Abstract
The crowdsourcing-based parking reservation system is a new computing paradigm, where private owners can rent their parking spots out. Security is the main concern for parking reservation systems. However, current schemes cannot provide user privacy protection for drivers and have no key agreement functions, resulting in a lot of security problems. Moreover, current schemes are typically based on the time-consuming bilinear pairing and not suitable for real-time applications. To solve these security and efficiency problems, we present a novel security protocol with user privacy called SCPR. Similar to protocols of this field, SCPR can authenticate drivers involved in the parking reservation system. However, different from other well-known approaches, SCPR uses pseudonyms instead of real identities for providing user privacy protection for drivers and designs a novel pseudonym-based key agreement protocol. Finally, to reduce the time cost, SCPR designs several novel cryptographic algorithms based on the algebraic signature technique. By doing so, SCPR can satisfy a number of security requirements and enjoy high efficiency. Experimental results show SCPR is feasible for real world applications.

Summary
As the amount of cars increases explosively, parking is becoming a precious resource in crowded urban areas such as New York and San Francisco [1]. To provide user privacy protection, it is urgent to develop a pseudonym-based security protocol for crowdsourcing-based parking reservation systems. To reduce time cost, it is desirable to use highly efficient cryptographic operations for designing security protocols for parking reservation systems. To reduce time cost, it is important to develop a security protocol for crowdsourcing-based parking reservation systems without bilinear pairing. Taking both user privacy and time cost into account, we shall design a pseudonym-based security protocol for crowdsourcing-based parking reservation systems without bilinear pairing This security protocol should satisfy the following requirements. The other requirements (i.e., user privacy, integrity of rental information, key agreement, and time cost) have been largely neglected. Observing that the key agreement requirement is not fulfilled by current security protocols, we design a novel pseudonymbased key agreement protocol that can generate a shared key for protecting subsequent reservation transactions.
