Abstract:
Aiming at the problems that the existing protocols for secure computation of spatially parallel straight-line distance ( SPSLD)have low efficiency and can only resist passive attacks． Based on the idea of infinity of solutions in the indeterminate system of equa-tions and the random number obfuscation method，the protocols for secure computation of SPSLD under the semi-honest model and themalicious model are designed respectively，and the correctness analyses and security proofs are carried out for the protocols． Finally，the execution efficiency of the protocols is significantly improved by complexity analysis and experimental simulation． In addition，noneof the protocols use any public key encryption algorithm，and the privacy information cannot be obtained under unlimited computing re-sources，which achieves information-theoretic security，and has important theoretical significance and application value in the fields ofaviation and internet of things．
Keywords: secure multi-party computation; spatially parallel straight-line distance; information-theoretic security; malicious model
