    摘要： In a system and method for authenticating a client device by an authentication device, the client device user is assigned a PIN generated by the authentication device. The user provides the PIN and a password to the client device, from which the client device generates a symmetric key and further generates a public/private key pair. The private key is encrypted using the symmetric key and stored in encrypted form only. The public key and a message authentication code generated from the PIN are provided to the authentication device, which stores the public key. Subsequently, when the user seeks to be authenticated, the user enters a password at the client device, which is used to generate a symmetric key to decrypt the encrypted private key. A message to the authentication device is signed using the resultant value. The authentication device uses the public key to verify the signature of the message.

    摘要： A system and method for securing data for redirecting and transporting over a wireless network are generally described herein. In accordance with some embodiments, when it is determined that an electronic message that is protected with a first encryption algorithm is to be transported over a wireless network to a wireless device, the electronic message is converted to a data structure that is recognizable by the wireless device and the data structure is encrypted with a second encryption algorithm using a random session key. The second encryption algorithm has a stronger security than the first encryption algorithm. The random session key is encrypted with a public key and packets that comprise the encrypted data structure and the encrypted random session key are transmitted to the wireless device over the wireless network.
