    摘要： A mobile ad-hoc network (10) may include a plurality of nodes including a source node (11a) and at least one adjacent node (11b). The source node (11a) may include a wireless communications device for establishing a wireless communication link with the at least one adjacent node (11b), a plain text source (24), and a second generator (20) for performing a one-way algorithm using a secret key for generating a seed. Furthermore, the source node (11a) may also include a key encryptor (22) for receiving the seed and generating a key sequence based thereon, and a logic circuit for generating a cipher text for transmission over the wireless communications link and based upon the key sequence and the plain text.

    摘要： Various methods for implementing memory segment access control in a distributed memory environment are provided. One example method may comprise during a first write state for a memory segment receiving a cryptographic key stream in association with a request from a first device for use of shared storage capacity of a second device and causing the cryptographic key stream to be stored in the memory segment. Further, during the second write state for the memory segment, the example method may comprise receiving data content, transforming the date content using the cryptographic key stream to form encrypted data content, and causing the encrypted data content to be stored in the memory segment. Finally, during the first read state, the example method may comprise causing the encrypted data content to be provided to one or more requesting devices. Similar and related example methods, example apparatuses, and example computer program products are also provided.

    摘要： Various audio signal watermarking systems are known, which are also applied to digitally encoded audio signals. However, in current audio signal watermarking systems the watermark signal and its watermark payload do not survive very low bit rate audio coding, in particular parametric coding. According to the invention, a watermarked uncompressed audio signal bitstream is low-bit rate compressed, but the watermarking is removed and the watermark's payload only is transmitted together with the compressed audio signal bitstream. At decoder side, the received audio signal bitstream is de-compressed and watermarked again using the transmitted watermark payload. Advantageously, it does not matter that the compressed bitstream is not watermarked because the compressed bitstream can be encrypted prior to transmission.
