A:Answer Hello Damian! All of our Mice & Keyboards solutions have an encrypted wireless connection, yes, including the MK295 Full-size Wireless Membrane Keyboard and Mouse Bundle. Logitech's Advanced 2.4 GHz provides 128-bit AES encryption between keyboard and receiver. Now with our newer products launching and including the latest Logi Bolt Receiver, you're getting even more protection. Logi Bolt is engineered with Bluetooth security mode 1, level 4 (also known as Secure Connection Only mode), which is Federal Information Processing Standards (FIPS)* compliant. That means Logi Bolt enforces security by means of encryption. Level 4 uses Authenticated LE Secure Connections (LESC) encrypted pairing—specifically, Elliptic Curve Diffie-Hellman P-256 (ECDH) and AES-128-CCM encryption. - Mathieu from Logitech
