  • Patent number: 10129217
    Abstract: A first information handling system receives a security challenge and forwards it to a second information handling system. The second information handling system retrieves a private key from a public/private encryption key pair and satisfies the challenge with the private key. The second information handling system forwards the satisfied challenge without divulging the private key. The second information handling system is in a more secure environment than the first information handling system. The challenge may be satisfied by signing the challenge with the private key. Satisfying the challenge may be a step in creating a secure shell connection between the first information handling system and an organization maintaining the first information handling system and the second information handling system.

  • Patent number: 10114971
    Abstract: Corruption of program stacks is detected by using guard words placed in the program stacks. A called routine executing on a processor checks a guard word in a stack frame of a calling routine. The checking determines whether the guard word has an expected value. Based on determining the guard word has an unexpected value, an indication of corruption of the stack frame is provided. Some routines, however, may not support use of guard words. Thus, routines that are interlinked may have differing protection capabilities. In this situation, a determination may be made as to whether a caller routine supports guard word protection. Based on determining that the caller routine supports guard word protection, the called routine verifies the guard word.

  • Patent number: 10083308
    Abstract: Techniques are disclosed for efficient computation of consecutive values of one-way chains and other one-way graphs in cryptographic applications. The one-way chain or graph may be a chain of length s having positions i=1, 2, . . . s each having a corresponding value vi associated therewith, wherein the value vi is given by vi=h (vi+1), for a given hash function or other one-way function h. An initial distribution of helper values may be stored for the one-way chain of length s, e.g., at positions given by i=2j for 0?j?log2 s. A given one of the output values vi at a current position in the one-way chain may be computed utilizing a first helper value previously stored for another position in the one-way chain between the current position and an endpoint of the chain. After computation of the given output value, the positions of the helper values are adjusted so as to facilitate computation of subsequent output values.
