Abstract
An authentication method (100) for a secure data transmission is provided, the method comprising performing a first authentication protocol (101) by using a first cipher and performing a second authentication protocol (102) by using a second cipher. Possible inputs for the first authentication protocol (101) may be one shared key or several keys, and one or two random numbers.
Claims17
An authentication method for a secure data transmission, the method comprising:
- performing, in a processor, a first authentication protocol by using a first cipher, and
- performing, in the processor, a second authentication protocol by using a second cipher, wherein the second authentication protocol replaces a handshake protocol.
A method of generating session keys for an encrypted communication, the method comprising:
- generating, in a processor, a first session key by using a first cipher;
- and
- generating, in a processor, a second session key based on the first session key by using a second cipher, wherein the second session key is used in a second authentication protocol that replaces a handshake protocol.
