摘要： Master and slave Bluetooth-enabled devices communicate with other by sending messages using a carrier frequency that is constantly hopping from one frequency to another. In the prior art, each frequency in the sequence of frequencies, known as a hopping sequence, is determined as a known function of the master's Bluetooth address (BD_ADDR) and a universal time parameter. A computer-strong eavesdropper who is listening to one or more frequency bands over a period of time and within range of a user's piconet could determine the BD_ADDR of the user's device by comparing a detected hopping sequence with the hopping sequence associated with each possible BD_ADDR. Once the BD_ADDR of a user's device is determined, the user's location can thereafter be tracked as he moves from location to location using that device. To prevent this, the hopping sequence is determined as a known function of the master's BD_ADDR, a universal time parameter and a seed, which is a random or pseudo-random number communicated between the master to the slave and which is changed each time a new session begins on one of the user's devices operating on the piconet. The eavesdropper is then impeded from associating a detected pattern of channel usage with a particular master's BD_ADDR and its user.

摘要： A repeatable cryptographic key is generated based on varying parameters which represent physical measurements. Locations within a share table, which locations store valid and invalid cryptographic shares, are identified as a function of received varying parameters. The share table is configured such that locations which are expected to be identified by legitimate access attempts contain valid cryptographic shares, and locations which are not expected to be identified by legitimate access attempts contain invalid cryptographic shares. The share table configuration may be modified based on prior history of legitimate access attempts. In various embodiments, the stored shares may be encrypted or compressed. A keystroke feature authentication embodiment uses the inventive techniques to implement an authentication system which authenticates based on an entered password and the manner in which (e.g. keystroke dynamics) the keystroke is entered. Another embodiment uses the inventive techniques to protect sensitive database information which is accessible using DNA measurements.

摘要： Rather than including a static network descriptor in messages transmitted between master and slave Bluetooth-enabled devices communicating on a piconet, which network descriptor is computed as a known function of the master's Bluetooth address (BD_ADDR), the network descriptor is changed each time a new session beings on one of the devices. This prevents an intentional eavesdropper, who may be in proximity to the piconet and who may be listening for and detecting the network descriptor included within these messages, from associating a detected network descriptor with a particular device of a user and thereafter using that network descriptor to track the location of the user who is carrying and using that device. The network descriptor, the channel access code (CAC), is changed each time a new session begins by computing it as a known function of a seed and the master's BD_ADDR, wherein the seed is a random number chosen at the beginning of each new session by the master. For further security, CAC is changed not only when a new session begins but within each session on a periodic basis. For the latter, the seed is a combination of the random number generated for each session by the master and a time parameter associated with the master.
摘要翻译：在将微网上通信的主和从蓝牙设备之间传送的消息中包含静态网络描述符，而不是将网络描述符计算为主机蓝牙地址（BD_ADDR）的已知功能，网络描述符每次都会更改其中一个设备上的会话生成。这防止了可能在微微网附近并且可能正在监听并检测包括在这些消息中的网络描述符的有意窃听者将检测到的网络描述符与用户的特定设备相关联，并且此后使用该网络描述符跟踪携带和使用该设备的用户的位置。网络描述符，信道访问代码（CAC），在每次新会话开始时都被改变，将其计算为种子的已知功能和主机的BD_ADDR，其中种子是在每个新会话开始时选择的随机数由主人。为了进一步的安全性，CAC不仅在新会话开始时，而且在每个会话期间定期更改。对于后者，种子是由主机为每个会话产生的随机数和与主机相关联的时间参数的组合。

摘要： An exponentiation operation or other computational task associated with a cryptographic protocol is performed in a secure distributed manner using multiple machines, e.g., a client device and multiple servers of a computer network. The computational task is transformed by an originator machine before being sent to one or more external servers for execution. The transformation may include replication and dependency operations to provide robustness to errors in the computations performed by the external servers, and blinding and permutation operations to provide privacy for secret information associated with the computational task. The transformed computational task is executed by the one or more external servers, and the results of the transformed computational task are transmitted back to the originator machine. The originator machine transforms the results of the transformed computational task in a manner which permits verification that the one or more results are appropriate results for a given input. Advantageously, the invention can operate with arbitrary inputs, and provides improved computational efficiency relative to conventional techniques for both small and large batches of cryptography-related computations.

摘要： Techniques are disclosed for efficient computation of consecutive values of one-way chains and other one-way graphs in cryptographic applications. The one-way chain or graph may be a chain of length s having positions i=1, 2, . . . s each having a corresponding value vi associated therewith, wherein the value vi is given by vi=h (vi+1), for a given hash function or other one-way function h. An initial distribution of helper values may be stored for the one-way chain of length s, e.g., at positions given by i=2j for 0≦j≦log2 s. A given one of the output values vi at a current position in the one-way chain may be computed utilizing a first helper value previously stored for another position in the one-way chain between the current position and an endpoint of the chain. After computation of the given output value, the positions of the helper values are adjusted so as to facilitate computation of subsequent output values. Advantageously, a storage-computation product associated with generation of the output values of the one-way chain has a complexity O((log s)2).
