Overview
The dawn of large-scale quantum computing poses an existential threat to traditional cybersecurity. The protocols that secure the modern internet, Transport Layer Security (TLS), Secure Shell (SSH), and Rivest, Shamir, Adleman (RSA), are fundamentally at risk.
Key areas of critical concern:
- The cryptographic clock is ticking: Public-key cryptography (like RSA) is vulnerable to Shor’s algorithm, rendering established security protocols obsolete once higher capacity, fault-tolerant quantum computers arrive.
- The “Harvest Now, Decrypt Later” threat: Adversaries are already collecting encrypted data today, knowing they can decrypt it with future quantum capabilities, endangering proprietary, long-lived, and sensitive data.
- Regulatory imperative: Evolving global standards and compliance mandates require organisations to proactively adopt quantum-safe practices to avoid non-compliance penalties.
- Weak foundation: Current key distribution systems and pseudo-random number generators lack true quantum-resistant entropy, creating exploitable weakness in your security posture.
- Shrinking window: The transition to post-quantum cryptography (PQC) is complex. The timeframe for implementation is narrow, as quantum threats are advancing faster than current deployment timelines.
Solution
TCS provides a comprehensive suite of quantum-safe security solutions and services to help your organisation achieve crypto-agility and effectively manage the transition to a quantum-resistant state.
- Strategic consulting and advisory services: This equips your organisation to effectively prepare for the challenges posed by quantum computing. We specialise in developing strategies and enabling board-level business case development to enhance existing cryptographic solutions and initiate support for quantum-safe cryptography, ensuring long-term security and resilience.
- Design and implementation services for next-generation quantum-based security technologies:
- Quantum random number generators (QRNGs) are a special case of true random number generators (TRNGs) that generate unpredictable randomness by measuring quantum processes, which are, by nature, non-deterministic.
- Quantum key distribution (QKD) uses a cryptographic protocol utilising quantum mechanics that ensures a secure communication method. Here, two parties can generate a shared random secret key, which can then be used to encrypt and decrypt messages.
- Quantum public key infrastructure (PKI) can issue quantum-safe certificates that support PQC algorithms for robust authentication.
- Crypto inventory management with risk-based prioritisation: Building a comprehensive inventory of cryptographic assets, systematically classifying systems based on their business criticality and data sensitivity. Through risk assessments, evaluating the potential impact and likelihood of vulnerabilities, enabling prioritised remediation efforts for systems that protect essential business data.
- Quantum safe crypto migration and crypto-agility services: Facilitates the transition to PQC algorithms, ensuring that organisations can adapt to evolving security needs without experiencing significant disruptions to their operations.
