Public Key Infrastructure (CYRUS)
This course explores practical cryptography, covering secure communication requirements, cryptographic primitives and their properties. Developed within the framework of the CYRUS project (funded by the DIGITAL Europe Programme of the European Union) the course 'Public Key Infrastructure' emphasises the importance of understanding how cryptographic pieces fit together to ensure data protection.
Why this course?
In today’s digital landscape, cryptography plays a vital role in protecting the confidentiality and integrity of data in all states. Modern cryptographic functions are provided by well-established libraries, such as OpenSSL. However, understanding how these components work together is essential, as improper implementation can entirely undermine their effectiveness.
This course explores practical cryptography from the ground up, combining theory, hands-on practice with OpenSSL and real-life case studies. Participants will first define secure communication requirements, such as confidentiality and integrity, before moving on to cryptographic primitives and their properties. Topics include symmetric encryption modes, hashing, message authentication codes (MACs) and their correct usage. The course then transitions to asymmetric encryption, exploring RSA, DSA and ECC, and examines how these building blocks form the Public Key Infrastructure (PKI), certificates and the root of trust. Finally, participants build the TLS protocol and investigate its vulnerabilities.
Learning outcomes
Upon successful completion of this training, participants will:
- Understand, and be able to explain, the basic concepts surrounding security, IT security and secure coding.
- Gain a practical understanding of cryptography.
- Comprehend the requirements of secure communication.
Further information
The course is perfect for anyone working directly or indirectly with cryptographic functions. By following the practices and recommendations outlined in this course, participants ensure that applied cryptography genuinely serves its purpose and protect data as intended.
The training is free of charge and offered as self-paced e-learning available on demand from April 2025 to October 2025 as well as an online instructor-led session on XXXX with a duration of approximately 4 hours.
CYRUS aims to develop a novel training programme to foster innovation in cybersecurity and support the ability of organisations working in transport and manufacturing to mitigate cyber attacks and online threats.
