ECC Encryption Algorithm-based ERP System Secure Internet

Recent years, with the constantly improving of enterprise informatization in our country, using software to run various affairs in enterprise operation is becoming more and more common, under this background, enterprise pay more and more attention to security problems in informatization process. ERP system is a very important role in enterprise informatization, its security condition has very closely effect on daily operation and management of enterprise. This paper taking this background as breakthrough point, based on the analyzing of security requirements in ERP system, combining with present general solution——SSL VPN, suggests that putting elliptic curve cryptosystem into SSL security protocol, and gives the theoretical model about encryption communication scheme, with this theoretical model it can save hardware resources farthest and improve the security and efficiency of ERP system remote interconnection.This paper takes security requirements of ERP system as breakthrough point, analyzing the applicability and deficiency of SSL VPN technological environment, aiming at this deficiency, seeking the way out with next generation encryption algorithm——elliptic curve cryptosystem. Compared with other cryptosystems, elliptic curve cryptosystem has some advantages such as: high security, low hardware requirement and low system resources. Considering this characteristic, this paper contrives a new encryption communication scheme. In the scheme, optimize the key link to improve execution efficiency. With the case about Web security certificate communication, discuss the practicability and applicability of this scheme.
