摘要： Provides a data processing system comprising a processor and encrypted information in a first persistent memory whose level of information leakage is higher than that of a second persistent memory. The second persistent memory stores a cryptographic key for decrypting the encrypted information, generating therefrom unencrypted information that is usable by the processor for executing an operation. The cryptographic key may be used for encrypting the unencrypted information, generating the encrypted information. Also provided is a method of processing such a data-processing system with an operating system, comprising writing unencrypted information into the first persistent memory, encrypting the unencrypted information under use of the first cryptographic key, creating therefrom encrypted information in the first persistent memory, and setting the data-processing system to a state in which writing into the first persistent memory is controlled by the operating system.

摘要： A method for providing a user device with a set of access codes comprises, in the user device, storing an encryption key and an identification code, and sending a message containing the identification code to a server via a communications network. In the server, an encryption key is stored corresponding to the key stored in the user device, allocating the set of access codes on receipt of the identification code from the user device. A look up function is performed based on the identification code received in the message to retrieve the key from storage. The set of access codes is encrypted using the retrieved key to produce an encrypted set. A message containing the encrypted set is sent to the user device via the network. In the user device, the encrypted set received from the server is decrypted using the key in storage, and storing the decrypted set of access codes for use by a user of the user device.

摘要： A technique for language verification of a Java® card CAP file is provided. The Java® card CAP file is converted from an original Java® code file while conserving its original Java® semantics. The Java® card CAP file is converted into a corresponding converted Java® code file that is semantically identical to the Java® card CAP file. In a language-verification step, the converted Java® code file is then verified if it has been found to comply with a predetermined language specification.

摘要： A space-efficient and flexible mechanism for implementing a virtual machine in a resource-constrained environment such as a smartcard is proposed. The virtual machine is designed for interpreting or carrying out instructions which are identified by an instruction code, also called opcode. Both, the addresses, respectively identifiers, of the functions implementing the instruction codes, respectively opcodes, which the virtual machine interprets, as well as parameters to those functions are kept within lookup tables.

摘要： A method for creating an object in a non-persistent memory is proposed. From an instruction code sequence, a first instruction code is read out which effects the execution of a first function which effects the choice of a non-persistent memory as the location for the next object to be created. This object creation is effected by the execution of a second function which is effected by reading out a second instruction code. Furthermore it is proposed to store a pointer to a transient object in the stack memory and to provide a mechanism for writing this pointer to and reading it from a persistent memory.

摘要： A method for transactional writing of data into a data space in a persistent memory. The data space has a data space header which signals that the data space is free. A data header is generated when there is a writing transaction in the data space. After successful completion of the transactional writing, the data header signals that the data space is occupied by the written data. The data is written directly to the persistent memory, and in the case the transactional writing is not successfully completed, the data space header is valid for the data space. If the transactional writing is successfully completed, the data header is valid for the written data in the data space. A persistent buffer serves for storing validity information for ensuring the validity of the data header or the data space header as appropriate.
摘要翻译：一种将数据事务写入持久存储器中的数据空间的方法。数据空间具有数据空间标题，表示数据空间是空闲的。当在数据空间中存在写入事务时，生成数据头。在成功完成事务写入之后，数据头表示数据空间被写入的数据占用。将数据直接写入持久存储器，在事务写入未成功完成的情况下，数据空间头对数据空间有效。如果事务写入成功完成，则数据头对数据空间中的写入数据有效。持久缓冲器用于存储用于确保数据头或数据空间头的合法性的有效性信息。
