摘要： Apparatus and method for generating a key stream is disclosed. In one embodiment, a cryptographic function is applied on input values selected from a first array of values to generate output values. Mask values are then selected from a second array of values and combined with the output values to generate a key stream block for the key stream. The first and second arrays are finite and may be implemented by a linear feedback shift register.

摘要： Disclosed is a method for protecting sensitive data in a storage device having wear leveling. In the method, a write command, with an associated sensitive write signal indicating that sensitive data is associated with the write command, is received. The sensitive data is further associated with at least one address pointing to a storage location within an initial physical storage block. The write command is executed by writing to at least one storage location within an available physical storage block, pointing the at least one address to the at least one storage location within the available physical storage block, and erasing the initial physical storage block to complete execution of the write command.

摘要： Disclosed is a method for evaluating resistance to cryptanalysis of a cipher structure having a diffusion element including a linear transformation placed between differently-sized confusion elements at an input and an output of the diffusion element. A generalized minimum number of non-zero symbols at the diffusion element's input and output is determined. The diffusion element's input is divided into subset inputs, each having a size corresponding to the size of each confusion element at the diffusion element input. For each subset input, a subset number of non-zero symbols at the subset input and the diffusion element output is determined. Each subset number is summed to generate a summed subset number. The summed subset number is subtracted from the generalized minimum number to generate a worst-case number. An upper bound of a maximum differential characteristic probability is calculated and used to evaluate the cipher structure.

摘要： A method for a server to initiate resynchronization with an access terminal, when synchronization has been lost, that cannot be exploited by attackers is provided. The server may provide the access terminal with a secret key that is only known to the access terminal and the server. The access terminal may store the secret key in a secure storage device to prevent the secret key from being hacked. If the server determines that synchronization has been lost, the server may send a resynchronization message to the access terminal with the secret key attached. The access terminal retrieves the stored secret key from the secure memory device and compares it to the secret key attached to the resynchronization message. If there is a match, the access terminal may initiate a secure communication link with the server to reestablish synchronization.
摘要翻译：提供了一种用于当同步已经丢失时服务器发起与接入终端的重新同步的方法，其不能被攻击者利用。服务器可以向接入终端提供只有接入终端和服务器已知的秘密密钥。接入终端可以将秘密密钥存储在安全存储设备中，以防止秘密密钥被黑客入侵。如果服务器确定同步已经丢失，则服务器可能会在附加密钥的情况下向接入终端发送重新同步消息。接入终端从安全存储设备检索存储的秘密密钥，并将其与附加到重新同步消息的秘密密钥进行比较。如果存在匹配，则接入终端可以发起与服务器的安全通信链路以重新建立同步。

摘要： Embodiments disclosed allow authentication between two entities having agreed on the use of a common modulus N. The authentication includes generating a pseudorandom string value; generating a public key value based on the modulus N and the pseudorandom string value; generating a private key value corresponding to the public key value; receiving a verifier's public key value; generating a shared secret value based on the modulus N, the private key value and the verifier's public key value; calculating an authentication signature value using the shared secret value; and transmitting the authentication signature value for authentication. When the authentication signature is received, the public key value and the shared value are generated to calculate an authentication signature value. Thereafter, the authentication signature values are compared and authenticated.
