Data compression has been used to improve web performance and user experience. It reduces the size of files and resources, such as images, video, and text, before their transmission over the Internet. Therefore, the process reduces the amount of data transferred and enables faster load times. However, data compression has become a source of side-channel attacks that can leak personal information about users to potential adversaries. In most previously known side-channel attacks, data leaks happen because of software-visible uses of compression.

The data encrypted online today, from financial and personal identification information to military operations and intelligence data, could be decrypted quickly by an adversary with access to a cryptographically relevant quantum computer in the future. The Post-Quantum Cryptography (PQC) Coalition has been established by a community of technologists, researchers, and expert practitioners to advance the understanding and adoption of PQC and the National Institute of Standards and Technology's (NIST) PQC algorithms.
