While fully device-independent security in (BB84-like) prepare-and-measure quantum key distribution (QKD) is impossible, it can be guaranteed against individual attacks in a semi-device-independent (SDI) scenario, wherein no assumptions are made on the characteristics of the hardware used except for an upper bound on the dimension of the communicated system. Studying security under such minimal assumptions is especially relevant in the context of the recent quantum hacking attacks wherein the eavesdroppers can not only construct the devices used by the communicating parties but are also able to remotely alter their behavior. In this work, we study the security of a SDIQKD protocol based on the prepare-and-measure quantum implementation of a well-known cryptographic primitive, the random access code (RAC). We consider imperfect detectors and establish the critical values of the security parameters (the observed success probability of the RAC and the detection efficiency) required for guaranteeing security against eavesdroppers with and without quantum memory. Furthermore, we suggest a minimal characterization of the preparation device in order to lower the requirements for establishing a secure key.

“…It has been proved that in real world conditions, where the channel depolarization cannot be ignored, BB84 should perform better than SARG04 [11]. Also in our previous work another attack type in the presence of several eavesdroppers via a depolarizing channel was studied [12].…”

We study the effect of many eavesdroppers cloning attacks via a depolarizing channel of the BennettBrassard cryptographic protocol on the quantum error and the mutual information between honest parties. We compute the quantum error and the mutual information for an arbitrary number of attacks. We prove that the quantum error, the secret information, and the secured/unsecured transition depend strongly on the eavesdroppers' number, their angle of attack, and the depolarizing parameter. However, when all the eavesdroppers attack with an identical angle the quantum error increases with increase in the eavesdroppers' number and/or decrease of the depolarizing parameter p for 0 ≤ p ≤ 0.165, while for p > 0.165, the lost information is greater than the mutual information exchanged between honest parties independently of the eavesdropper number and the angle of attack.

“…The intercept-resend attack is approached on the quantum communication channel (Garapo et al, 2016). Another study found that the quantum error rate decreases when increasing the depolarizing parameter characterizing the noise of the channel after applying the disturbance effect of a depolarizing channel on the security of the QKD of the four-state BB84 protocol has been applied (Dehmani et al, 2012). Another paper presents a novel analytical model to investigate the eavesdropping attacks in wireless net of things; the results indicate that the probability of eavesdropping attacks heavily depends on the shadow fading effect, the path loss effect, Rayleigh fading effect, and the antenna models (Li et al, 2016).…”

Intercept-Resend Attack on SARG04 Protocol: An Extended Work

In this paper, intercept/resend eavesdropper attack over SARG04 quantum key distribution protocol is investigated by bounding the information of an eavesdropper; then, the attack has been analyzed. In 2019, simulation and enhancement of the performance of SARG04 protocol have been done by the same research group in terms of error correction stage using multiparity rather than single parity (Omar, 2019). The probability of detecting the case in the random secret key by eavesdropper is estimated. The results of intercept/resend eavesdropper attack proved that the attack has a significant impact on the operation of the SARG04 protocol in terms of the final key length.
