A context-showing and power-saving display information converting system and a corresponding apparatus are provided for lowering the power consumption of displaying images on a pixel self-emissive display device. The display information converting system includes a context-showing module and a power-saving conversion module. The context-showing module receives display information that describes the content of an image, wherein the display information includes one or more elements, and each element corresponds to a plurality of pixels displayed by a display device. In addition, the context-showing module determines a relevance of the one or more elements according to the viewing interest of the user. The power-saving conversion module converts the display information in unit of the one or more elements according to the relevance and provides the converted display information to the display device.

Power-saving and context-showing display information converting system and corresponding apparatus

Display information to be displayed by a display device having a power consumption model is converted according to a power-saving conversion model and the power consumption model, such that the power consumption of the display device for displaying the converted display information is lower than that for displaying the original display information.

Power saving display information converting system and method

A method and a system for secure authentication in a wireless network are provided. The method comprises the following steps. First, a network device and a client device of a wireless network authenticate each other with EAP-TLS. Wherein, the network device mentioned above is a gateway or an access point. Then, the network device and the client device generate a TLS master secret jointly. In addition, the method uses a distributed mechanism to prevent the consequences of the failure of a single AAA server, and to alleviate the consequences resulting from a violated network device. Furthermore, the method includes a multiple time digital signature mechanism achieved by performing multiple times of one-way hash operation to enable verification and revocation of certificate.

Method and system for secure authentication in a wireless network

The invention is directed to a method for applying a certificate suitable for a portable telephone belonging to a user, wherein the portable telephone comprises a telephone number. The method comprises steps of generating a user key pair in the portable telephone, wherein the key pair comprises a user public key information and then transmitting an applying packet from the portable telephone to a certificate authority through a switching center by using a short message service, wherein the applying packet comprises at least the user public key information. The user is verified according to the telephone number received by the certificate authority from the switching center. A certificate packet is generated by the certificate authority, wherein the certificate packet comprises at least a serial number and a certificate authority signature. The certificate packet is transmitted to the portable telephone according to the telephone number by using the short message service.

Method for applying certificate

A detecting method and architecture thereof for malicious codes is provided, which is applicable to a computer system having at least a host. Each host executes at least a process. The method is implemented with a system call interposition module and an analysis module for malicious codes. The system call module intercepts all system calls of process calls and all related arguments of the system calls. The analysis module for malicious codes analyzes the input data of pre-determined system calls, and executes the suspicious malicious codes. Once the same behaviors between the analysis module and the suspicious malicious codes are found, a system-intrusion warning is immediately triggered. The method is not required to maintain huge signature databases, and can detect unknown attack-skills in a manner of high correct rate and low incorrect ruling.

Detecting method and architecture thereof for malicious codes

A key management method to prevent illegal eavesdropping in a network system. Keys of the network system are divided into several family subkeys and several communication subkeys. A plurality of trusted-key centers are provided for respectively preserving a part of the family subkeys and one of the communication subkeys, and generating a one-way hash value involving the preserved communication subkey and an open information. Each of the trusted-key centers passes the hash value to an eavesdropper according to an authority certificate. Each of the trusted-key centers interchanges the preserved family subkeys according to the authority certificate to obtain a session key which is passed to the eavesdropper. The eavesdropper combines all the hash values from the trusted-key centers to obtain a corresponding communication key which is accompanied by the session key to eavesdrop an authorized communication.
