Abstract: Device authentication is based on the ability of a human to synchronize the movements of his or her fingers. A pairing procedure for two wireless devices may thus involve a synchronization test that is based on the relative timing of actuations of input devices on each of the wireless devices. In some aspects a synchronization test involves determining whether actuations of user input devices on two different wireless devices occurred within a defined time interval. In some aspects a synchronization test involves comparing time intervals defined by multiple actuations of user input devices on two wireless devices.

Abstract: A feature is provided that facilitates securely creating and/or replacing cryptographic keys. A first key pair is created comprising first private key and first public key. A second (spare) key pair is created comprising second private key and second public key. The second key pair is associated with the first private key. The second key pair is divided into shares and distributed to at least two shareholders. When the first key pair is to be replace, the second key pair is recreated and authenticated with at least a portion of the distributed shares. A trust level is associated with the second key pair corresponding to a trust level of the first key pair. The first key pair may be invalidated upon authentication of the second key pair. Further configurations provide for the creation of additional spare key pair.

Abstract: Embodiments describe a system and/or method for multiple party digital signatures. According to a first aspect a method comprises establishing a first validity range for a first key, establishing a first validity range for at least a second key, and determining if the validity range of the first key overlaps the first validity range of the at least a second key. A certificate is signed with the first validity range of the first key and the first validity range of the at least a second key if the validity ranges overlap. According to another embodiment, signage of the certificate is refused if the first validity range of the first key does not overlap with the first validity range of the at least a second key.

Abstract translation: 实施例描述了用于多方数字签名的系统和/或方法。 根据第一方面，一种方法包括建立第一密钥的第一有效范围，为至少第二密钥建立第一有效范围，以及确定第一密钥的有效范围是否与至少一个密钥的第一有效范围重叠 第二个关键 如果有效范围重叠，则证书具有第一密钥的第一有效范围和至少第二密钥的第一有效范围。 根据另一实施例，如果第一密钥的第一有效范围不与至少第二密钥的第一有效范围重叠，则拒绝证书的标识。

Abstract: In a communication system in which two communication entities seek to have a private or confidential communication session, a trust relationship needs first be established. The trust relationship is based on the determination of a shared secret which in turn is generated from contextual information. The contextual information can be derived from the circumstances surrounding the communication session. For example, the contextual information can include topological information, time-based information, and transactional information. The shared secret may be self-generated or received from a third party. In either event, the shared secret may be used as key material for any cryptographic protocol used between the communication entities.

Abstract translation: 在两个通信实体寻求私人或机密通信会话的通信系统中，首先需要建立信任关系。 信任关系是基于共同的秘密的确定，而这个秘密又是从上下文信息中产生的。 上下文信息可以从通信会话周围的情况导出。 例如，上下文信息可以包括拓扑信息，基于时间的信息和事务信息。 共享密钥可以是自生产的或从第三方接收的。 在任一情况下，共享秘密可以用作在通信实体之间使用的任何加密协议的关键材料。
