Abstract:
1. A device comprising: an encoder configured to receive a speech sample and generate an encoded voice packet from said speech sample, said encoded voice packet having a packet size and a plurality of bytes; an encryption unit configured to receive a voice block and generate an encrypted voice block, said voice block having a block size, wherein said packet size is not divisible by said block size and yields a remainder; and a packet block manager configured to divide said encoded voice packet into a plurality of first voice blocks each having said block size, and provide said plurality of first voice blocks to said encryption unit, said packet block manager further configured to create a remainder voice block having said block size and including remainder bytes of said encoded voice packet, wherein the packet block manager is further configured to employ a pre-determined technique for selecting additional bytes from said plurality of first voice blocks, and further configured to include said additional bytes selected from said plurality of first voice blocks in said remainder voice block following said remainder bytes in said remainder voice block and provide said remainder voice block to said encryption unit.
