Abstract: Technologies for counter with CBC-MAC (CCM) mode encryption include a computing device that performs a CBC-MAC authentication operation on a message with an encryption key, using a 64-bit block cipher to generate a message authentication code. The computing device generates a first 64-bit authentication block including an 8-bit flag field and a length field of between 11 and 32 bits. The flag field indicates the length of the length field. Performing the CBC-MAC authentication operation includes formatting the message into one or more 64-bit authentication blocks. The computing device performs a counter mode encryption operation on the message with the encryption key using the 64-bit block cipher to generate a cipher text. Performing the counter mode encryption includes generating multiple 64-bit keystream blocks. The computing device generates an authentication tag based on the message authentication code and a first keystream block of keystream blocks. Other embodiments are described and claimed.

Abstract: In a method for enabling devices to communicate securely, a first device dynamically generates a human body nonce (HBN) and then sends that HBN to a second device via a human body communication conduit (HBCC). After sending the HBN from the first device to the second device, the first device uses the HBN to establish security for an over-the-air (OTA) communication session between the first device and the second device. For instance, the first device may derive a key, based at least in part on the HBN, and the first device may use the key to encrypt communications to be sent OTA between the first device and the second device. Other embodiments are described and claimed.

Abstract: Systems and techniques for a System-on-a-Chip (SoC) security plugin are described herein. A component message may be received at an interconnect endpoint from an SoC component. The interconnect endpoint may pass the component message to a security component via a security interlink. The security component may secure the component message, using a cryptographic engine, to create a secured message. The secured message is delivered back to the interconnect endpoint via the security interlink and transmitted across the interconnect by the interconnect endpoint.
