Abstract: Methods, apparatuses and systems for peer-to-peer secure communication are disclosed. In an example, a mobile security apparatus (“MSA”) is connected to a first endpoint device and includes a memory device storing a list of MSAs that are designated as being within a circle of trust (“CoT”) of the MSA. The list includes an Internet Protocol (“IP”) address, a public key, and an identifier of at least one endpoint device for each of the MSAs. The apparatus also includes a processor configured to receive a selection of content from the first endpoint device for transmission to the second endpoint device. After determining the second endpoint device corresponds to a second MSA that is included within the CoT, the processor encrypts a message including the content using the public key associated with the second MSA and transmits the encrypted message using the IP address of the second MSA.
