Abstract

Due to the increased application of information and communication technologies in the public sector, the amount of data being produced and processed by the public sector has been constantly growing during the past years. As these data can also be useful for the general public and the corporate sector, current initiatives attempt to make these data publicly available. Recent work on this topic has shown that publishing of public sector data potentially raises several issues regarding data integrity and authenticity. These issues render the
implementation of solutions based on trusted and reliable public sector data difficult. However, recent work has proposed electronic signatures in general and redactable electronic signatures in particular as adequate means to address these issues. While a variety of redactable signature schemes has been introduced in literature, their
capabilities to assure the integrity and authenticity of published public sector data has not been assessed so far.
This renders a concrete implementation of solutions based on redactable signatures impossible.
To overcome this problem, this paper first identifies and discusses legal, organisational, and technical requirements that need to be met by redactable signature schemes when applied to public sector data to be published. Afterwards, different existing redactable signature schemes are examined and discussed in more detail. Based on the previously identified requirements, the different redactable signature schemes are then assessed in detail. The conducted assessment reveals that sanitizable signature schemes, which represent a subset of redactable signature schemes, are especially suited to meet the predefined requirements. Among the wide set of existing sanitizable signature schemes, the conducted survey has revealed two concrete schemes to be best suited to assure the integrity and authenticity of public sector data to be published. The results obtained from the conducted survey will serve as input and basis for the implementation of solutions based on trusted and
reliable public sector data
