Certificateless-based two-party authenticated key agreement proto- col for multiple PKG environment without bilinear pairing
摘要
Abstract
Because of the high computational cost, bilinear pairing isn’t equal to mobile communication environment. This paper proposes new certificateless-based two-party authenticated key agreement protocol for a multiple PKG environ-ment without bilinear pairing, which solves the key escrow issues inherited in the identity-based schemes effectively and preventing active attack by identity authentication, and the computational cost decreases effectively without bilinear pairing. After confirming the correctness, the formal analysis based on SVO shows fulfilled authentication and security. Compared with other two-party authenticated key agreement protocols for a multiple PKG environment, the newly proposed key agreement protocol has better security and efficiency.关键词
