Security gaps identified in Internet Protocol IPsec
In collaboration with colleagues from Opole University in Poland, researchers at Horst Gorts Institute for IT Security (HGI) at Ruhr-Universität Bochum (RUB) have demonstrated that the internet protocol IPsec is vulnerable to attacks. The internet key exchange protocol IKEv1, which is part of the protocol family, has vulnerabilities that enable potential attackers to interfere with the communication process and intercept specific information. Secure and encrypted communication As an enhancement of internet protocol (IP), IPsec has been developed to ensure cryptographically secure communication via publicly accessible insecure networks, such as the internet, by using encryption and authentication mechanisms. This type of communication is often used by enterprises whose employees operate from decentralised workplaces—for example, as sales reps or from a home office—and need to access company resources. The protocol can also be used to set up virtual private network (VPNs).
