That’s what makes public key cryptosystems so secure — they’re not perfect but a conventional computer would need the lifetime of the universe to crack them. This thinking changed in 1994, when the ...

Specifically, Sala warned that “all classical public-key cryptosystems should be replaced with counterparts secure against quantum attacks.” ...

Cryptography is essential for the security of online communication, cars and implanted medical devices. However, many commonly used cryptosystems will be completely broken once large quantum ...

These post-quantum cryptosystems will need to be robust against attacks by both classical algorithms and emerging new quantum algorithms. This search has inspired a broad competition organized by the ...

Multivariate Public Key Cryptosystems (MPKCs) are cryptographic schemes based on the difficulty of solving a set of multivariate system of nonlinear equations over a finite field. MPKCs are considered ...
