Abstract: Methods for increasing encryption synchronization availability include collecting encryption synchronization data from a first superframe received at a gateway. The encryption synchronization data is for decrypting media in a second superframe also received at the gateway. The encryption synchronization data from the first superframe is used to form a composite encryption synchronization codeword for decrypting media in a third superframe formed by the gateway, wherein the third superframe includes the composite encryption synchronization codeword and at least a portion of the media from the second superframe. The third superframe is sent to a receiving device so that media in the third superframe can be decrypted by the receiving device using the composite encryption synchronization codeword that is included in the same superframe as the media that is being decrypted.

Abstract: An apparatus, system and method provides an out-of-synchronization detection by using a network layer checksum. A process operating at an upper layer verifies that a checksum embedded in a network layer header is correct before encrypting and transmitting a data packet containing the header and a payload. The data packet is received through a wireless communication channel at a receiver and decrypted. A calculated checksum is calculated on the received payload at the receiver and compared to the received checksum embedded in the header. A key stream used at the receiver for decrypting the received encrypted data packets is determined to be out of synchronization with a key stream used at the transmitter to encrypt the data packets if the calculated checksum is not equal to the network layer checksum.

Abstract: A centralized password repository (CPR) provides network users with a password portal through which the user can manage password access to domains and applications on the network. A subset of the domains and applications on the network may be required, by design, to maintain a separate password infrastructure. For these systems, the CPR establishes a secure and authenticated communication channel and software on the system interfaces with the password infrastructure to synchronize the password in the system password infrastructure with the password in the CPR. For other systems not required to maintain a separate password infrastructure, the CPR performs password services by responding to requests from those systems seeking to validate user IDs and passwords. The CPR enables an administrator to modify network privileges and enables a user to alter passwords on the network through a single interface.

Abstract: A transmitting node produces synchronization data to be inserted into plain text and encrypts the thus generated data into multi-valued data so as to transmit the data. The synchronization data indicates the position of a running key used for encryption. A receiving node decrypts a signal including the synchronization data using the running key and detects the synchronization data from the signal to confirm synchronization of the running key between transmitting and receiving nodes. Then, the receiving node transmits a synchronization confirmation signal to the transmitting node. If the transmitting node does not receive the synchronization confirmation signal, it determines that synchronization of the running key is shifted, and re-synchronization is performed. To perform re-synchronization, a running key ahead of the position of the running key associated with synchronization data that has been stored is generated.

At least one of the sequences of activation signals inserts a preset amount of time after each activation signal transmission. If user input is not received within the preset amount of time, the next activation signal in the sequence is transmitted.

Abstract: Disclosed embodiments include a method for synchronizing a cryptosystem. In one embodiment, the method uses existing control data that is transmitted as part of a connection establishment process in a wireless communication system. In one embodiment, messages that are normally sent between a base station and a remote unit during the setup of both originating and terminating calls are parsed to detect a particular control message that indicates the start of telephony data transmission. Detection of this message indicates a point at which encryption/decryption can begin, and is used to synchronize the cryptosystem. Synchronizing a cryptosystem involves generating an RC4 state space in a keyed-autokey (“KEK”) encryption system. In one embodiment, Lower Medium Access Channel (“LMAC”) messages are used according to a wireless communication protocol. This is convenient because the LMAC messages are passed through the same Associated Control Channel (“ACC”) processing that encrypts and decrypts the telephony data.
