The emergence of virtualization in 5G cloud computing networks puts it at greater risk of cyber-attacks, with a major reliance on the communication between virtual systems. To address these concerns, this paper proposes a secure serverless communication scheme for virtual systems in 5G cloud networks. A system with two roles, sender and receiver, is used to exchange control messages with the sender being responsible for authentication and encryption while the receiver being responsible for decryption and validation. To ensure secure and reliable communication, the proposed scheme uses the Elliptic Curve Cryptography (ECC) method, along with a proposal of a symmetric cryptographic algorithm called AES-CTR. In addition, the proposed scheme also includes a distributed identity base approach to prevent replay and man-in-the-middle attacks. Simulation results demonstrate that the proposed scheme can securely and reliably transfer data between virtual systems in 5G cloud networks and achieve higher efficiency in terms of security as compared to existing schemes. Additionally, the proposed scheme is verified in an NS-3 simulation framework
