    • A challenge response scheme authenticates a requesting device by an authenticating device. The authenticating device generates and issues a challenge to the requesting device. The requesting device combines the challenge with a hash of a password provided by a user, and the combination is further hashed in order to generate a requesting encryption key used to encrypt the user supplied password. The encrypted user supplied password is sent to the authenticating device as a response to the issued challenge. The authenticating device generates an authenticating encryption key by generating the hash of a combination of the challenge and a stored hash of an authenticating device password. The authenticating encryption key is used to decrypt the response in order to retrieve the user-supplied password. If the user-supplied password hash matches the stored authenticating device password hash, the requesting device is authenticated and the authenticating device is in possession of the password.
    • 挑战响应方案通过认证设备认证请求设备。 认证设备生成并向请求设备发出质询。 请求设备将挑战与由用户提供的密码的散列相结合,并且组合进一步进行散列,以便生成用于加密用户提供的密码的请求加密密钥。 加密的用户提供的密码作为对发布的挑战的响应被发送到认证设备。 认证设备通过生成质询的组合和存储的认证设备密码的哈希的散列来生成认证加密密钥。 认证加密密钥用于解密响应,以便检索用户提供的密码。 如果用户提供的密码哈希与存储的认证设备密码散列匹配,则请求设备被认证,认证设备拥有密码。

    • Electronic messages are sent from a sending system to an identified recipient and are encrypted using information contained in a certificate for that recipient. An electronic device and method are provided for detecting receipt of a command to initiate transmission of a composed message to a recipient, and after said detection but prior to transmitting the message, determining that no valid digital certificate for said recipient is available at the communication device; retrieving a valid digital certificate for said recipient from a source over a network; and encrypting said composed message using the valid digital certificate; then initiating transmission of the encrypted, composed message to the recipient. Retrieval of the valid digital certificate can include repeated retrieval and validation of certificates until a valid certificate is obtained.
