• The actual resolution of the detection system, theoretically estimated at 3.0 μm, has been effectively improved to 2.5 μm.
• This method significantly enhances the detection contrast, while also ensuring the effective identification of ...

The advancement of Industrial Internet-of-Things (IIoT) magnifies the cyber risk of automated production lines, especially to deception attacks that tamper with the monitoring data to prevent the manipulated operation of production lines from being ...

The increasing interest in autonomous ships within the maritime industry is driven by the pursuit of revenue optimization, operational efficiency, safety improvement and going greener. However, the industry’s increasing reliance on emerging ...

Non-Fungible Tokens (NFTs) have created new and interesting ways to own digital assets. Our work defines non-fungible tokens as a pair and addresses challenges in cross-chain NFT transfers, particularly on interoperability between siloed ...

Critical infrastructure becomes a strategic target in the midst of a cyberwar. A classic example is the Stuxnet attack targeting Iran’s nuclear power plant in 20101 by exploiting four zero-day flaws to compromise supervisory control and data acquisition (...

With the widespread adoption of cloud computing, it is a popular trend to migrate shortest path and distance (SPD) retrieval on large-scale graphs to cloud environments, harnessing their immense computational capabilities. To protect sensitive ...

It is our great pleasure to welcome you to ACM AsiaCCS 2024, the 19th ACM Asia Conference on Computer and Communications Security. AsiaCCS 2024 takes place in Singapore from 1 July to 5 July.

Federated learning (FL) is becoming a major driving force behind machine learning as a service, where customers (clients) collaboratively benefit from shared local updates under the orchestration of the service provider (server). Representing clients' ...

The emergence of autonomous ships represents a significant advancement in maritime technology, promising enhanced efficiency, reduced operating costs and reducing or even completely removing crews from hazardous environments. However, the progress ...

The improvement of quantum computing poses a significant threat to cryptographic security. It enables the potential utilization of quantum algorithms to compromise classical cryptographic algorithms, such as public-key cryptosystems including RSA (...

Data integrity attacks on the various meter readings found in smart grid systems can be executed to be undetectable by current detection algorithms used in smart grid systems. These unobservable cyberattacks present a potentially dangerous threat ...

Cybersecurity is a growing concern for maritime sector. Modern ships are practical realism of cyber physical systems that utilize both information technologies and operational technologies. Cybersecurity incidents on such systems require robust ...

Group time-based one-time passwords (GTOTP) is a novel lightweight cryptographic primitive for achieving anonymous client authentication, which enables the efficient generation of time-based one-time passwords on behalf of a group without revealing any ...

Vehicular cloud computing (VCC) is a network architecture that allows a group of entities (i.e., vehicles/roadside infrastructures) to share their resources with other entities. Task delivery in VCC involves the delegation of computation/storage task from ...

Blockchain rewriting with fine-grained access control allows a user to create a transaction associated with a set of attributes, while a modifier who possesses sufficient rewriting privileges from a trusted authority satisfying the attribute set can ...

Programmable logic controllers (PLCs), the essential components of critical infrastructure, play a crucial role in various industrial manufacturing processes. Recent attack events show that attackers have a strong interest in tampering with the ...

At ACSAC 2019, we introduced a new cryptographic primitive called proof of aliveness (PoA), allowing us to remotely and automatically track the running status (aliveness) of devices in the fields in cyber-physical systems. We proposed to use a one-way ...

Recently, autonomous and connected vehicles have gained popularity, revolutionizing consumer mobility. On the other hand, they are also becoming new targets exposing new attack vectors and vulnerabilities that may lead to critical consequences. In ...

Networked Programmable Logic Controllers (PLCs) are proprietary industrial devices utilized in critical infrastructure that execute control logic applications in complex proprietary runtime environments that provide standardized access to the hardware ...
