摘要： A method of controlling a buffer for reducing jitter in a packet network is provided, with a fast attack and a slow decay time to track delay changes in the network. The principal function of the method for controlling the jitter buffer is to minimize the delay within the buffer and use packet loss compensation in the event that the buffer enters an underflow condition.

摘要： A system and method for providing early detection of encrypted signals within a secure connection for voice over Internet protocol (VoIP). The system and method includes a non-complex, in-band, and early encryption detector within the voice path. A transmitter sends out a known pattern. Based upon the received pattern, the receiver decides whether its encryption capabilities match up with those of the transmitter. If the capabilities do not match, then the receiver waits for the signalling message for the correct mode of operation. No packets are utilized until the receiver and transmitter encryption capabilities are matched.

摘要： An apparatus and methods for facilitating an encryption process for use in systems employing cryptography based security, removes unnecessary data relating to encryption keys prior to storing the data after receipt of the encrypted information from a sender. Encrypted data, such as message data for multiple recipients, is analyzed to determine whether encryption related data for other recipients may be removed and/or whether a preferred encrypting process was used. In one embodiment, the apparatus and method also determines whether a non-preferred encryption process was used to encrypt encrypted data and re-encrypts the encrypted data with a different encryption process in response to detected non-preferred encryption key usage.

摘要： A method and apparatus for centralizing the processing of key and certificate life-cycle management is accomplished when security activation of a communication device has been detected. Security activation may occur at log-on of the secure communication device (e.g., a personal computer equipped with a security application, or applications), at activation of a security application, or at re-authentication of a security application. Once the security activation has been detected, the secured communication device accesses a depository of security information to retrieve relevant security information. The secured communication device then interprets the relevant security information to determine when local security parameters are to be changed. When local security parameters (e.g., encryption key pair, a corresponding encryption public key certificate, a signing key pair, and/or a corresponding verification public key certificate) are to be changed, the local security parameters are updated. Having done this, the secured communication device is then receptive to receiving access requests from a plurality of software applications. The access requests are each requesting that data created by a corresponding one of the plurality of software application be secured via the security application. In response to the request, the data is secured based on either the updated local security parameters or the existing local security parameters.
