Abstract: A system/method for secure communication between client devices includes receiving a request, at a secure communication platform, from a from a first client device to communicate with a second client device; determining, by the secure communication platform, whether the first client device is permitted to communicate with the second client device; if communication is permitted: generating, by the secure communication platform, a one-time use ephemeral key; transmitting, by the secure communication platform, the generated one-time use ephemeral key to the first and second client devices; establishing, by the secure communication platform, a secure communication session directly between the first and second client devices, wherein communications between the first and second client devices are encrypted and decrypted using the one-time use ephemeral key; and destroying, by the secure communication platform, the one-time use ephemeral key upon termination of the secure communication session between the first and
