摘要： During generation of a signature on a message to create a signed message, a signer determines one of the signature components such that particular information can be extracted from the signature component. The particular information may be related to one or more of the signer and the message to be signed. After receiving a signed message purported to be signed by the signer, a verifier can extract the particular information from the signature component.

摘要： An elliptic curve random number generator avoids escrow keys by choosing a point Q on the elliptic curve as verifiably random. An arbitrary string is chosen and a hash of that string computed. The hash is then converted to a field element of the desired field, the field element regarded as the x-coordinate of a point Q on the elliptic curve and the x-coordinate is tested for validity on the desired elliptic curve. If valid, the x-coordinate is decompressed to the point Q, wherein the choice of which is the two points is also derived from the hash value. Intentional use of escrow keys can provide for back up functionality. The relationship between P and Q is used as an escrow key and stored by for a security domain. The administrator logs the output of the generator to reconstruct the random number with the escrow key.

摘要： A device and method are provided for a device that communicates security information to a user entering content into the device. In an aspect, the device may access content from a server over a connection through the network. The device displays the content on a user interface of the device. The device detects information entered into a field of the displayed content and evaluates a security state of the device. If the security state is below a security threshold and, if the entered information is identified as protected information based on stored criteria, the device displaying a visual indication on the user interface.
