Abstract: There are disclosed systems and methods for creating a self-signed implicit certificate. In one embodiment, the self-signed implicit certificate is generated and operated upon using transformations of a nature similar to the transformations used in the ECQV protocol. In such a system, a root CA or other computing device avoids having to generate an explicit self-signed certificate by instead generating a self-signed implicit certificate.
Abstract translation: 公开了用于创建自签名隐式证书的系统和方法。 在一个实施例中，使用与ECQV协议中使用的转换类似的性质的变换来生成和操作自签名隐式证书。 在这样的系统中，根CA或其他计算设备避免必须通过代替生成自签名隐式证书来生成显式的自签名证书。

Abstract: The invention relates to a method of generating an implicit certificate and a method of generating a private key from a public key. The method involves a method generating an implicit certificate in three phases. The public key may be an entity's identity or derived from an entity's identify. Only the owner of the public key possesses complete information to generate the corresponding private key. No authority is required to nor able to generate an entity's private key.

Abstract: 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.

Abstract: A shielding article is provided, for shielding a device enabled for proximity-based communications, for example, NFC-enabled devices. The shielding article comprises a shielding component configured to prevent operation of an antenna of the device used for conducting proximity-based communications, without preventing operation of at least one other antenna of the device when the shielding component is aligned with the antenna used for conducting proximity-based communications. The shielding article may be separate from, or included in an accessory or carrying article and may be fixed or detachably coupled thereto.

Abstract: A method is presented to compute square roots of finite field elements from the prime finite field of characteristic p over which points lie on a defined elliptic curve. Specifically, while performing point decompression of points that lie on a standardized elliptic curve over a prime finite field of characteristic 2224−296+1, the present method utilizes short Lucas sub-sequences to optimize the implementation of a modified version of Mueller's square root algorithm, to find the square root modulo of a prime number. The resulting method is at least twice as fast as standard methods employed for square root computations performed on elliptic curves.
Abstract translation: 提出了一种从特征p的主有限域计算有限域元素的平方根的方法，其中点位于定义的椭圆曲线上。 具体来说，当在特征2224-296 + 1的主要有限域上执行位于标准化椭圆曲线上的点的点解压缩时，本方法利用短Lucas子序列来优化Mueller平方根算法的修改版本的实现 ，找到素数的平方根模。 所得到的方法至少是用于在椭圆曲线上进行的平方根计算的标准方法的两倍。

Abstract: A key establishment protocol includes the generation of a value of cryptographic function, typically a hash, of a session key and public information. This value is transferred between correspondents together with the information necessary to generate the session key. Provided the session key has not been compromised, the value of the cryptographic function will be the same at each of the correspondents. The value of the cryptographic function cannot be compromised or modified without access to the session key.
