  • Methods and apparatus for synchronizing decryption state with remote encryption state
    Patent number: 9900291
    Abstract: Methods and apparatus for supporting secure packet communications, e.g., SRTP, which use implicit index numbers for synchronization and sequencing of received packets. The secure communications methods and apparatus having an adaptive index learning mode of operation and a non-adaptive index learning mode of operation. The adaptive index learning mode of operation being used to determine a correct estimated sequence number roll over counter number and the implicit index number for one of a plurality of secure packets received when an adaptive index learning process condition is satisfied.
    Type: Grant
