Encryption and Quantum Computing: Current Events and Challenges

One of the most intriguing aspects of quantum computing is its potential impact on the encryption systems used to protect our sensitive data. Currently used cryptographic algorithms, such as RSA and ECC, are based on the difficulty of solving certain complex mathematical problems. However, quantum algorithms, such as Shor’s algorithm, can take advantage of the capabilities of quantum computing to factorize large integers much more quickly, which could compromise the security of these encryption systems.

This raises the need to develop new encryption methods resistant to quantum attacks, known as post quantum cryptography. Algorithms resistant to quantum computing, such as those based on lattices, codes, hash functions and algebraic structures, are being researched and designed. Post quantum cryptography seeks to ensure that, even with the computing power of a quantum machine, our data remains safe and secure.
