additional privileges beyond standard eBPF …
