This paper proposes a novel modulated symbols-based one-time pad(SOTP) secure transmission scheme using physical layer *** classical physical layer key generation and exclusive OR(XOR)encryption in the discrete binary space,we design a framework for modulated symbols-based one-time pad(OTP) encryption,where the cryptographic primitive and mathematical model of SOTP is given to build a practical cryptographic *** with existing physical layer encryption(PLE) schemes,we provide rigorous proof that the framework can meet perfect secrecy and correctness *** addition,we provide a specific scheme of physical layer OTP secure transmission for quadrature amplitude modulation(QAM) and phase-shift keying(PSK) symbols based on physical layer *** scheme realizes the unification of bit encryption and symbol encryption,which can adaptively select the quantization level according to the signal-to-noise ratio(SNR) to minimize the symbol error rate(SER).Further,we analyze the performance quantitatively and derive the closed-form expressions of SER,which indicates that the proposed scheme has a lower ***,simulation results verify that the proposed symbol-wise OTP secure transmission scheme can achieve perfect secrecy and high reliability.

In this paper,we propose a conjecture that endogenous security without any prior knowledge is similar to perfect secrecy without any prior *** prove the conjecture,we first establish a cryptography model of instinct function security to transform the security problem in the network domain into an encryption problem in the cryptographic ***,we inherit and apply the established ideas and means of perfect secrecy,and propose the concept,definition and corollaries of the perfect instinct function security(PIFS)corresponding to perfect ***,we take the DHR system as a concrete implementation of PIFS and propose the DHR perfect Security Theorem corresponding to Shannon’s perfect secrecy ***,we prove that the DHR satisfying the“OneTime Reconstruction”constraint is the sufficient and necessary condition to achieve perfect *** means that the existence of PIFS is also *** analysis shows that any reconfigurable system can be encrypted by its construct and that the PIFS converts the oneway transparent superiority of the attacker into a double-blind problem for both the attacker and the defender,which leads to that the attacker is impossible to obtain useful construction information from the attacks and unable to find a better way than blind trial-and-error or brute-force *** the attackers are required to have the new powerful ability to crack the structure cryptogram,the threshold of cyber security is raised to at least the same level as cryptogram deciphering,thereafter the ubiquitous cyber threats are destined to be significantly reduced.
