Increasing the security of the ping-pong protocol by using many mutually unbiased bases
This work addresses security vulnerabilities in quantum communication protocols, offering incremental improvements for applications in secure data transmission.
The authors tackled the problem of improving the security of the ping-pong protocol by proposing an extended version that uses many mutually unbiased bases in the control mode, showing that increasing the number of bases enhances security and providing upper bounds on eavesdropping non-detection probability.
In this paper we propose an extended version of the ping-pong protocol and study its security. The proposed protocol incorporates the usage of mutually unbiased bases in the control mode. We show that, by increasing the number of bases, it is possible to improve the security of this protocol. We also provide the upper bounds on eavesdropping average non-detection probability and propose a control mode modification that increases the attack detection probability.
