Cover Picture: For authentication and key agreement, it is advisable to reduce the risks of key exposure and provide an additional level of control over key usage. This can be achieved by splitting the secret key across several devices, requiring their cooperation to use the key effectively. This original article has increased security and privacy for authentication and key agreement by developing new variants of the STS-KDF protocol. In addition, the paper has STS-KDF variants for the split key setting. Future work includes implementation of the protocols and extension to the case where one of the split-key devices provides attestation for the other.
