摘要： A process is described for the recovery of rare earth elements from a sulphurous acid solution containing them. The rare earth elements can be successfully separated and recovered by solvent extraction from the sulphurous acid solution, being an organo-phosphorus compound as extraction agent. Di-2-ethylhexyl phosphoric acid or 2-ethylhexyl phosphonic acid mono-ethylhexyl ester is preferred as extraction agent.

摘要： An obfuscating apparatus creates a table for inputting the same number of arguments for multiplying and squaring operations, and sets the output values of the table so that the outputs may depend on the arguments. With regard to the squaring operations, there are added and tabulated adding operations using the arguments necessary only for the multiplications, so that the number of arguments is equal to that of the multiplication operations. The outputs depend on all the arguments, so that the presence or absence of the added arguments is unknown unlike the case in which dummy arguments that are not processed are added.
摘要翻译：混淆装置创建用于输入相同数量的用于乘法和平方运算的参数的表，并且设置表的输出值，使得输出可以取决于参数。关于平方运算，使用仅用于乘法的必要参数来添加和制表加法运算，使得参数的数量等于乘法运算的数量。输出取决于所有参数，因此添加参数的存在或不存在是未知的，这与添加未处理的虚拟参数的情况不同。

摘要： A tampering-prevention-process generation apparatus generates an output process instruction group to be executed by an execution processing apparatus in order to protect a first process instruction which causes the execution processing apparatus to assign a value to an assign-target variable. The tampering-prevention-process generation apparatus includes a branch-process-instruction-group generating unit configured to generate, as a part of the output process instruction group, a branch process instruction group which causes a processing route to branch to the first process instruction. The tampering-prevention-process generation apparatus also includes a dependent-process-instruction-group generating unit configured to generate, as a part of the output process instruction group, a dependent process instruction group which causes the execution processing apparatus to execute a process dependent on the value of the assign-target variable.

摘要： The present invention provides a migration apparatus that realizes safe migration of data between devise that use different encryption algorithms and different security authentication levels. The fourth electronic terminal device 2502 sends, to the migration authority 2501, a request for migration of a virtual machine to the fifth electronic terminal device 2503. If the fifth electronic terminal device 2503 is not an illegitimate device, the migration authority 2501 sends a migration request to the fifth electronic terminal device 2503. The fifth electronic terminal device 2503 sends, to the migration authority 2501, a digital signature and so on, together with the request. The migration authority 2501 makes a judgment. If the result is “OK”, the migration authority 2501 sends the result “OK” to the fifth electronic terminal device 2503. The fourth electronic terminal device 2502 encrypts a migration package and sends the encrypted migration package to the migration authority 2501, and sends the virtual machine to the fifth electronic terminal device 2503.

摘要： Provided are a utilization apparatus, a server apparatus, and a key utilization system which enable the utilization apparatus to control deletion of the old key without using a secure clock and allow encrypted communications irrespective of whether the accessed server has updated its key or not. In key utilization system 1, one or more server apparatuses 5-1 to 5-n each provide service to an apparatus having an apparatus key corresponding with a server key. Update apparatus 2 distributes an update server key to each server apparatus and a new apparatus key to key utilization apparatus 3. CRL distribution apparatus 4 distributes to key utilization apparatus 3 a CRL indicating one or more server apparatuses which have completed key-updating. Key utilization apparatus 3 holds both the old and new apparatus key, judges whether the server apparatuses monitored using the CRL have completed key-updating, and if affirmative, deletes the old apparatus key.

The obfuscating apparatus creates a table for inputting the same number of arguments, for multiplying and squaring operations, and sets the output values of the table so that the outputs may depend on those arguments. To the squaring operations, more specifically, there are added and tabulated the adding operations using the arguments necessary only for the multiplications, so that the number of arguments is equalized to that of the multiplications. In this case, moreover, the outputs depend on all the arguments, so that the presence/absence of the added argument is unknown unlike the case, in which dummy arguments not to be actually processed are added.
摘要翻译：提供了一种用于使程序分析更困难的混淆装置。混淆装置创建用于输入相同数量参数的表，用于乘法和平方运算，并设置表的输出值，使得输出可以依赖于这些参数。对于平方操作，更具体地，使用仅对乘法所必需的参数来添加和列表添加操作，使得参数的数量与乘法的数量相等。此外，在这种情况下，输出取决于所有参数，因此添加参数的存在/不存在是不同于其中添加了不被实际处理的虚拟参数的情况。
