Accordingly, the external candidate selected for this post will continue to be considered an external candidate for the purposes of any future applications to the Agency.\nLocation\nESEC, Redu, Belgium\nDescription\nCryptography Evaluator Engineer in the System Security Section (TEC-SES), End-to-End Systems Division, Systems Department, Directorate of Technology, Engineering and Quality.\nThe System Security Section is responsible for the end-to-end system security engineering of the Agency’s missions, projects and activities in space, ground and user segments and communication links, as well as at system, subsystem, element and equipment level. It covers missions from study phase to definition of requirements, design, development, security integration / verification, and security service preparation, across the full stack, from physical to application layer.\nTo serve these functions, the System Security Section defines and executes the associated technology R&D and studies, as well as the required security engineering standards.\nUsing security laboratory facilities, the System Security Section performs vulnerability assessments at all levels of its responsibility, proposing detection methods, mitigation and protection measures, using security assessment tools and equipment.\nThis position will support a third party activity for the development of a national capability on the evaluation and certification of cryptographic algorithms and protocols.\nDuties\nYour tasks and responsibilities will include:\nsupporting the project manager by providing recommendations and guidance on the evaluation and certification of cryptographic algorithms;\nregular reporting to the Project Manager on the status of the duties assigned under the Project;\ndirect engagement with and advice to national customers and ESA experts on the strengths, weaknesses and design of cryptographic algorithms and parameter selection for them;\nderiving recommendations on cryptographic algorithms in relation to use case and security strength;\nfostering new security application areas for multidisciplinary activities, placing emphasis on innovative concepts, cutting-edge technologies and system architectures in the field of crypto algorithm evaluation and certification;\nsupporting the training of colleagues, as required;\ncontinuously following technological trends and evolutions in the scientific fields relevant for this position, and in particular on the latest emerging threats, exploits, and industry trends;\nbeing engaged in other technical activities outside the main project in the area of your expertise, as requested. \nTechnical competencies\nCryptographic Design and Protocol Engineering\nMathematical Foundations of Cryptography\nCryptanalysis and Cryptographic Security Assessment\nFormal Security Analysis and Proof Evaluation\nCryptographic Parameter Selection and Implementation Security\nCryptographic Evaluation, Certification and Standards\nBehavioural competencies\nResult Orientation\nOperational Efficiency\nFostering Cooperation\nRelationship Management\nContinuous Improvement\nForward Thinking\nFor more information, please refer to the ESA Core Behavioural Competencies guidebook\nEducation and professional experience\nA PhD in a relevant domain is required for this post together with 3 years of relevant professional experience.\nAdditional requirements\nExperience in:\nthe design of cryptographic algorithms and protocols;\nanalysis of real-world security strength of public and private key crypto algorithms;\nthe justified selection of parameter sets for real world crypto algorithms;\nthe certification of crypto algorithms;\ndealing with crypto evaluation facilities and good knowledge of formal crypto evaluation test standards and analysis of formal evaluation results.\nVery good knowledge of:\nmathematical foundations of modern public and private key crypto algorithms;\nnumber theory, abstract algebra, probability, discrete mathematics and computational complexity;\nsecurity definitions, assumptions, and formal security proofs and how to assess them;\nhow to to identify weaknesses in algorithm design and cryptographic constructions;\ndifferential and linear cryptanalysis, algebraic attacks, statistical attacks, and relevant attacks on public-key systems;\nhow to evaluate brute-force resistance, key sizes, security margins, and attack complexity;\nhow to assess randomness generation, key management, nonce handling, padding, and constant-time implementation requirements;\nhow implementation flaws can undermine a mathematically sound algorithm;\nhow to proof assumptions, reductions, and limitations.\nFamiliarity with formal verification or symbolic protocol analysis, where relevant.\nDiversity, Equity and Inclusiveness\nESA is an equal opportunity employer, committed to achieving diversity within the workforce and creating an inclusive working environment. We therefore welcome applications from all qualified candidates irrespective of gender, sexual orientation, ethnicity, religious beliefs, age, disability or other characteristics.\nAt the Agency we value diversity, and we welcome people with disabilities.
