Abstract
A method is presented for secure communication, the method including generating a signature using a private key, a nonce, and at least one of an identifier and a key component; and transmitting the signature, the nonce, a security parameter, and the at least one of the identifier and the key component, wherein the security parameter associates a user identity with a public key, the public key being associated with the private key.
Claims18
A method, by an electronic device, for secure communication, comprising:
- generating, by a processor of the electronic device, a signature using a private key, a nonce, and at least one of an identifier and a key component;
- and
- establishing, by the processor, a secure communication session with at least one other electronic device based on generating the signature and at least session security data associated with the at least one other electronic device.
A method, by an electronic device, for secure communication, comprising:
- establishing, by a processor of the electronic device, a secure communication session with at least one other electronic device based on session security data associated with the at least one other electronic device, the session security data comprising
- a nonce, at least one of an identifier and a key component, a security parameter, and a signature that was generated using a private key, the nonce, and the at least one of the identifier and the key component.
A method, by an electronic device, for secure communication, comprising:
- generating, by a processor of the electronic device, a MAC tag using a MAC key, a nonce, and at least one of an identifier and a key component generated by the processor based on private key information associated with the electronic device and a publicly known elliptic curve point;
- and
- establishing, by the processor, a secure communication session with the at least one other electronic device based generating the MAC tag and at least session security data associated with the at least one other electronic device.
A method, by an electronic device, for secure communication, comprising:
- establishing, by a processor of the electronic device, a secure communication session with at least one other electronic device based on session security data associated with the at least one other electronic device, the session security data comprising a nonce, at least one of an identifier and a key component, and a MAC tag that was generated using the nonce, the at least one of the identifier and the key component, and a MAC key.
An apparatus for secure communication, comprising:
- a processing circuit configured to generate a signature using a private key, a nonce, and at least one of an identifier and a key component;
- and
- a transmitter configured to transmit the signature, the nonce, a security parameter, and the at least one of the identifier and the key component, wherein the security parameter associates a user identity with a public key, the public key being associated with the private key.
An apparatus for secure communication, comprising:
- a processing circuit configured to establish a secure communication session with at least one other electronic device based on session security data associated with the at least one other electronic device, the session security data comprising a nonce, at least one of an identifier and a key component, a security parameter, and a signature that was generated using a private key, the nonce, and the at least one of the identifier and the key component.
An apparatus for secure communication, comprising:
- a processing circuit configured to generate a MAC tag using a MAC key, a nonce, and at least one of an identifier and a key component generated by the processor based on private key information associated with the electronic device and a publicly known elliptic curve point, and
- establish, a secure communication session with the at least one other electronic device based generating the MAC tag and at least session security data associated with the at least one other electronic device.
An apparatus for secure communication, comprising:
- a processing circuit configured to establish a secure communication session with at least one other electronic device based on session security data associated with the at least one other electronic device, the session security data comprising a nonce, at least one of an identifier and a key component, and a MAC tag that was generated using the nonce, the at least one of the identifier and the key component, and a MAC key.
