摘要： A Secure Virtual Point of Service (SVPOS) that coordinates the authentication, authorization, and identity, settlement, arbitration and non-repudiation for an electronic commercial transaction. For each commercial transaction, both the buyer and merchant authenticate itself to the SVPOS and create two unique transaction encryption keys, one for the buyer and one for the merchant. The merchant uses both encryption keys to encrypt a package that include at least product identification. The merchant and buyer calculate a hash of the package and transmit the calculated hash to the SVPOS for comparison to prevent repudiation. If the calculated hash is identical the buyer receives the merchants encryption key and decrypts the package. Payment is released by the SVPOS if the buyer is satisfied with the package via a Parlay system. If the buyer is not satisfied, said SVPOS performs arbitration between the buyer and merchant to determine if the package is correct.

摘要： An inventive scheme for detecting parties responsible for repeated malicious activities in secure and anonymous communication is presented. The scheme comprises generating a pool of keys, distributing to and associating with each party a small number of keys chosen randomly from the pool, revoking a key when it is detected as used in a malicious activity, creating a set of parties associated with the revoked key, revoking additional keys randomly chosen among the keys not currently revoked, selecting new keys, and when a party requests an updated key, sending the updated key selected from among the new keys to the requesting party, wherein if an other malicious activity is detected, creating another set of the parties associated with the other malicious activity and identifying the parties in both sets. The steps of the inventive scheme are repeated until only one party is in the intersection set.

摘要： The present invention advantageously provides a system and method for management of cryptographic keys and certificates for a plurality of vehicles. Each vehicle of the plurality of vehicles generates public/private key pairs, requests multiple time-distributed certificates, creates an encrypted identity, and surrenders expired certificates. An assigning authority receives the public/private key pairs, the request for multiple time-distributed certificates, the encrypted identity, and the expired certificates from said vehicle. The assigning authority authorizes the vehicle with an authorizing authority, validates the expired certificates, proves ownership, and distributes the requested time-distributed certificates to said vehicle. Validation can comprise checking expired certificates against misused, compromised and/or previously surrendered certificates. Time-distributed certificates can have lifetimes adjustable based on certificate misuse detection system algorithms, amount of malicious activity detected, and/or certificate authority capacity.

摘要： A method and system are provided for timed-release cryptography. A sender encrypts data in a timed-release fashion such that a receiver based on information exchanged with a server decrypts the encrypted data at or after a release time without revealing to the server any information about the sender, the data, and the release time. In one embodiment, the sender encrypts a key and a release time based on a public key of the receiver and encrypts the data based on the encrypted key. The server determines a condition, which is a function of the encrypted key, the encrypted release time, and a current time. The server then sends the condition to the receiver using a conditional oblivious transfer method. If the current time as determined by the server is greater than or equal to the release time, the receiver determines the encrypted key based on the condition. The receiver then uses the encrypted key to decrypt the encrypted data. However, if the current time is less than the release time, the receiver fails to determine the encrypted key based on the condition, and thus, fails to decrypt the encrypted data.
摘要翻译： 提供了一种定时释放加密技术的方法和系统。 发送方以定时发布的方式加密数据，使得基于与服务器交换的信息的接收者在释放时间之内或之后解密加密数据，而不向服务器透露关于发送者，数据和释放时间的任何信息。 在一个实施例中，发送者基于接收者的公钥加密密钥和释放时间，并且基于加密的密钥对数据进行加密。 服务器确定一个条件，它是加密密钥的函数，加密的释放时间和当前时间。 然后，服务器使用条件忽略传输方法将条件发送给接收方。 如果由服务器确定的当前时间大于或等于发布时间，接收者将根据条件确定加密的密钥。 然后，接收器使用加密的密钥来解密加密的数据。 然而，如果当前时间小于释放时间，则接收机根据条件无法确定加密密钥，因此无法解密加密数据。
