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.
Claims12
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, at least the signature being destined for reception by at least one other electronic device;
- 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 and obtained by the electronic device, wherein the session security data is generated, at least in part, by 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 and obtained by the electronic device, wherein the session security data is generated, at least in part, by 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 by the at least one other electronic device 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 signature using a private key, a nonce, and at least one of an identifier and a key component;
- and
- a transmitter configured to transmit session security data comprising the signature, the nonce, a security parameter, and the at least one of the identifier and the key component, where the session security data is destined for reception by at least one electronic device for establishing a secure communication session therewith, and 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 and obtained by the 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 by the at least one other electronic device using a private key, the nonce, and the at least one of the identifier and the key component.
