摘要: Abstract With the advance of wireless communication techniques and popularity embedded devices, Location-Based Service (LBS) has gained a great attention in Internet-of-Things (IoT) recently. For instance, smart transportation, reporting all drivers’ location regular frequency is conducive to sense urban traffic congestion. However, it also posts serious threat privacy because exposure real-time location. To alleviate this problem, we propose Secure Efficient Location-based (SELS) scheme for transportation paper. In SELS scheme, drivers first utilize phones encrypt their location-based data then outsource them cloud center incessantly. Then they have ability call compute ciphertext LBS queries, by using secure homomorphic encryption group signature scheme. After decrypting ciphertext, obtain accurate results queries without sacrificing privacy. Furthermore, supports multi-dimension employing weighted distance algorithm. Finally, security proved cost computation analyzed, order prove efficiency
