    摘要: Scalable session management is achieved by generating a cookie that includes an encrypted session key and encrypted cookie data. The cookie data is encrypted using the session key. The session key is then signed and encrypted using one or more public/private key pairs. The encrypted session key can be decrypted and verified using the same private/public key pair(s). Once verified, the decrypted session key can then be used to decrypt and verify the encrypted cookie data. A first server having the private/public key pair(s) may generate the cookie using a randomly generated session key. A second server having the same private/public key pair(s) may decrypt and verify the cookie even if the session key is not initially installed on the second server. A session key cache may be used to provide session key lookup to save public/private key operations on the servers.

    摘要: A system and method for securely roaming private data from a first client computer to a second client computer linked via a communication network. A user of the first client computer executes a home client application and designates private data for roaming. The home client application generates a first key in response to a password, and encrypts the designated private data as a function of the first key. The server receives and stores the encrypted private data. A user of the second computer executes a roaming client application and requests transfer of the encrypted private data from the server. The roaming client application generates the first key in response to the password, and decrypts encrypted private data transferred from the server to obtain the private data. The invention further provides users the ability to retrieve encrypted private from the server even when the user cannot remember the password associated with the first key. Also, the server has no knowledge of the private data nor the keys.

    摘要: Detecting an attack on an authentication service. A first memory area is configured to store data relating to a plurality of requests communicated to an authentication service from a plurality of user agents. A second memory area is configured to store a predefined pattern of one or more requests. The predefined pattern characterizes an attack. A processor searches the stored data as a function of a query variable to identify at least one of the plurality of the requests communicated from at least one of the plurality of the user agents and compares the stored data associated with each of the identified requests with the predefined pattern to determine whether the identified request indicates the attack characterized by the predefined pattern. Other aspects of the invention are directed to computer-readable media for use with detecting the attack on the authentication service.

    摘要: A technique controls access to a file. The technique involves creating a file encryption key based on (i) a user input parameter (e.g., a user password) from a user of the client device and (ii) an automatically generated salt parameter (e.g., a random number). The technique further involves encrypting the file using the file encryption key to form an encrypted copy of the file, and providing the salt parameter to an external storage system to externally store the salt parameter. Access to data within the encrypted copy of the file requires the salt parameter provided to the external storage system.
