Abstract
Briefly, a method and apparatus to authenticate messages according to a message authentication code provided with a frame over a transport layer of a communication channel.
Claims20
An apparatus comprising:
- an authenticator to authenticate a message received from a communication layer of a communication channel, which is higher than a transport layer of the communication channel, wherein the authenticator is to provide a message authentication code to a header extension of a frame, which includes at least one payload field corresponding to the message, and wherein the message authentication code is based at least on the payload field;
- and
- a transmitter to transmit the frame on the transport layer.
A method comprising:
- authenticating a message received from a communication layer of a communication channel, which is higher than a transport layer of the communication channel, wherein the authenticating includes providing a message authentication code to a header extension of a frame, which includes at least one payload field corresponding to the message, and wherein the message authentication code is based at least on the payload field;
- and
- transmitting the frame over the transport layer.
A cellular communication system comprising:
- a radio network controller having a network processor, wherein the network processor comprises:
- an authenticator to authenticate a message received from a communication layer of a communication channel, which is higher than a transport layer of the communication channel, wherein the authenticator is to provide a message authentication code to a header extension of a frame, which includes at least one payload field corresponding to the message, and wherein the message authentication code is based at least on the payload field;
- and
- a transmitter to transmit the frame on the transport layer.
