Review of the Security of Backward-Compatible Automotive Inter-ECU Communication [PDF]

IEEE Access, 2021
Advanced electronic units inside modern vehicles have enhanced the driving experience, but also introduced a myriad of security problems due to the inherent limitations of the internal communication protocol. In the last two decades, a number of security

Dynamic Pattern Matching on Encrypted Data With Forward and Backward Security

IET Information Security
Pattern matching is widely used in applications such as genomic data query analysis, network intrusion detection, and deep packet inspection (DPI). Performing pattern matching on plaintext data is straightforward, but the need to protect the security of ...

Forward and Backward-Secure Range-Searchable Symmetric Encryption [PDF]

Proceedings on Privacy Enhancing Technologies, 2021
Abstract Dynamic searchable symmetric encryption (DSSE) allows a client to query or update an outsourced encrypted database. Range queries are commonly needed. Previous range-searchable schemes either do not support updates natively (SIGMOD’16) or use file indexes of many long bit-vectors for distinct keywords, which only support ...

Shedding Light on Blind Spot of Backward Privacy in Dynamic Searchable Symmetric Encryption

IEEE Access, 2023
Dynamic searchable symmetric encryption (DSSE) enables users to outsource their data while retaining the capability to search and update on the encrypted database. Although various DSSE schemes have been proposed to achieve higher efficiency and stronger

A Forward-Secure Signature with Backward-Secure Detection [PDF]

2008 International Conference on Information Security and Assurance (isa 2008), 2008
In this paper, we propose a method to enhance the security of Abdalla and Reyzin 's forward-secure signature scheme, by producing a backward-secure detection. In the proposed scheme, we embedded the hash-chain into the forward-secure signature scheme. It achieves not only forward-security but also backward-security for the digital signature.

Secure Bilevel Asynchronous Vertical Federated Learning with Backward Updating

Proceedings of the AAAI Conference on Artificial Intelligence, 2021
Vertical federated learning (VFL) attracts increasing attention due to the emerging demands of multi-party collaborative modeling and concerns of privacy leakage. In the real VFL applications, usually only one or partial parties hold labels, which makes it challenging for all parties to collaboratively learn the model without privacy leakage. Meanwhile,
