Cryptographic Algorithms Vulnerable to Quantum Attacks and Mitigation Strategies
Vulnerable Algorithms
- RSA (Rivest-Shamir-Adleman):
- Vulnerability: Shor’s algorithm on quantum computers can factorize large integers, breaking RSA encryption.
- ECC (Elliptic Curve Cryptography):
- Vulnerability: Quantum computers can solve the discrete logarithm problem, compromising ECC.
- DSA (Digital Signature Algorithm):
- Vulnerability: Similar to RSA and ECC, DSA is vulnerable to quantum attacks via Shor’s algorithm.
- Diffie-Hellman Key Exchange:
- Vulnerability: Relies on the discrete logarithm problem, susceptible to quantum attacks.
- Symmetric Key Algorithms (e.g., AES):
- Vulnerability: Grover’s algorithm reduces the security level, effectively halving the key length.
Mitigation Strategies: Post-Quantum Cryptography
- Lattice-Based Cryptography:
- Examples: NTRUEncrypt, LWE.
- Advantage: Hard for both classical and quantum computers.
- Code-Based Cryptography:
- Examples: McEliece.
- Advantage: Based on the hardness of decoding linear codes.
- Multivariate Polynomial Cryptography:
- Examples: Rainbow, HFE.
- Advantage: Solving multivariate quadratic equations is difficult for quantum computers.
- Hash-Based Cryptography:
- Examples: XMSS, SPHINCS+.
- Advantage: Based on collision-resistant hash functions, less impacted by quantum attacks.
- Supersingular Isogeny-Based Cryptography:
- Examples: SIDH, SIKE.
- Advantage: Uses hard problems in elliptic curve isogenies.
Research and Standardization
- NIST: Conducting a project to standardize post-quantum algorithms.
- Hybrid Schemes: Combining classical and post-quantum algorithms.
- Industry Collaboration: Companies like Google and Microsoft integrating post-quantum solutions.
These measures aim to safeguard data against future quantum threats.

Identity and Access Management (IAM) is a combination of policies and technologies that allows organizations to identify users and provide the right form of access as and when required. There has been a burst in the market with new applications, and the requirement for an organization to use these applications has increased drastically.
AWS (Amazon Web Services) provides the ability to maintain detailed permissions for your AWS account and the services offered by Amazon Cloud. You can manage permissions for individual users or groups of users, and roles can help you manage permissions for resources.
