“…Both the abovementioned frameworks perform in an offline manner, and hence cannot monitor the system for malicious activities while it is in its operational mode. Additionally, there have been several solutions introduced to provide security to the substation-control center communication links [11]. For instance, Lee et al [12] suggested an end-to-end encryption and key management solution for power grid infrastructures.…”

The transition from traditional power systems into smart grid infrastructures constitutes secure data acquisition to prevent widely explored false data injection attacks. In this paper, we design, implement, and deploy a trusted sensing base (TSB) that enhances the security capabilities of traditional commodity power system sensors via enabling them to encrypt analog ac signals at data acquisition points. Nowadays, data encryption occurs at phasor measurement units (PMUs) after the measurements are sampled and digitalized at the analog-to-digital devices. Through pushing the encryption to within the sensors, TSB reduces the size of trusted computing base for the whole smart grid infrastructure and hence increases its trustworthiness. We have developed a hardware working prototype of TSB in a real-world power system test-bed, including PMUs and energy management systems. Results are very promising for practical real-world deployments. TSB encrypts analog signals on the sensor side and retrieves a very accurate estimate of them on the global positioning system-synchronized control center side with minimal latency.

“…Although conducting a cyber-attack depends on an individual's motivation, the irregularity of the routine maintenance on a SAS may be prone to attacks. Attacks, such as disabling or changing the functionality of relay settings, can be made through the user interface in the SAS where it is linked to the intelligent electronic devices (IEDs) [12], [13]. This modification can be accomplished by accessing the web server of SAS through the web-based user interface.…”

In this paper, a methodology is proposed for the evaluation of the impact of cyber attacks on the power grid. This is a systematical approach to evaluate the vulnerabilities of SCADA system at three levels, i.e., system, scenario, and access points. The impact of potential intrusion is evaluated based on the power flow solution. The cause-effect on the proposed method determines the likelihood of the consequence, which can be evaluated based on a substation outage. An IEEE 30 bus system is used to build a test case for the proposed method.

“…O uso de redes de comunicação baseadas em padrões abertos faz com que os sistemas críticos em segurança (safety) atuais possuam características relacionadas à segurança da informação (security). Poucos trabalhos têm sido realizados na área de segurança da informação para redes de comunicação em sistemas de automação, sobretudo sistemas críticos em segurança (Naedele et al (2001)). Nestes sistemas, é necessário considerar os novos modos de falha e as novas ameaças introduzidas pelo domínio da segurança da informação (security), além de relacioná-las com os demais domínios de requisitos.…”
