Abstract

Various examples are directed to systems and methods for communications security. For example, a computing device may generate a connection between the computing device and a client device. A first application executing at the computing device may send a first application session key to the client device via the connection. The first application may perform a cryptographic operation on a first message based at least in part on the first application session key to generate a first cryptographic result and send the first cryptographic result to the client device via the connection. The first application may receive a second cryptographic result from the client device via the connection and determine that the second cryptographic result was obtained with the first application session key.

Dependent claims

A system for secure communication;

comprising:
a computing device comprising at least one processor and a memory in communication with the at least one processor, comprising:
a connection circuit to generate a connection be the computing device and a client device;
a first application executing at the computing device to:
send a first application session key to the client device via the connection;
perform a cryptographic operation on a first message based at least in part on the first application session key to generate a first cryptographic result;
send the first cryptographic result to the client device via the connection;
receive a second message from the client device via the connection, the second message comprising a second cryptographic result;
determine that the second cryptographic result was obtained with the first application session key;
determine that the client device does not possess the first application session key;
and
prompt a reset of the client device.

9 more elements

At least one non-transitory computer readable medium comprising instructions to perform:

generating a connection between a computing device and a client device;
sending, by a first application executing at a computing device, a first application session key to the client device via the connection;
performing, by the first application, a cryptographic operation on a first message based at least in part on the first application session key to generate a first cryptographic result;
sending, by the first application, the first cryptographic result to the client device via the connection;
receiving, by the first application;
a second message from the client device via the connection, the second message comprising a second cryptographic result;
determining, by the first application, that the second cryptographic result was obtained with the first application session key
