Abstract:
1. A station having mutual authentication between a first entity and a second entity of a device, comprising: a first hardware entity, wherein: the first hardware entity is configured to initiate mutual authentication by sending a message to the second entity, wherein the second entity is configured to verify a first public key associated with the first hardware entity, generate a first random number, encrypt at least the first random number using the first public key in a first encryption, and send the encrypted first random number to the first hardware entity; the first hardware entity is configured to verify a second public key associated with the second entity, decrypt the encrypted first random number using a first private key corresponding to the first public key in a first decryption, generate a second random number, generate a first hash based on at least the first random number, encrypt at least the second random number and the first hash using the second public key in a second encryption, and send the encrypted second random number and first hash to the second entity, wherein the second entity is configured to decrypt the encrypted second random number and first hash using a second private key corresponding to the second public key in a second decryption, verify the first hash to authenticate the first hardware entity, generate a second hash based on at least the second random number, and send the second hash to the first hardware entity; and the first hardware entity is configured to verify the second hash to authenticate the second entity; wherein the mutual authentication is limited to no more than two encryptions comprising the first and second encryptions, and is limited to no more than two decryptions comprising the first and second decryptions.
