A server computing system generates a universally unique identifier (UUID) associated with a first application, the UUID to be encrypted using a private key associated with the first application to generate a first digital signature. The server computing system generates a first session key associated with the first application, the first digital signature to be encrypted using the first session key to generate a first encrypted digital signature. The server computing system encrypts the first session key using a public key associated with a second application to generate a first encrypted session key, wherein the first application and the second application are deployed with the PaaS associated with the server computing system. The server computing system transmits the UUID, the first encrypted digital signature, and the first encrypted session key to the second application using hypertext transfer protocol (HTTP) to enable the second application to authenticate the first application.
