    • Delivering a Direct Proof private key to a device installed in a client computer system in the field may be accomplished in a secure manner without requiring significant non-volatile storage in the device. A unique pseudo-random value is generated and stored in the device at manufacturing time. The pseudo-random value is used to generate a symmetric key for encrypting a data structure holding a Direct Proof private key and a private key digest associated with the device. The resulting encrypted data structure is stored on a protected on-liner server accessible by the client computer system. When the device is initialized on the client computer system, the system checks if a localized encrypted data structure is present in the system. If not, the system obtains the associated encrypted data structure from the protected on-line server using a secure protocol. The device decrypts the encrypted data structure using a symmetric key regenerated from its stored pseudo-random value to obtain the Direct Proof private key. If the private key is valid, it may be used for subsequent authentication processing by the device in the client computer system.
    • 将直接证明私钥提供给安装在该领域中的客户端计算机系统中的设备可以以安全的方式来实现,而不需要设备中的显着的非易失性存储。 在制造时产生并存储在设备中的唯一伪随机值。 伪随机值用于生成用于加密持有Direct Proof私钥和与该设备相关联的私钥摘要的数据结构的对称密钥。 所得到的加密数据结构存储在由客户端计算机系统可访问的受保护的在线服务器上。 当在客户端计算机系统上初始化设备时,系统会检查系统中是否存在本地化的加密数据结构。 如果没有,系统将使用安全协议从受保护的在线服务器获取相关联的加密数据结构。 设备使用从其存储的伪随机值重新生成的对称密钥来解密加密数据结构,以获得直接证明私钥。 如果私钥有效,则其可以用于客户端计算机系统中的设备的后续认证处理。

    • Compounds are provided which are useful in the treatment of androgen receptor-associated conditions, such as age-related diseases, which compounds have the structure wherein R1 is hydrogen (H), alkyl or substituted alkyl, alkenyl or substituted alkenyl, arylalkyl or substituted arylalkyl, CO2R4a, CONR4aR4b, and CH2OR4a; R2 is hydrogen (H), OR3, SR3, halo, NHR3, NHCOR4c1, NHCO2R4c1, NHCONR4cR4d and NHSO2R4c; R3 in each functional group is hydrogen (H), alkyl or substituted alkyl, CHF2, CF3 and CON4e; R4, R4a, R4b, R4c, R4c1, R4d, R4e, R4f, R4g, or R4h in each functional group are the same or different and are hydrogen(H), alkyl or substituted alkyl, alkenyl or substituted alkenyl, alkynyl or substituted alkynyl, cycloalkyl or substituted cycloalkyl, arylalkyl or substituted arylalkyl, aryl or substituted aryl, or heteroaryl or substituted heteroaryl; R5 and R5′ are the same or different and are hydrogen(H), alkyl or substituted alkyl, alkenyl or substituted alkenyl, alkynyl or substituted alkynyl, cycloalkyl or substituted cycloalkyl, arylalkyl or substituted arylalkyl, aryl or substituted aryl, or heteroaryl or substituted heteroaryl, wherein at least one of R5 and R5′ is hydrogen, or R5 and R5′ taken together form a double bond with oxygen (O), sulfur (S), NR7 or CR7R7′; where R7 and R7′ are as defined herein; G is an aryl, heterocyclo or heteroaryl group, wherein said group is mono- or polycyclic, and which is optionally substituted; and n is an integer of 1 or 2, m is an integer of 1 or 2, Z is oxygen (—O—) or NR4h, a prodrug ester, all stereoisomers thereof and a pharmaceutically acceptable salt. A method for treating androgen receptor-associated conditions such as age-related diseases is also provided.
