Gaio Rito, Cátia Sofia, Beatriz Piedade, Maria, Eugénio Lucas, Eugénio.  2019.  E-Government - Qualified Digital Signature Case Study. 2019 14th Iberian Conference on Information Systems and Technologies (CISTI). :1—6.

This paper presents a case study on the use and implementation of the Qualified Digital Signature. Problematics such as the degree of use, security and authenticity of Qualified Digital Signature and the publication and dissemination of documents signed in digital format are analyzed. In order to support the case study, a methodology was adopted that included interviews with municipalities that are part of the Intermunicipal Community of the region of Leiria and a computer application was developed that allowed to analyze the documents available in the institutional websites of the municipalities, the ones that were digitally signed. The results show that institutional websites are already providing documentation with Qualified Digital Signature and that the level of trust and authenticity regarding their use is considered to be mostly very positive.

Iftikhar, Jawad, Hussain, Sajid, Mansoor, Khwaja, Ali, Zeeshan, Chaudhry, Shehzad Ashraf.  2019.  Symmetric-Key Multi-Factor Biometric Authentication Scheme. 2019 2nd International Conference on Communication, Computing and Digital systems (C-CODE). :288–292.
Authentication is achieved by using different techniques, like using smart-card, identity password and biometric techniques. Some of the proposed schemes use a single factor for authentication while others combine multiple ways to provide multi-factor authentication for better security. lately, a new scheme for multi-factor authentication was presented by Cao and Ge and claimed that their scheme is highly secure and can withstand against all known attacks. In this paper, it is revealed that their scheme is still vulnerable and have some loopholes in term of reflection attack. Therefore, an improved scheme is proposed to overcome the security weaknesses of Cao and Ge's scheme. The proposed scheme resists security attacks and secure. Formal testing is carried out under a broadly-accepted simulated tool ProVerif which demonstrates that the proposed scheme is well secure.
