| 发明名称 | Method and apparatus for providing broadcast service using encryption key in a communication system | ||
| 摘要 | A method and apparatus for providing a broadcast service in a communication system is provided. The method includes generating a key pair comprising a first key and a second key, generating at least one of forward encryption keys by applying a forward hash chain to the first key, generating at least one of reverse encryption keys by applying a reverse hash chain to the second key, generating at least one of encryption keys using the at least one of forward encryption keys and the at least one of reverse encryption keys, encrypting broadcast service data using the at least one of encryption keys, and broadcasting the encrypted broadcast service data. | ||

| 主权项 | 1. A method for providing a broadcast service in a communication system, the method comprising: generating a key pair comprising a first key and a second key; generating at least one forward encryption key by applying a forward hash chain to the first key; generating at least one reverse encryption key by applying a reverse hash chain to the second key; generating at least one encryption key using the at least one forward encryption key and the at least one reverse encryption key; encrypting broadcast service data using the at least one encryption key; and broadcasting the encrypted broadcast service data. | ||
