POLIIICE long term vision is to advance European LEAs to a novel lawful-interception (LI), investigation and intelligence era in which they will be able to effectively prevent, detect and investigate crime and terrorism amid the new age of communication (5G&Beyond, application level E2EE and Quantum based cryptography). These new age of communication technologies turn legacy LI solutions to totally in-effective and therefore put significant risk on Europe’s fight against crime and terrorism. POLIIICE will offer, research, validate and demonstrate array of innovative LI measures at cloud & network level as well as at edge-device level that together will enable LEAs to efficiently overcome the new age challenges and enable high throughput of LI. In addition, POLIIICE will research and model QUDDaaS (Quantum unlock, detection and decryption as a service) as an envisaged central service, potentially outsourced at pan-European level, which will harness quantum computing (enhanced by AI) for decryption of lawfully intercepted encrypted communication (which is vulnerable to Quantum’s Shor algorithm), for brute force detection of target-user’s credentials/tokens needed to access encrypted cloud-native apps and for Quantum unlock of lawfully seized mobile devices. QUDDaaS may also detect and classify lawfully intercepted communications that are resistant to Quantum decryption power and therefore can’t be decrypted. Moreover, POLIIICE also aims to improve the information exchange and cooperation among European LEAs by proposing and implementing a mechanism and procedure (‘POLEX’) for exchanging pseudo-anonymized suspect identifiers (captured by LI) between different LEAs for the purpose of detection of inter-LEA overlap in suspect identifiers which will enrich LEA intelligence and expedite investigation of cases. Both QUDDaaS and POLEX will be managed and provided at EU level through a central hub called ‘POLIIICE EU-Hub’. Notably, POLIIICE will be designed for ensuring the cost-effectiveness, security and integrity of the new age of LI and will provide the legal and ethical guidelines and framework for each of its measures while strictly complying with privacy preserving and ethics rules of operation. At exploitation level, POLIIICE project will contribute to the LI compliance standardization (defined by 3GPP/ETSI) and will recommend EU policy and regulation changes which are essential for effective adaptation of POLIIICE vision and innovative LI measures.
