With the ever-increasing requirement of storage and computation resources, it is unrealistic
for local devices (with limited sources) to implement large-scale data processing. Therefore …

Wildcard Keyword Searchable Encryption (WKSE) enables users to search desired
encrypted files with wildcard queries. Previous schemes only enabled single-character …

Emails have improved our workplace efficiency and communication. However, they are often
processed unencrypted by mail servers, leaving them open to data breaches on a single …

Fully homomorphic encryption (FHE) brings a paradigm shift in cryptographic engineering
by enabling us to resolve various unsolved problems. Among them, this work solves the …

Suppose a server holds a long text string and a receiver holds a short pattern string. Secure
pattern matching allows the receiver to learn the locations in the long text where the pattern …

With the continuous development of the Internet of Things (IoT), various IoT devices create
an incomprehensible amount of data all the time. However, the IoT devices have limited …

Secure wildcard pattern matching (WPM) allows the pattern holder to obtain the matched
positions without revealing pattern and text information about both parties. However …

Approximate pattern matching (APM) measures whether the Hamming distance between
two strings is less than a threshold value. APM has been widely utilized, such as gene …

Many secure protocols exist for the problem of determining occurrences of a pattern P as a
substring of a text string T. That is, when Alice has T, and Bob has P, the protocol computes …

Biomedical data often includes personal information, and the technology is demanded that
enables the searching of such sensitive data while protecting privacy. We consider a case in …
