Current encryption algorithms will most likely not be able to cope with attacks from quantum computers.

The authors in a new work have developed a quantum chipcryptography: it can resist the attack of a quantum computer. The chip is built on the RISC-V architecture and instruction set with the inclusion of ASIC and FPGA structures. Additionally, 29 special instructions are provided to reduce the specific computational load on the crystal.
The chip is based on two algorithms forpost-quantum cryptography: Kyber and SIKE, which each in its own way represents a mechanism for encapsulating encryption keys with resistance to attacks using quantum computers.
It is emphasized that the new chip speeds up data processing ten times using the Kyber algorithm and consumes eight times less energy during operation.
Encryption using SIKE algorithms should be more protective against "quantum" attacks: this algorithm serves the new chip with a 21-fold acceleration.
